When I owned my RSV, [it weighted close to 900 lbs.] and used bias tires,Dunlop had just introduced a new bias tire ,the Elite III to replace their older series Elite II.So due to the short mileage I was getting out of the original Dunlops that came on the bike,[I forget which model they were] I tried a set of E III's. Well,not only was the E III a better handling tire,but believe it or not,I was getting 25,000 miles out of both front and rear tires,which was unheard of.Now that I have the Tbird,[820 lbs.] which uses radial tires like most bikes do today,the best I could get out of the factory Metzlers was 6-7000 miles,which,IMO,is totally unacceptable.And my understanding is,most of the guys with this model bike were only getting 4000 miles out of their tires,so I wasn't doing too bad compared to them.But I went shopping anyways,and after trying a number of different brand tires,I finally came up with the Avon Cobra AV71 for the front,and Dunlops new American Elite for the rear.Now I'm getting 15-20,000 miles out of the front tire,and 12-15,000 out of the rear,instead of 6-7000.So my point is,ya might wanna try a set of these tires.And the other thing I learned is,the recommended tire pressures may be TOO HIGH for your application,[unless you like to play squirrel or run on the race track,lol ] which wears em out prematurely in the middle.So I also played with pressures until I found a pressure that worked best for my application which was 4-5 lbs. LESS,then the factories recommended pressures,and the bike handles just fine. Dave!!!
