This whole PSI thing confuses me and in all the cars I have owned I have always been confused about this I am hoping that someone can help me understand what's a safe PSI for my tires. I read so much information..so many people have tried to explain to me, but I just feel stupid. Most of what I read is more so for upgraded wheels and tires so I not sure what applies to me and what doesn't... People have said no one ever follows what the sticker says is that because the ride is so poor?
I have 2011 Wrangler Sport all stock tires and wheels. The tires are 225/75r16 bsw on/off road tires. They are Goodyear Wrangler ST's. The Cheap base tires and wheels.... The door sticker says Cold Pressure is 35psi, but when I had them set to that it felt like I was driving on rocks I could feel pebbles in the road. I could feel everything and hear every single noise the jeep made. So I have been dropping them to over the last couple days per other Jeep owners which seems to be a standard practice of jeep owner. I am at 30psi now and it feels so much better. However, I do lots of long highway drives and was wondering over time is going to lesson the life of my tires? or make them overheat and result in failure? I would even go a little lower if I know that the tires I have could handle it.. Its only me in the Jeep for the most part and on occasion one other adult and small kids and on occasion 2 bikes on the back, so I cant see that requiring me to add air. I want the Jeep to ride smoother, but I don't want to make it unsafe. One more thing how can I tell what size tires I am running meaning 30's 40's etc.
I am going to want to take it off road, however, I want to do that when I get new wheels and tires which would not happen till next summer, so till then if its only going to be a street car I want it to be some what comfortable and safe for my family...
So far this jeep forum has answered so many questions I have had. Its a great tool have.. thank you!
