I have maxxis supermax diamonds on mine, I get about 4,500 miles out of a rear, will be putting the 6th rear on soon, I find them better than the 020's that the bike came with and I replaced with 3 more rears, I put a new front on to 2 rears, you can't beat a new set of tyres, my bike has 44,500 miles on it, I changed the oil in the front forks last year and the brake fluid, greased the swingarm, hope to do the head bearings soon, but still handles like new.
