    flatspotted tires

    *%$*%*$*%^&%!!!! I let my Z sit for about 5 months and now on the highway it wants to JUMP off the road. These are brand new yokohamas. Do you think that this problem will drive off the more i break them in or should i buy a new set of tires?

    and do some burnouts to get some heat in them

    A few heat cycles will tend to make them come back a little.

    Also, if you have access to a balancer you should recheck them. Sometimes the balance will go out as a tire wears.

    we flatspotted a set bad on a rental Mini-S in vegas. Something about large e-brake burnouts…

    really bad "thumps" and a bit of hopping… I could see the spots in the tires.

    had them rotated at a tire shop, took it behind a nearby business, and burned them off a good bit… mostly to heat them, and try to take the edges off so that they're more round for the return. Wasn't perfect, but was QUITE a bit bitter.

    btw, vegas locals LOVE it when you're assing a rental around. ;D Free rotation, thumbs up from anybody who saw it.
    vg33et -blew some chunks outta it, then gave it all away.

    It should go away. Overinflate them for a while, and do some "fun" driving including hard cornering. I have had tires sitting longer than that return to normal.

    Try about 10psi over normal and then get the tires hot. Be sure to return to normal pressure afterwards.

    Yeah I had 2 Yokohama's that had pretty bad flat spots. Some tard (previous owner) decided to burn out excessively then stop dead and the tires cooled to a nice flat spot. I just burned them some and drove around a little while with roughly stock tire pressure and after ~a month or so I seem to have extinguished any signs of flat spots.
