the final tally on the front was 14481! There were some miles left on it, but I needed to change because a ride is coming up. It was noticeably lighter than the replacement. The rear had about 10,500 when it was replaced
And, while at Baton Rouge BMW last weekend I saw a flyer for the PR3s. There were graphics showing the pressure points during turns vis a vis the sipes and treads. From those pictures my wear is not unusual at all, it is the norm.
Also, while the rim was bare, with all previous weights on, I put it on the marc parnes balancer. Removing some weight and adding some, I balanced the naked wheel. Then I installed the tire...
backwards
so I got to do it all over again.
When I put it on the balancer it was pretty close to ideal, close enough for sure.
