As for the return issues, I bought them from Les Schwab Tire. I already did one exchange with 305/50-20 AT's. Despite the fact that those were siped as well they let me return those and I got these MT's. I do a lot of business there and I'm not going to have them take these back as well. Besides, their policy is very specific when it comes to taking back siped tires. They don't. However, they let me do it once and I'm not sure I want to argue to make them do it again.
Besides, the AT's I want are either Nitto or BFG's and Les Schwab does not carry those in stock. My local Discount Tire store however does.
