Hi fellas, well my tire problems continue. Back in may i bought a set of 305/55/r20 nitto grapplers from discount tire. Got em put on and they shook the crap out of my truck. Took it back, they found one tire bad. Too much rubber on one side. So they replaced it. I drove the truck some more and it still shakes only not as bad. Had to take the truck to les shwab for a diagnosis because I don't have a discount tire where I live. Low and behold, yet another tire was bad. They put the suspect tire on the road force machine and it measured 40lbs over the acceptable limit. So far, discount has been unwilling to work something out with me based on my location. I'm 8 hours from the closest discount tire. WHen I bought the tires, they assured me that if something was wrong, they would work something out. So far they haven't. My suggestion would be to stay local and stay with Les Shwab if you have one. At least they stand by their products. Stay away from Discount.
