- How does tire pressure affect a car's stopping power?
Let's find out!

goes to show: less pressure = more area for the tire to grip = less stopping distances
More contact area = more weight distribution, i.e, less pressure
And more resistance to rolling
@@maakikursi2860 yup, you can see this by the amount of throttle the car uses to maintain the speed. It it noticeably higher on the car with low tire pressure.
No that's completely wrong. Given they are the same mass and that friction force is equal to coefficient of friction multiple normal force (hence no dependence on area).the reason for that is increased Rolling resistance to prove my point if he was to measure fuel consumption you would notice it imcrease
But... How will that affect the tire's durability then? I tried to reduce tire pressure to minimum in Street Legal Racing Redline, and let's say that it worsened tires durability even on expensive medium compound tires (with higher width of course) somehow
Fun fact: when off-roaders drive on sand they slightly deflate the tires to get more traction.
Yup, it helps a lot. I’ll drop my truck tires from 38 to 22~ psi when going on sand. I can go lower but just haven’t needed too yet.
This is common knowledge
@@Hunter-nb5bjshit I run 20 for casual driving no bl
I think the results are realistic. While yes, in real life this isn't applicable due to safety regulations and handling changes, this experiment was very realistic and true. The simplistic version, less PSI equals more grip in a straight line, therefore more traction, so more friction for the slowing of the tires and wheels by the brakes.
Also with a lower tire pressure, the wheel has a overall slight decrease in diametere, slightly increasing leverage for the brakes

You can see the effect on the throttle usage, especially at the higher speeds. Less PSI = more resistance = more throttle = higher fuel consumption
Yet the downside of underpressuring the tires is potential to have the inside of the tire’s material eaten away and have a premature failure
If your tires have enough grip, it will have the same effect. So having grip tires is good not only on different sports cars - it can just save your life at some point when you need to brake quickly.
Slightly better braking, much worse cornering and tyre wear. Not a good trade off 😃
Great now do cornering grip comparison high vs low tyre pressure on low, med and high speed corner. see who pulls highest cornering speed and Lateral G before understeering or oversteering.
Drag Cars, MotoGP Bikes and Race Cars (as far as i know) use low Pressure as well. But those are special Tires too. But yeah, lower Pressure, more Rubber to the Ground, a little more Traction. But i wouldn´t decrease my Tirepressure because of this, it comes with a whole lot of other Problems. Bad, indirect driving behaviour, Tire overheating on long Trips and higher Speed (German here, Autobahn^^) and bad fuel economy.
30 psi is still a normal tire pressure. I've seen some people coming in the shop with 45 and even 60 psi. This is where brake performance is dangerously bad.
Only slightly better but the downwards are catastrophic
Oh I always thought properly inflated tires improved stopping distance
More rolling resistance with underinflated tires
Very nice.
well 30 PSI is also really really high, i doubt the difference would be noticable if the high tire pressure was say, 25 instead of 30. Most racecars including F1 cars usually use 16-17 psi, or at least between 15-20

I can't read imperial units lol
I guess I'm never running high tire pressure in any car I ever own then
Well 30 PSI is ridiculously high for a car this size so
@@TheDeathintherain in sweden its like a standard of 2-2,5bar which is 36psi
