I've never had a tire wear out so fast! At only 1,800 miles the stock rear tire is about gone. I estimate it to have about 500 good miles left on it and then it will be sketchy. I will say I got great traction on the muddy dirt roads up here in Michigan and find them wholly adequate for my type of riding with the exception of wear. Any recommendations for a good 50 50 rear tire that will be compatible with the front stock Dunlop which seems to be wearing well and at least give the same off road grip as the Dunlop 750 yet wear at least twice as long?
