See if there is a used tire dealer in town
I know one around here that buys dealer take off's
In other words, a new car dealer wants to add aftermarket rims and tires to the vehicle, then the tire dealer has a new set of tires .... but he can't sell them as new - even if they only have 10 miles on them, they can't be sold as new
Might be worth checking out
My buddy bought some tires from him off a newer vehicle roll over /vehicle was totalled
they were just fine
