I just ordered the above size tire (Pilot Sport 3+) to replace my F1’s (P245/45-20) on my 13 R/T.
What pressures are you running with this size tire on the stock wheel?

Thanks

You'll be good at the same stock 32 psi.

Thanks 72.
I will still do a chalk test but I will start with the 32psi. Knowing this will start me in the ballpark
?

Looks like the new tires have a 101 load rating so 1819 lbs vs the stock 99 of 1709 lbs, so you could probably run 30 psi or even less for a smoother ride if you don't push it or ride around at max gross weight.

The Load and Inflation Tables are your friends....

Thanks guys!

My current 245’s show more wear in the middle after running 33-34psi. So 30’ish sounds about right for the larger tire?

Thanks again

The tire place put 38 & 39psi in them?

The tire place put 38 & 39psi in them?

.....and those same brainiacs also balanced them and secured the lug nuts.

I checked them and they are tight.?
I am going to test 32 front and 31 rear tomorrow. Then I may drop them to 30 for another test the next day.

Thanks!

 

[Yo7_A66]

I test drove the 32psi front and the 31psi rear with the P255’s. That was much smoother than the 38/39psi from the tire dealer.
I may drop it down again to 30/29 tonight for tomorrow’s drive to work.
Thanks again!

Today I tested 30psi front and 29psi rear on the P255's. Still felt good around corners, and on the highway at 75mph, and the bumps feel comfortable. So I did a chalk test and they both look good. It almost looks like the rears could go down a psi or two. But this is with no one in the car.
Thanks again!
