general problems of the 2004 GMC Sierra 1500

Tire separation.

I bought new GMC sierrra in mid 2004, truck equipped with goodyear wrangler st. Truck exhibits very poor wet traction and excessive tire wear. When tire was approximately at 18,000 miles had serious spin out on i75 south of tampa in lite rainy condition. Since then noticed tire spin on slightest wet roads, even has trouble pulling out of car washes. This is dangerous tire and should not be instilled on large vehicles. Tire is down to wear marks and only has 28000 miles. Tires have been rotated and maintained only by gm dealers. Goodyear dealer states this tire should not have been installed on full size trucks, it will wear excessively and may lead to blowout. Dealership won't do anything and goodyear states it is not covered by warranty because it was original equipment installed by manufacturer.

I purchased a new 2004 GMC in febuary 04 and it keeps wearing the front tires to excess and the dealer keeps telling me that's normal for a four wheel drive,,bull the tires are bridgestone dueler 265/r70/17 andthe truck. Is a 1500 GMC serria , I maintain my equipment and keep a close eye for problems and I can see someone who does not with tire failure and accidents, I have look at the same moldel and they too have the same problem with front tire wear.
