Hello all, I've searched but I just can't find a answer. Unless I'm just blind, no offense to the blind. But I plan on running Achilles atr sport 225/35-19 on 9" wide and 235/35-19 on 10" wide. What would you recomend as tire pressure? I know it's a light stretch compared to others, or atleast I think. Thanks in advance

Its kinda of an aggressive stretch. I like to keep my pressure at 40-45psi. im doing 225/35 on 9.5 and 245/35 on 10.5

dont know the LI of said tire but usually stretching involves running a tire that will be overloaded due to its LI being under OEM LI. (LI = Load index)

That being said you would normally run it higher than OEM since more PSI in tire = capacity to carry the weight is better.

Its not a recommendation just pointing out some tech facts. hope thats helpful.

Sorry I'm a lil old and dumb. But load index/speed symbol of 225's is 88W and 235's is 91W.
Don't know if what info I gave is right. Also this set up is going on a 98 ls400. Thanks again

I would not go lower than 42 psi all around. I'm running 44-46 psi all around....pretty much the same setup as yours, just different tire brands.

what EXE said. since your OE size yields a 97V load index and your new set will be 88W... youre going to have to over inflate then so it can support the weight of the car.
