240hp..? Wow! How did you manage that? And, how much torque accompanies that horsepower? Funny you should mention Avon Cobras. I just put a set on my R3T earlier this week, ( my first set of new tires, since buying my Rocket ). I only have 7,500 miles on my 2013 R3T, but my Metzeler 880 Marathons were shot. All "cupped" and stuff. Some folks have told me, the Avons won't give me high mileage either, before my next tire change. That's fine with me. The Metzeler 880 Marathons didn't give me much. Not even 8,000 miles. I'm confident, I'll have plenty of grip from my Avons, no matter how much, ( or how little mileage), they give me.
