Higher tire pressure=less turning ability?? - Toyota Yaris Forums

I deliver pizzas and have take turns at the highest speed possible...so should I still crank up the pressure? I already squeal the tires about once a day while turning.

Also i live in FL so the temp will be over 100 in not too long.

You will have turning ability, but at higher psi you will have less turning 'traction'. For your case I would use around 30 -32 psi. IMHO.

Cheers!

If you crank the psi in the tires say the tire is cold and you have it at 50psi. If it is 90* outside you might have a "hot" tire pressure of upwards of around 65psi. This is why I NEVER run more than what the sidewall on the tire says. Its stupid to run more for a couple extra pennys when you don't know what could happen to you or others.

i would agree you should just run the pressure at 32psi. The other thing I would mention is you should not be able to reach speeds where traction would be limited on public roads, unless you start doing crazy u-turns. A speeding ticket kills income on any driving job.
