What pressure should I run in my 315/30/18 toyo r888's for the most traction on the street.

 

28-30 so you don't cause irregular wear.

 

Thanks. This is my first set of tires I got that I can't rotate so I am worried about them wearing unevenly.

 

I've only had mine on for a couple weeks and a few drives, but I did notice that pressure would rise from my baseline of 26psi cold up to around 30-31psi once I got some heat in them (quick hazing in 1st gear and a couple of blasts down the highway). I hear 30ish hot is ideal. They'll hook about 3/4 throttle in mine in 1st gear and deadhook 2nd from a 50 punch once warmed - I'm making 520whp thru an unlocked 4L80E with 3.23 rear-gearing (when the car was a 6 speed it made 634wtq around 4200rpm, so it hits the tires hard and quick when it sees full boost). I'm pretty happy with these tires for street duty so far considering when I did test them it was around 55* outside, ready to see what they do in the summer heat!

 

Do you have them on all 4 corners.

 

nope, I got some cheapo tires in the front.
