15" wheels 205-50-15 tires. psi=?
as stated in the title=
15" konig greenlights
205/50-15 toyo proxes 4 tires.
i've been running around 33 psi in my tires for some time, but they always seemed low to me. is there math behind psi in tires? does tire size matter?

Open your driver's side door and check the door jams for a sticker. It'll tell you exactly what pressure your tires should be at (tire size is not the issue). The only time this measurement is inaccurate, is when the car is either an explicit drag or track car.

thanks, but i'm well aware of the PSI marking inside the door jamb. my question was; does that change when you go with a smaller/larger sidewall? would you put 30psi in low pros? i do understand that PSI does not refer to the volume of air in the tire (like, more volume - more PSI). i know that's not the case. im just afraid of underinflating the tires and cracking a rim/wearing the tires weird. i live in new jersey, potholes are serious lol.

It's even in the FAQs
What air pressure should I use in my tires?
As a general rule, regardless of wheel or tire size or type, the best place to start is with the pressure recommended for your CAR, as shown in your owner's manual and on your car either on the door jamb or glove compartment door. Measure the pressure when the car has been sitting for several hours out of the sun, at the outside temperature at which the car will be used. Adjust from there in 2 psi increments as needed, based on tire wear and your preference for handling and/or ride comfort.
Do NOT set the pressure to the maximum pressure indicated on the sidewall of your tire.

No. The car's recommendation is still the best place to start. You can adjust from there as needed, in 2 psi increments, based on your personal preferences as well as any unusual tire wear patterns you experience. But the car's recommendation is usually pretty close to optimal. And it doesn't change significantly with tire size.
