thank you for your replies everyone......
someone recommnded that I replace them with Mastercraft tires.
Are the Mastercrafts good?
Not hearing what your particular use is for the car, I'm not sure that changing the tires is necessarily the answer.
If you haven't been regularly rotating tires and checking alignment, the best of tires will fail similarly.
If you did rotate and align tires and suspension, at the dealer, or otherwise and can document it, it's likely you can get some kind of settlement with dealer.
Failing that, get your car aligned, plan on rotating tires according to manual/tire manufacturer, and get pretty much any tire that meets your budget...they're all better than tires have ever been.
Go to TireRack.com and check out the ratings, in the type of driving you expect to do.
I'll bet you a beer, that you'll have a hard time beating the Geolanders as a do everything compromise tire, except maybe the price, they are a little expensive...
