I ran mine at 32psi and got over 10k out of them and no uneven wear. Dropped them down to 17psi at the track.

holy crap lol. So many different results. I jsut want to make sure that they last a decent amount like 10k but still hook well on the street. Afraid the first pair will wear quick while I experiment lol. I may start out at about 23psi and see how they do. I won't be cornering fast. I may be using them at temps below freezing but it will only be a 2 mile drive to work on base at 30 mph. Then it will be much warmer in the day.

They are radial tires and not ment to be driven for long distances at low air pressure like 23lbs. You will wear them out fast that way and damage the side wall.
