I went to Discount tires today to buy the Ohtsu FP0612 A/S but got the Arizonian Silver Edition III instead. They were going to honor Discount Tire direct pricing on both tires. I got the TPS reset charge($20) waived. With all the rebates figured in the Arizonian Silver Edition III were $17.50 a tire more. I think I got a much better tire for not a lot more money. I got a total of $175 off what it should have been with all the rebates. My net cost is $281 for 4 tires. How do they make a profit?
