After reading the posts about some folks getting up to 20,000 miles on sets of tires, I am trying to figure out how to get there. I am running Dunlap E4's, and have just over 10,000 on them, and will need a set (at least back) soon. My tires wear right in the middle, a pretty narrow strip (except of course until I get in the twisties and get my hellacious chicken strips...not far from the center). I run 42psi rear and 41psi front. I am wondering if I lowered the pressures a bit, if that would allow more tire area to contact the ground, and possibly get a little more wear out of the tires?
I started a thread a while ago about how every air gauge gives me a different reading, so who knows how much we are really putting in our tires. Perhaps mine are over inflated? Would lowering the pressures actually help more tread make contact with the pavement, and extend the life of the tire, at least in theory, or would it eat it up faster?
