So I have a 2005 black CTS on 20s. Im about due for some new tires. Currently, I have Toyo Proxes 4 24535ZR20's on. My only complaint about these tires is I dont get much tread life out of them (around 25,000 miles) and I dont drive like an A$$. What tires can you guys recommend that will last a little while longer but dont cost an arm and a leg. Suggestions?
