I know a TIRE SCAM when I see one!
Take this scenario: I purchase 4 new 60,000 miles $200 each tires. I don't get back right away to the tire store, Discount Tire, to have my tires rotated and I had put on 6000+ on the tires already. Being that the tires on the front of ANY vehicle wear it tires the greatest in the front and especially on the right front. I needed to take my vehicle in to have the tires rotated to get longer life and a more balanced wear on all four. But after getting to Discount Tire the manager says, "Because your front tires are more wore than your rear tires we can't put the rear tires on the front. Or policy is to always have the better tires on the rear. To rotate the tires you'll need to purchase two new tires to be placed on the rear and rotate the rear to the front. I state, "But I've put less than ten thousand miles on these 60,000 mile tires and that's the reason I need to rotate them to the rear, so they'll last longer, because if I leave them on the front they'll wear their edges to the belt." Manager says, "I'm sorry but we can't put the more wore tires on the rear." I said, "Then I'll need to go someplace else, because the next time I come in you'll demand I buy two more new tires."
This is a scam! You could never purchase four new tires without uneven wear on the front and at that point they'll refuse to rotate the front to the rear. They're doing this to sell more tires. Be it's both the manufactures and tire stores, be it Discount Tire, Big O or many others, which are in on the scam.
