Another one I forgot - Big O Tires. I will never spend another penny with that company. Bought a set of tires for my truck, thing bounced around like the tires were square. Took it back multiple times for rebalance, no fix, after calls to their corporate office and several trips back to the store to rectify the situation - nothing. Junk tires were not round (concentric with the rims) the left rear was at least 1/2 inch out. I endured it for as long as I could (not a rich man) When I replaced them with Pirelli's . . . smooth as glass. BTW the Pirellis dry rotted and fell apart at about half the tread life, wont be buying those again either.
