This is a picture of my front tire, a PR4GT with just under 10k miles on it. I live in Nebraska, so this tire doesn't see many turns, at all. The stock pos Battleaxe showed the same wear, so I guess it's me, or the roads around here maybe? I saw a picture of almost the same wear in the "What Tires for 21" thread, so I'm thinking this may be common.
This picture is taken from the front of the tire, so left is right as you would sit on the bike. Notice the wear indicators, one is worn down to it, the other has a long way to go. This "wave" wear patter is bad enough that if I take my hands off the bars it will start to head shake, slowly at first then getting worse and worse (I don't let it get bad!). I run around 40psi cold, and ride in any weather above freezing. Thoughts?
