What should the tire pressure be on my 1995 Jeep Wrangler S 4 cylinder?
As mentioned look at the sticker on the door. Do not go by the side wall of the tire as the tire is meant to be used on a variety of vehicles. The correct tire pressure changes depending on the size/weight of the vehicle it is on. Same tire will require a higher PSI for a fullsize pickup than on a Jeep Cherokee. I good but time consuming way of determining the correct pressure is to mark a line across the tread of the tires with sidewalk chaulk. Drive your vehicle for a ways and see where the chaulk wore off. if it is in the middle only lower the PSI, if it is on the outside only raise the PSI if it wore off evenly across the tire you have the correct PSI.
