What PSI do you run on the street? (On 35s)
Hey guys, I am relatively new to wheeling, got my first Jeep JK about 2 years ago and have been learning ever since. One thing I have always bounced around with is what PSI i run on the street (its my daily). Obviously, i love the soft, smooth ride being around 25-30psi, but I know it is killing my gas mileage and tires. My main question is, what PSI do you run on the streets? Also, can I do harm to any components running too low pressure on the streets?

The height doesn't matter so much as the width of the tire and the width of your wheel.
Factory wheel (7.5") and 12.5" at a 'normal' street pressure will eat through the center of the tire. I'm running that combination at 32- the ride is what it is but I can rest assured that when I get on the brakes or have an evasive maneuver to make, the jeep will respond exactly as I expect.

Just picked up a 2020 Rubicon with 4K miles and a bunch of mods. I noticed the steering was twitchy. Looked at the tire gauge and 2 tires were at 75 and 2 at 60. I know crazy.
Wheels are fuel and tires are 35x12 BF Goodrich mud terrain. I’m thinking 35psi max? The tire shows 75psi on sidewall.
Let me know what you think.
