Tire Pressure: Do This to Save Fuel

- With fuel prices hitting record highs, thanks in part to the war in Ukraine, you need to do what you can to cut fuel costs. The secret to better fuel economy is proper tire pressure. Too high or too low and you'll be burning more fuel, wearing out your tire prematurely, and potentially causing an accident.

Going by the door jam is wrong unless you have the factory tires on the car since every tire has a different load rating at different max psi compared to the factory tire that came with the car. The only way to be sure you have the correct pressure is to caulk line test it. With modern radial tires it wont really hurt to run them a bit on the higher side. Higher psi around 40 will give the best wear and mpg for most small and midsize cars but again it depends on load ratings of the actual tire.
The gas prices are high because of the sanctions. Other countries are actually paying less for the gas.
Thanks for the review and information. I would respectfully say that the subject of over inflating the tires benefit is: it depends on the driver and the average speed. For highway driving due to aerodynamic resistance there is no benefits and increases of unstable handling so it does not make sense. For people like me who have been over inflating for years, who drives within speed limited non aggressively and mostly below 80Km/hour locally, I do see increases on the mileage and no issues of handling issues in my CrossClimate2 All Weather tires.
George, I'm glad it's working out for you. I haven't tried it myself, so I can't say from personal experience. I'm counting on the wisdom and insight from the folks at Popular Mechanics.
You’re factually wrong. Overinflated in safe and small amounts actually helps. It reduces rolling resistance which in turn positively affects fuel economy. You’re wrong, just stop. The vid is accurate.
@@jacktalkstires there are way too many variables in that test done by Popular Mechanics. Higher pressure will reduce rolling resistance if you can tolerate all the compromises. Underinflation hurts more than overinflation helps, but it does help.
What should be recommended tire pressure
@@awaisiqbal8934 To find that answer for your vehicle you need to understand that the "correct tire pressure" stated at your car frame is based at 20°C/68°F temperature. Once the tires are inflated correctly based on the correct temperature you can start trying with a bit extra pressure at a time in all different driving conditions as each vehicle will reacts, behaves and response differently. Stop at any moment when you do not feel safe and rest it back to the factory level or last know safe pressure you have tested with. Cold Inflating Temperature: en.m.wikipedia.org/wiki/Cold_inflation_pressure
I see the one piece of most important information gets left out is: what does "COLD TIRE PRESSURE" means. A cold tire can be under the shade of a tree in the Arizona dessert or on top of the snowy Rocky Mountain with huge temperature differences so what is the standard of the "COLD TIRE PRESSURE" on the sticker? "COLD TIRE PRESSURE" on the sticker means that the pressure listed on the sticker is based on the ambient temperature of 68F/20C; therefore, the air would need to be either added or removed if the ambient temperature is over or under 68F/20C when checking for the correct tire pressure. For more information on how get the correct tire pressure please use the link provided: en.wikipedia.org/wiki/Cold_inflation_pressure
1:38 A gallon is 3.785 litres, if one litre comes at $2 and a gallon $5, i am already saving huge by going gallon 🤣
Original tire size 205/60r16 with 220 front & 240 rear, i change the tire size to 215/60r17, the air pressure is the same o do i need to fill a bit?
My car has 35 in front and 33 in the back as recommended, is it ok if I accidentally overinflated the back to 35 making them all the same pressure?
Hey Cool Guy69! Great question. My SUV is the same - 35 in the front, to help with the extra weight of the engine, and 33 in the back. I don't see a problem with the extra 2 psi, especially if you use the cargo area from time to time to haul stuff.
My compressor tops my tyres up 0.5psi extra.
Yeah all the war. Has nothing to do with wreckless spending.
I know Jack talks tires, and he is right about saving money on fuel with correct tire pressure. However, I would have made mention to the fact that driving over 50 mph/80kmh begins to reduce gas mileage quite a bit, unless you're driving a sports car whereas some actually stay the same or even get better the faster you go. The savings from going slower far outweigh tire pressure and it makes me wonder in a world trying to save fuel why speed limits are increasing and not the other way around.
Hey there ottawa drone. You're absolutely right about the speed limit... however, few people want to drive that slow. That said, you make an excellent point.
@@jacktalkstires Years ago I had a 1985 Toyota Supra and the diff was bad (very common for those cars) and I couldn't drive more than 90kms/hr without major vibration until I got it fixed. I couldn't believe how much gas I saved and it was a sports car. I see these huge pick up cruising along at 130kms/hr and I can just imagine how much more it costs them. One would think with all the climate change crap going on that "they" they would convince people to drive slower....nope. Great channel and I have a saying, "tires and batteries". I'm forever fixing and replacing, tires and batteries.
@@EverybodyLovesMoe Thanks for sharing your experience, and for the kind words. Much appreciated
I have one sit on the door jamb and another on the gas cap
WADR it is not practical to check tire pressure every week or even every 10 days. Possibly if we do that there would be more line to check tire pressure at petrol/gas/diesel station than to actually fill fuel in vehicle. I prefer to fill approx 2 points above recommended on vehicle's door label in summers. Then check every 30 to 45 days. If doing a road trip, then fill just 1 above recommended. While in winters as temps can vary a lot, I usually fill 3-4 above recommended, check every month. Driving in fuel speed limit of 55-60 mph whenever feasible, avoid going beyond 75 mph will give you overall pleasure and good fuel efficiency as well. This is applicable to most sedan cars, SUVs, pickup trucks and even motorcycles. Dry more efficiently and our next generation may thank us for it.
Most people top their air up whilst they're still warm
I had a tire under 10psi under recommended psi, (but the tire was solid and wasn’t sagging at all) should I be worried about tire wear ?
Definitely
