    You need to swap all 4 wheels to see the full benefit. Doesn't matter if you're FWD, RWD or 4WD, all wheels act like flywheels and need to be accelerated by the car accelerating forward, not just the driven wheels.

    I'd argue this is a good mod for daily drivers too. I lost less weight per wheel than you and gained 2 MPG. That's an additional 30+ miles range per tank for me. Also, while I haven't officially tested anything else, it feels like the car is much happier and quicker around town.

  • @got.r3253

    To get the full benefit of light weight wheels, do all 4 wheels, then go to Willow Springs or Button Willow and get out on track. You didn't measure stopping distance and didn't measure skid pad handling. The ratio is 6 to 1, so for every pound of unsprung weight (especially rotating mass) its worth 6 pounds off the body of the car. Your handling will go through the roof and breaking will increase dramatically. In fact lightweight wheels and sticky tires will make you way more faster than adding 50-100 hp on an otherwise stock car. If you want to really make a fast car you have to improve the driving dynamics of the car not just the dyno sheet.

  • @bige8397
    @bige8397 ปีที่แล้ว +9

    The reduction of diameter and lower rotating mass combine for better acceleration and braking. Additionally, handling benefits as well as the suspension does not need to work as hard. So everything benefits and parts last longer working more efficiently (brakes perform better, last longer; suspension works better, lasts longer). I get the awesome look of large diameter wheels, but the smarter pick for the performance and operating cost is the smallest diameter you can safely get away with. One last thing, getting taller sidewall tires when dropping wheel diameter does dial back steering response, but adds more protection for your wheels and offers a better ride for street driven cars. If the streets where you mostly drive are not great, this combination is without a doubt a great choice.

    The difference is very noticeable on low power manual cars at low rpm. I guess in a 1.4l with 85hp you have like 20hp at 2000rpm, add the A/C on a hot summer day you may end up with 15hp. now, accelerating out of that low rpm (just everyday driving) there is a big very noticeable difference when you add heavier wheels.

    Weight is a good point but why no mention that 17s are actually smaller by 11mm( 225/45 17 is 634mm vs 645mm for 235/40 18) or so in diameter that definitely helping to accelerate faster than bigger tire.

      Thank god for this comment, I was starting to lose faith in humanity reading some dribble being posted here 😂. There is so much more to unsprung and rotational mass and it appears everyone reduces it down to simply reducing wheel weight with complete disregard for any other factors, ie overall diameter, never mind things like how that mass is distributed across the wheel tyre combo and impacts on lateral grip, positive or negative.

    Overall, lighter wheels and tires combo will always outperform heavier wheels and tires, but a fair comparison would have been to test like with like, i.e. the same sized wheels with different weights (using the same tires). This way you can then definitively conclude that the differences in your results, all things being equal, could be attributed to the differences in the wheel’s weight alone and not other factors likes the difference in the wheel sizes.

      Yes it does, you are correct that plays a part on this. It shortens the gear ratio. It is expected that lighter wheels will perform better, but this test wasn't very accurate. Different parts of the road and not enough runs after and before. It's fine though can't expect a small channel to go too crazy

      May not have been scientifically perfect, but you don't need to run a test whatsoever to know it's going to be better. Physics says it will be better. How much? That's the point really.

  • @bumponalog7164
    @bumponalog7164 ปีที่แล้ว

    Because drag is a major factor with acceleration at speed the effect of light wheels and tires will be much more noticeable at lower speeds as they will contribute a larger share of the forces to overcome. This is especially true for cars that can't spin tires in low gears.

  • @DjCyriss

    From what I remember it's every 1lbs off rotation it's like 0.10 sec off 1/4mile time or something close. Almost like taking 100lbs out of the car for every 1lbs lost in rotation.

  • @vdubsterw2516
    @vdubsterw2516 11 หลายเดือนก่อน +3

    This is all relevant to what type of racing you are doing. I race an mk4 at the drag strip every wed. And i found that the heavier wheel with a larger diameter tire will increase my 60 ft time vs my over all et time and my trap speed will be faster with a slower 1/4 mile time. The reason for this is because the diameter of the over all tire changes your gear ratio. Plus the heavier rotational mass prevents me from applying to much power in the first 60ft which allows me to grab traction better. If i reduce the tire diameter. I get a slower 60ft time but a faster 1/4 mile time with a slower trap speed. This is because the smaller diameter wheel is making the turbo spool faster but i lose the top end psi. There are way to many factors with just losing a couple pounds on your wheels. You have to take into account for your over all wheel diameter in relation to your gear ratio. You have to take in to account when the trubo spools in ration to you gear ratio. And when the turbo runs out of steam in relation to your gear ratio. After experimenting with many different tire sizes I found that just by changing from a 25.5 diameter tire to a 26 inch diameter tire on my mk4 made the car a 1/2 second faster in the over 1/4 mile time. And thats without going to a lighter wheel. So the larger diameter tire that matched my gear ratio at the end of the 1/4 mile put my rpm tap out right before redline. This allows the car to utilize all of its gears to the fullest potential in the 1/4 mile and still keep the turbo some what producing enough psi at the top end.

  • @Kirmo13
    @Kirmo13 6 วันที่ผ่านมา

    Changing the rims and the tire was a terrible idea.
    The theory says that lighter wheels are faster not strictly because of the weight, but because of the MOMENT OF INERTIA (or rotational inertia).
    It's basically the resistance to change in rotation of the tires and it depends on the weight, but most importantly it depends on how far from the center the weight is distributed.
    The old tires are 1) used and 2) different dimensions which is a big deal because of the weight distribution.
    And on top of that, changing only the fronts was not the best idea because in theory lighter wheels improve performance even if they are not powered.
    Lastly, there's the MASSIVE variable of new tires. It affects so much. Starting from the different wear, then they probably have different rolling resistance, different inflation, and different weight.
    Overall the video was nice, but the experiment could have been a little more rigorous.

  • @IgorBagayev
    @IgorBagayev 5 หลายเดือนก่อน

    When you switch from 18s to 17s, you're measuring the difference in diameter, not the weight.

      If you can get enough traction, go with the absolute minimal tire possible for the least weight. But honestly, adding a couple of PSI to the turbo would cancel out any of the benefit of all this swapping wheels and tires.
      Suspension action and steering would be affected nicely for track times if you're club racing. That's where it matters.

    I've got a 2004 VW Passat GL Wagon. American Spec. 5-Speed Manual with the AWM 1.8T. ATM Original Shadow Blue with metallic flake paint and Grey & Anthricite interior. Originally had the 15 inch steelies until I picked up a full set of the 16 inch GLS/GLX Alloys. Certainly helps. I even fully refurbished them. I do plan to purchase a set of 18s down the road and update/upgrade the suspension but first I'm going to upgrade the exhaust. The turbo, surprisingly, is still running well. However, I will upgrade that eventually as well. Having welders and buddies with other types of welders I thankfully don't need to be concerned with order. But is still interesting to see what differences can be proved or unproven.

    I love experimenting like this, for reference here is one you will like: 20 HP Loss On Dyno From Heavy Wheels WHAT? Stock 5.0 Mustang
    th-cam.com/video/5MUnG5hrEEI/w-d-xo.html
    This guy was using a Mustang and the wheel weight difference was 16 pounds but on a chassis dyno back to back testing he measured a 20 HP difference. So in your test the 7 pound heavier wheel probably cost about 6-8 hp.
    This is what most people don't seem to understand, when it comes to drivetrain loss, some of it is friction but most of the losses are due to inertia, and in any drivetrain there is nothing bigger and heavier, and creates more friction than all four wheels and tires. The one mistake you made is in thinking that because your car is FWD, that only the front wheel/tire has any effect, that is actually not true. Sure on a chassis dyno you see a big difference between 2WD and 4WD because you are only spinning two wheels. However, on the road when your car is accelerating it is having to spin all four wheels, and overcome the friction of four tires, it doesn't matter which wheels are being driven, most of the loss is the inertia of the spinning wheels and the friction from the tire to road surface. The actual wheels being driven is irrelevant, you would have seen a bigger difference if you had done all four wheels. There is a reason why dragsters run those skinny tires up front.
    On street cars it is always a compromise, even tire pressure can have a significant effect, most people lower tire pressure to get better grip off the line, but 60-100 where grip is not an issue higher tire pressure will reduce tire contact/friction and improve acceleration and fuel economy.
    Everyone was shocked when the FK8 Type R was pulling on the new slightly more powerful FL5 Type R. What they did not understand is that the FK8 runs a 245 width tire and the FL5 runs massive 265 width tires. Yes it is slightly smaller diameter wheel but it is the tire that weighs the most and is on the outer edge (more inertia), also more friction and air drag. When you consider these facts it is not surprising at all that the FL5 is actually slower with those tires/wheels. But they also allow it to grip around corners really well so... In that case it is worth giving up a little straight line speed.
    Great test, maybe try all four next time and try playing with tire pressure, you might be surprised.

    I think it could be slightly faster still with lighter 18s instead than 17s for the same total wheel+tyre diameter, due to with light wheels, tyre is heavier than alloy wheel, so more wheel and less tyre could be slighlty lighter and specially with less weight on the outer diameter where it counts most (because of same tyre width but lower profile, tyres can be lighter)

    Swapping all 4 wheels would make a bigger difference. And imagine comparing some cheap, huge, and heavy rims and tyres against some smaller light wheels and tyres. The difference could be easy 3kg per wheel. This means 12kg all together. They say 1kg at the wheel is like adding 7kg to the car. It would be like 7x12= 84kg. So it is like having a second person sitting in your car.

On a track or the twisties, it would make a difference too with braking speeds and exiting corners. People always want to add power but forget losing weight where you can is 'free' power (better power:weight ratio). I run 18x9 RPF1's on my Focus ST and its a drastic difference, over 8lbs over stock wheels (and thats mount/balanced comparison)

Camaros have lighter brake kits that can save 30ish pounds each front back for roughly 60-70lbs total loss, but they’re not recommended for street/daily because they’re so small. They’ll wear out fast and heat soak. Only good for drag racing etc. not worth it for the little gain compared to wheels which sacrifices nothing. Hope I explained well

    How would you use a different section of the road with a diff slope value? The stretch of road has to be the same. Also, the tire diameter has to be the same to have a comparison of weight only differences. A smaller diameter translates to an effective diff gear ratio increase.

    I think this test would have been more proper, if done with the same tire. The Cup 2’s have a lot more grip, which would essentially give a better time. So the time isn’t solely a matter of having lighter wheels.
    Also, your mph is also off now with 17” wheels (unless you recalibrated it through VCDS or OBD11). So the times you got are actually accurate. At 100mph on 17’s, you actually might only be hitting 95mph in real time, due to the smaller diameter wheel.

    *NEED TO BE PINNED* Fact: The lightest wheels you can buy are 18", are you confused because obviously 17" and 16"s rims are smaller and weight less? Yes but wait till you put your tires on (ding ding ding), 18"s you can get the lightest tires and smallest side wall, in which tires weight MORE then rims. Tire selections for 17" and 16", may times 15" are heavy and taller tires. Are you ready for another mind blowing kicker? You can have a smaller rolling radius in a 18" wheel package, then a ny 17" AND 16" wheel package in existence , aka, you can actually make your car sit lower with an 18", then a 17" or 16". The only variable that changes is if you have an compact car, running very small brakes, that allow for a then a 15" or 14"....yet you're then maybe a little insufficient in the braking department in the name of light wheels. Most people need to clear big brakes.
    It's a very funky chicken to have a 18" wheel (with tires) on the ground and roll up a 16" wheel, and the 16" are literally taller and heavier.

    Also, a tyre can lose well over 1 kg of rubber between new and ready for discard, and this loss of weight is also where it counts the most, on tbe outer diameter. My 235/35R19 Pirellis lost 1.3 kg of rubber each one between brand new and fully used up. That ks lile a swap for lighter wheels. So, light wheels and quite used up tyres = your beterr chances to get your personal record times (oh, and with increased tyre pressure, even more, for rolling accelerations)

      Because truck wheels are already small in relation to their tire OD reducing the weight of truck wheels will have a much smaller effect than on a low profile car setup. This is due to the location of the mass from center of rotation. Now if you get lower weight tires that would make a big difference.

    • @IJustAccidentallyThe
      @IJustAccidentallyThe ปีที่แล้ว +2

      The majority of weight comes from tyres from an off-road style setup. As mentioned above the moment of inertia comes mainly from the weight furthest out (the formula is radius squared).
      That is to say that you should focus on tyres and not rims.
      No one in the off road community seems to weigh tyres however. Very hard to find information on it.
