I have a 2005 Sebring Convertible w/ 130K, 1 owner car in perfect condition and never driven in the snow. I bought a set of Discount Tire Ohtsu tires in 2014, put about 12,000 miles on them and they have a ton of wear. A shop in town has a set of used Premier A/S tires w/ about 7-8/32 of tread and they want $260 installed for the set. 2 of the tires have a plug/patch repair on the tread. Would this be a good deal? I plan on keeping this car forever since there are no longer family size convertibles on the market that can hold 2 sets of golf clubs. I want good tires but don't want to spend more than the value of my car to get them.
