    Low profile tires also allow installing larger brakes, which is important in sports cars as larger brakes heat up less and thus maintain better braking performance when being used a lot without sufficient time for cooling.

    There is also a big issue not adressed in the video: Unsprung mass
    Bigger rim diameter will add unsprung mass which has a negative effect on the power output of your car. You can compensate for that by using lighter wheels. Lighter because even same size rims from different manufacturers DO NOT weight the same. To get the best and most of your low profile setup you HAVE TO consider and compare wheel and rim combination. Even tyres do not weight the same. The less your combo weight will be the better your fuel economy and power output is going to be. If you ever experienced the feeling that your smaller rims allow you to go faster then your bigger ones (winter vs summer setup for example) then this is exactly the situation. Smaller rims and tyres usually weight less.
    And then there are multiple other factors to consider. Like tyre stretching. If you want little to no tyre deformation when cornering to give you the most control over your car behavior you can stretch your tyres a bit. The more you stretch them the more precise they will react to any changes deviating from a straight forward movement. You can overstretch your tyres as well leaving your car easy to drift. Cool if that is your aim but not so cool if that is not your main goal (as it may easily send you off the road into some ditch).
    Another thing to consider is your suspension. The stiffer yours is the more control it will give you. The softer it is the more forgiving it is. It highly depends on your target. What your aim is. You can have big wheels with soft suspension but also with stiff suspension. You can have the same with small wheels. Each combination will give you some benefits and some drawbacks as well.
    It is not hard to understand it completely and then look for legal (and reasonable) alternatives to your current car setup but it is definetly wise to resarch first and try later.

    • @DirtyTaxman
      @DirtyTaxman ปีที่แล้ว +19

      True, and not only acceleration is impacted by the higher unsprung mass but also the suspensions and dampers will have a lot more work, thus potentially lower grip on bumpy road as your suspension may not manage to rebound in time to push the heavy wheel back on tarmac.

    • @kramnull8962
      @kramnull8962 ปีที่แล้ว +7

      Only when installing a tire with a greater circumference and or wider than is going to be replacing the original tire. Same size tire but bigger wheel will weigh less in most cases. Because rubber steel belts per inch is heavier than most metals. You will then be simply replacing the heavy sidewall, for in most cases a few spokes and basically AIR. Tires are solid with metal cords bound inside the rubber compound, so essentially the sidewall you replace with wheel is just as solid/heavy as a wheel.
      Now if you go with a Wider wheel than factory, that's where you add the unsprung weight. Though really for street use, it is best to stick to a 8-9" tire wheel combo anyways; purely for driving in the rain and flooded road conditions. A wide tire will hydroplane way before a factory size 7-8" tire will. The wider the tire the more water has to be removed from the contact patch at once to remain stable and in contact with the road.
      Almost any rim you get will be much lighter than a factory option. You still have to weigh out if the lighter wheel is going to be safe enough for your weight of vehicle.

      Stiffer suspension doesnt mean better just as soft ones dont mean worse, thats just the idea people get when entering both sportscars and regular cars, there are variables like suspension travel and dampening that play a huge part in this, for instance when you buy coil overs for a stiff sportcar, you can actually make it more comfortable and forgiving whilst more engaging and better for track driving, it all depends on the setup you prefer.

    • @ArchOfficial
      @ArchOfficial ปีที่แล้ว +1

      You shouldn't care about unsprung mass of the wheel almost at all if you're serious about performance. Aftermarket "sports wheels" are made light by having them be flimsy compared to OEM and racing wheels. They might deflect in camber more than +1.0deg/yG. Most of the wheel compliance comes from the wheel itself, not from the upright or geometry, actually. You might get +2.0deg/yG easily, which means you'd need to run -2.0deg additional static camber, which will noticeably decrease straightline grip.
      Heavier racing wheels will add unsprung mass, but they will dramatically reduce wheel deflection. Heavier, wider tires will also dramatically increase grip. Due to this larger power racing cars usually have quite large unsprung mass. All that more unsprung mass will do is suck some power out, very minorly increase angular inertia if we're talking about wheels only here and they will decrease the unsprung damping ratio of the wheel which can be good or bad depending on the other damping ratios and the surface the tire will land on when it loads again. Brakes barely increase angular inertia at all so go as big on those as you can, the mass increase will not be a problem.
      Carbon wheels are starting to come out which allow a kind of best of both worlds, though.

      To slow the F1 cars down they have made them use larger diameter rims...
      Also - a couple of decades ago I bought a Jaguar that had factory fitted but massive wheels - 20" or something - it was second hand with about 40k miles on it but it was very noisy over bumps. I took it to a specialist and he showed me every suspension bush was shot and needed replacing. This was a combination of Jaguar at the time not having the best quality components but mostly the super low profile tires smashing the hell out of a suspension set-up designed for high side wall very compliant tires.
      This is what happens when you sport up a luxury saloon.
      Big rims are for 14 year olds and concept cars.

If you have a performance car it is not advisable to change the rims to smaller ones as it will compromise the performance the underchassis shocks, steering, was design for that. If you are not to spend much on upgrading your wheels just follow what good or suited for your car or follow what your heart desire otherwise stick with the stock or whatever the car have when you pick it up at the dealer.

      Not always look at traction and temperature ratings too, AA is better than A is better than B. The treadwear can be lower on a passenger car tire than on a UHP all season. Speed rating on tires also makes a difference a short lived S or T rated tire wont grip like a Z or W rated tire and I’ve had W rated UHP all season tires that lasted longer and gripped just as well as a W rated UHP summer tire.

    I had a '96 Accord EX F22b1/5spd some years back, and if anybody remembers the factory 15"x5.5" wheels, they were HEAVY. The 195/60-15 tires were barely adequate for the way I drove, especially with the car's 3009lb curb weight, so I replaced them with 17"x7" wheels, 215/45-17 tires, and the difference was night and day. The new setup was about 20% lighter, rode WAY better, and even though they were roughly ¼" taller, which dropped highway revs by about 200 (no advantage to dropped revs on the 145hp 2.2l), I got better mileage, most likely due to the weight savings. To take it up another notch, I installed adjustable ball joints, since the original ones were starting to show wear, and replaced all sway bar bushings with polyurethane. Cornering was much better, as was braking, but to take up some of the space around those tiny brakes, I switched the front calipers & discs to those from the station wagon, along with braided stainless hoses, and slightly more aggressive EBC brake pads. From there, my car had better manners, and braking than was ever intended, making my everyday sedan a LOT more fun to drive.

    I fully understand the theory explained in this video, but reality is that most UHP tire are wider than their touring counterparts. If you switch from standard or touring tires to Ultra High High Performance summer tires with a slightly wider and lower profile size you will definitely feel a big performance difference. It’s mostly a matter of the compound and tread pattern, but in the end you get a big boost in performance.

  • @andreysmirnov8892
    @andreysmirnov8892 6 หลายเดือนก่อน +4

    Great Video! I believe one thing can be added. Narrow tires INCREASE grip on loose surfaces, because they dig in much quicker. When a car is driving on a dirt (or snow) road, there's typically a layer of uncompacted soil (or snow) on top, a car basically floats on that layer, having next to no grip. A narrow tire with large treads will quickly throw away all that soil and grip to a much more dense layer beneath it. What's more, according to the law of conservation of momentum, soil launched rearwards by the car propells that car forward. I recommend checking out some footage from rally racing to see how that works. Rally cars spend most of their life is a slide to get more grip by digging in as fast as possible. And their dirt and snow(especially snow) tires are very narrow, too.

    Ones is theory and another is practice. You’ll have noticeably more grip on a slow car turning fast on wider wheels with low profiles then stock wheels. It does consume more fuel and you need to calculate fitment. But performance is definitely noticed when getting wider wheels turning around corners

    Good video. The only benefit with low profile tyres is the aesthetics. Most of us don't need the low profile tyres to do "high speed cornering" in our everyday cars. On the other hand, the comfort goes south with low profile tyres. Amazing how so many people walk into a tyre and wheel shop to downgrade their cars.

    • @klubstompers
      @klubstompers 2 ปีที่แล้ว +4

      If you tire is wider, you have more rubber to take the impact, than a narrow tire. Some low pro tires, can be just as comfortable as stock high pro tires, if the width is also increased, and the compounds used in the rubber are not super hard, and the psi is the same or lower. More stability with less deflection is a big safety upgrade as well. If you have to make a sharp turn to avoid an accident, take off from a stop quickly to avoid getting rear ended, or need to stop fast to avoid a front end collision, a wide low pro, is going give you that added performance, grip, and stability needed to avoid certain death. A wider contact point will also last longer, because there is less load per contact area. Wider all season tires usually also have better water deflection patterns to help alleviate hydroplaning. There are a ton of advantages of low pro performance tires over balloon tires, and aesthetics is just one benefit.

    I’m of the opinion that this information applies to 4WD’s as well as on-road vehicles.
    The key points being;
    1. Downward force on standard tires = less chance of wheel spin (except where the vehicle is operating close to and/or fully loaded at all times, one or two tire sizes above standard would be advantageous as there is a higher downward force)
    2. Wider tires are going to strike more obstacles on the track therefore stressing mechanical components and greater chances of a tire puncture
    3. When the tires sink / break through the track surface they need to push more mud / snow / sand out of the way there slowing or stopping forward progress
    4. Wider wheels / tires add to the vehicles kerb weight giving less carrying capacity
    5. Wider wheels / tires cost more and decrease fuel efficiency = more time at work and less time enjoying your life !

    • @thefunniestfarm4731
      @thefunniestfarm4731 ปีที่แล้ว +2

      I agree with all of it except point #4. Carrying capacity really isn't from from the tire up, but from the suspension up. Wheels and tires tend to be able to handle a lot more weight than the suspension/frame allows. The weight in the wheel isn't being carried, it is doing the carrying. On top of that: the bigger the footprint, the more it can carry, since it spreads the weight out over a bigger surface area.

      I thin k you left out a very important thing for offroaders to know. When you air down the narrow tire for rock crawling grip, you have to air down wide tires to the point of risking bead separation to get significant grip/deformation (2 inch). The narrow tires will do it at safe pressures and the contact patch really isn't that different even when aired up.

    Somewhat agree, just like you said if you don't change the dimensions of the wheel dramatically then it's ok. Like for example if going from a 185 or 195 to a 205 or 215 tyre in width it will increase braking performance and more stability and fuel consumptions mostly depends on the tyre compound and the brand of the tyre if you step up 10-20mm in width. If you buy a better quality tyre which is wider it might get better fuel consumption with increased grip, stability in cornering, better acceleration and better braking. Decreasing your sidewall a little bit will help with increasing performance without sacrificing a significant amount of comfort. Comfort depends on sidewall height, tyre quality, shock absorbers and suspension travel, and most importantly vehicle weight. You can't drive a Golf and expect a smooth ride, or a Chevrolet Spark. There is a reason why bigger and luxurious cars have a smoother ride. Also here's more complexity to this question, if you increase the quality of the tyre, for example you drive RoadX tyres which are low budget and switch to Michelins with a smaller sidewall and a bigger rim you might experience better bump handling and a smoother ride because the Michelin is a better quality tyre. Putting sportier tyres on your nonsporty vehicle will make it handle better but you will need other parts upgraded as well like brakes and shocks, because it's useless driving a monster truck of a car with sporty tyres. It's a somewhat complex question, you really need knowledge to find the right tyre for your vehicle. Stay safe out there.

    In a very simple situation where tire width is increased from say 195 to 205, there is a HUGE benefit in handling performance if all other factors are kept the same. I noticed this on my 500 Abarth, and I can safely say I made the better choice. Car feels more stable at high speeds (80MPH+) and cornering grip increased dramatically from the wider contact patch. I believe this video is touching extreme case scenarios, and not everyday enthusiast performance upgrades. If it was meant to steer people away from such upgrades, then this guy should try it on his own car and then remake this video.

    • @lucasrfma

      I don't understand much of the subject, but the one point the video seemed to get wrong to me was the traction part. I don't think the wider tires have less traction as the video say, and I think it shouldn't be more traction as you say either. Since the wider the tire there will be less weight per unit of area, thus less traction per unit of area, but proportionally more area to compensate, leading to same overall traction, with less wear on wider tires. So the determinant factor should be the type of rubber, as well as tread design.

      @@lucasrfma Pretty sure he misspoke and didn't bother to correct it. In my experience, wider tires on the same rim require a slight change in pressure to achieve optimum contact patch which makes the tire conform better to the road being less stiff. I check mine with garden lime to see what the contact patch looks like. He was right as far as he went in cornering grip but he didn't go far enough. You can actually gain cornering grip by the sidewall flexing because it only flexes so far because if it didn't the tire would flex until it came off the rim. The sidewall flex actually allows the tire to maintain the contact patch, like on my 71 mustang that stock came with F70/14 and I ran them at 22psi for maximum grip. Yes in curves it gave a "greasy" feel until it had flexed as much as it would but then it was planted through some remarkably tight S curves at over 100mph.

    I remember reading somewhere that the contact patch area is the same no matter the width of the tyre because the weight of the vehicle is he same. How it works is in narrower tyres, the width is narrower, but the length of the contact patch is longer. In wider tyres, the width is wider, but the contact patch length is shorter.

    Moment of inertia (energy required to acellerate/decelerate it about a central point) of the wheel & tire combination increases with bigger weight, width, and the square of the radius.
    Also, outside diameter of wheel/tire may change the effective gear ratio.
    For economy, lightweight wheels(as long as they'll handle the the load) as close to the brakes as possible and a narrow tire will also have better fuel economy, bonus if it's a 'disc' style for a little bit of aero too...

    Everyone likes buying low profile tires like sports cars. When you (?) put it on you are not so sports car (?) to look cool, you can feel every road imperfections, get a load of flat tires, and a fuel drinking monster. So after spending so much money you get the question:
    Why do these tires even exist? And do they offer any performance advantage? Why do sports cars use it at all? In this video, we'll answer all these questions.
    So, let's untangle how low vs high profile tires and wide vs narrow tires vary in performance.
    To understand the effects of low and high profile tires, let's compare two wheels of the same outer diameter but one with bigger rims and low profile tires, and another with smaller wheels and high profile tires. Rubber is like zewel (?) having more or less of it has its own advantages and disadvantages. High profile tires has more flexibility. So on boat holds (?), speed bumps, and bad roads, the tire itself absorbs more shock. That's why most cars, trucks, and offroaders use high profile tires. The high profile tires also has its own disadvantages due to more flexibility, like wrinkling at high acceleration, which is just not good for tire life, and tire deflection and cornering,

    I disagree on handling part of wide tires because when you're doing performance driving on twisty roads wider tyres keep the car more in control while taking corners from but there is thing about going too wide as it does increase unnecsessary fuel consumption and this annoying deadzone on the steering wheel so finding the right width for your specific car and your driving skills is important

      What he's saying is the wider the tire the less pressure (from weight, per square inch) on the contact patch. Imagine a pinpoint contact patch on a rear wheel of a 4,000lb car. That point, in this made up scenario, would have all 1000lbs from, let's say, the left rear of the vehicle. Now the wider you go with bigger contact patch, that 1000lb is spread out more across the contact patch, and less pressure pressing the tire against the ground per square inch of contact patch, thus the need for downforce. I'm glad he talked about that because I was not thinking about that at all, I just figured the wider the better, but clearly this is not true unless you have enough pressure (from weight or downforce) per square inch of your contact patch to keep the tire from slipping

    I have 300s on my car, on dry tarmac I can feel the added grip, especially at high speeds. I have taken some turns that would have surely killed me with thinner ones. Huge disadvantage is in the rain, I just can feel the rear of the car going from left to right at every puddle. Also the fuel consumption went up by 2 or 3 liters/100kms, no joke. Looks dope tho.

    Ok, my BMW X5 has 19" diameter rims, the front is 9" wide and the rear are 10" wide. The car is an all-wheel-drive diesel 3 ltr 6 cyl and whilst it does have a transfer case it does not have high or low ratios. The drive split is 49/51 front/rear and the weight is just over 2 tonnes without passengers or load. It handles like a sports car, except for the ride height and runs on 255/50R19 front 285/35R19 rear. By driving sensibly, I have already defied the book's figures in relation to fuel consumption. I definitely agree with you on your analysis of oversizing your wheels for looks will cost you at the fuel pump and the comfort, I have been through that phase myself and experienced exactly as you said. I soon changed to a point I believed was the sweet spot between looks and economy back then. But now, I am truly baffled by this offset wheel assembly that is a factory fitting and on an all-wheel-drive vehicle. Also the ability to get better than stated fuel economy and not by any onboard computer, but by measured mileage and refill data. If you have any views, I would be glad to hear them.
