225-35-19 kumho ecsta supra 712 , ok ive had these wheels for about 2 years know and i dont know exactly what psi i should have them set at the tire says 50psi max i usually have them around 34-40 psi what do you guys think?

 

around 30-32 psi

 

That range is fine, depending on conditions and your intents. I typically run 36-38 front and 32-34 rear, for improved performance as an aggressive daily driver. If I were looking for max comfort and best tire wear, then I'd slow down and run 32-34 front, 30-32 rear, with a couple more psi if I were doing a long highway trip. This is regardless of tire size on the tC, same PSI for 17, 18 & 19".

FWIW.

 

i run about 40...ride is stiffer, but i dont feel the potholes hitting my rims anymore...tire guy told me to do it to avoid denting my rims...dunno if its true....
