Hello,

Is there a formula to determine what is the ideal tire pressure for running a 20" rim with 305/50 R20 tires?

I got my H3 recently and today I checked the tire pressure for the first time and they are all at 45psi. Is that kind of high?
My tire pressure warning light came on today too for the first time in two weeks. I wonder if it is attributed to running at 45psi which may be above factory preset PSI.

Thanks in advance for your knowledge/tips

Somewhere on the sidewall of the tire, it should tell you what to run that specific tire at? If the light for the tire pressure comes on, it because it has a different preset than your current tire. Im sure there is a way to eliminate that light but i cant say for sure.
