tire pressure, mpg, ride quality
I did a search and couldn't find a thread directly relating to what I'm wondering.
I bought my YJ about a month ago, and just yesterday checked the tire pressure. I figured he probably had it around 32 just based on what most people fill their tires too.
I was wrong. They were at 12 (driver side), and 10/11 (passenger side)
I have 31" Super Swampers. I've been getting about 13mpg (3.07 stock gears). I aired them up to 20 PSI this morning and my ride felt nicer, and my tires were quieter on the ground. What is the optimal tire pressure for fuel economy, comfort, and tread wear?
My tires have a 2450 lb max load rating @ 45 PSI cold. I figure I'm theoretically okay at 15 PSI, but put it at 20 to test with. I'm going to get some chalk this weekend and check to see what kind of tread pattern is actually hitting the ground. Suggestions?
