I have FD rims with Toyo Proxes on them. I also have an S5 TII. I was wondering what PSI I should have the tires on?

 

Depends, but I'd say 35psi+.

 

rule of thumb is always run 35, then adjust from there to your personal preference.

just never inflate it to the max psi on the tire. I think most cars run around 32 psi. at least most of the ones I did when working at a tire place did. I know the FC has a 32psi recommended. some places like Jiffy lube will actually inflate the tires to what's on the tire itself. which is a bad thing.
