I really hate to post this but I need some direction. I've only run the OEM Scorpions since I bought the bike in March this year. There are a million threads on the subject but I cant seem to find a definitive (objective) thread on tire comparison. I ride 60/40 street/dirt and ride the bike to work 2 or 3 times a week. My commute is about 80 miles round trip and I can take twisties or highway. I was really leaning towards the TKC80's but now I'm thinking MEFO Super Explorer's for the mileage. As I understand it, either will be an improvement over the Scorpions off road. I don't ride the wild and wooly with the 990 (I have a 300XCW(e) for that) but I do want to ride more than the NFS roads and Jeep trails that I have been. Suspension has been done, bash plate, guards, side stand relocation all have been installed. ANYWAY, something I can reasonably expect to get 3-4 thousand miles out of, that aren't just rim protectors is what I'm looking for. Any help would be appreciated.
