Hey guys I recently put on my 18x7.5 Racing Hart Evolution C5s with Toyo Proxes FZ4 235/40/18 and I wasn't sure what PSI I should be running. The place where I got them balanced and aligned put them at 36 all around. After the past few days where New England likes to be 60 during the day and then 20 at night, I have been losing PSI over night down to 29 the other morning when I woke up and checked which is quite a bit so I've had to fill up the air a few times. I've been putting them at 37-38 myself (tire says max psi of 44)...I just wanted to see what some others out there are doing. Thanks.

but yea, i'm also interested. first time with 18s. what problems can happen if you run max psi? horrible tire wear?

over inflated tires will wear in the center, its just the opposite for under inflated tires. mine came at 37 psi.
