I've purchased from Discount Tire for over 10 years in Las Vegas and was stunned at this experience.
They tried to charge me over $800 bucks for four tires when three of them were damaged and under warranty by Discount and/or the factory (heat rot and tread splitting) . After a lot of probing questions and pushing the issue of the warranties my final bill was $500 which was still too much.
I felt like I was in a shell game, bait and switch and mis-information campaign the whole time. I was slimed and will never go back and am telling everyone the same. Bummer.
