I upgraded to 18" 225/40F and 265/35R wheel/tire combo. What should my tire pressures be? The same as in the owners manual for the 16" stockers?

thanks

 

I think a lot has to do with personal preference, how the car drives and of course - the make/model of tires that you are using. I'd start with something like 33lbs and go up or down from there, depending on how the tires react and your driving habits/style.
