Just hitting 15,500 miles and have worn out my second set of front tires. (also on my second rear tire too)
The first set of Avon tires, the factory set of tires worn out the quickest and had a very soft sidewalls.
This second set of tires has been from Blockley which lasted longer and had a stronger sidewall over the Factory
I'm going to try the Coker Excelsior tire now.
I'll let you know how the Excelsior work out.
