When I put my new 19" wheels, I am going up a size on the tires instead of the OEM 19" tire size. Does the tire pressure need to stay the same PSI? I am going to be running 245/35/19 and 275/35/19.

Any idea on what it should be at then and what the factory PSI is for 19"?

 

i would say between 35-38 and you should be fine
