Thread: Flat ridge in the center of front tire?

  1. #16


    Same issue on mine when I went on a 4k mile road trip straight down the highways. Got about 10k on PR3's and could have went more but it was a convenient time to get them changed and had another big trip planned. Ride that bike on some twisty roads and round those corners off.

    PR3's were introduced because there always has to be something newer and better. Just wait til you see the new PR4.

    Your tire looks to have normal wear for running straight roads at those pressures. There are Tread Wear Indicators in some of the grooves that indicate when the tire is worn out. I like to change mine when the groove is twice as deep as the height of the indicator bar.

    The PR2s on my R1100RS have the same wear pattern. I run about 36/40 psi F/R. A lot of my riding is on straight roads (I do live on the Texas Gulf Coast). My next tires will probably be PR3s and see how they wear.
