even the spec on the stock 17s are 32psi, how you can run anything lower than that.

i think you can run 32psi, that's the factory spec on 16s and 17s if i am correct. but for 18s, i might put it at around 35psi to give it more pressure.

I run a 245/40/18 Toyo T1-S on my truck at 40 psi. Don't even think about going less than 35 psi but if you're still not sure call around to a few tire shops and get a consensus.
