What PSI is everyone running on the street with what tires?
Trying to get a grip on what street PSI i need to be running. Was at 36 and just went down to 30 on toyo R/T 285/75r18's.

Tire width and rim width are two factors to be considered with this topic. The other elephant in the room is "what purpose do the tires serve"?. If they're for maximum mpg's and a little stiffer ride then pump them up. If you're looking for a "flat" wear pattern, drop the psi.
Stock wheels with 275 cooper's and 255 goodyear's- both at 34-36 psi for a flat pattern and maximum mpg. 40 psi would probably give me another 1/2 mpg, but is it worth the reduced tire life and ride quality, nope.

Im at 28psi with my falken wildpeak 285/70/17's
Iv got a heavy jku, bumpers, sliders and winch. Chalk testing yielded me my psi for best wear. I had run as high as 38 before and got a little better mpg (about 1.5+) but the ride was too stiff for me and I want to make my tires last. Tires be expensive!
