I just dropped a grand on 4 new tires and had serious problems with two of them over the weekend, at the same time. They sent someone to change the rear tire and put on the spare. Not entirely helpful because one doesn't routinely carry two spare tires. I had to pay a tow fee of $55 when their mechanics left me stranded on the side of the road. Their saving grace so far is; the gentleman I spoke with on the phone, hooked me up with a loaner car to drive until we can address this Monday morning. I will save my final opinion and official review of Rocky's in Spanish Fork based on how they choose to remedy the situation. Really like Rocky, but, I've had the tires on for under two weeks and it is very disappointing to be facing a major problem already. Hope their warranty is as they stated when I made this purchase.
