    hardware or tuneup

    how much are you talking? does it shake on these runs? i've seen heavy shake move the tire 6-8 inches in one run.

    if it's going more than 6" a run, it's probably a hardware problem. either the rims are slightly undersized or the liner isn't clamping the bead of the tire good.

    the problem with the goodyear liners is you have to trim them back in a certain area to get air in them, if the tire turns past that, you can't get air in or out.

    also tire rotation is a problem because it throws the balance off.

    You can also trim the inside edge of the bead to help with this problem. Trim about 8" and then center over the hole. Doug

    bead

    trimming the bead of the tire is pretty common, make sure you get a wide enough section to cover the normal turning of the tires.

    4" isn't all that uncommon, especially if you're dead hooking the tire.

    Also, if you have the dual valvestem set up, the valvestem might not be located correctly between the bead and the liner.

    The Hoosier liners are easier in that they have bigger grooves in the side to let the air through.
