Here's one I bet you don't get everyday:
I want to put dirt-track capable tires on a '98 Sportster. On the front I've got a 19x2.5 with a Dunlop K180. My question is, what's best for the rear... 17 or 18 inch? I've got a new stock rear hub ready to go so I can go either way. Doesn't need to be super wide, but how wide a rim can I use with the stock belt drive?
With the bias front tire I don't want a radial rear, so I think that rules out most of the 17" tires. Also, I want to stay with DOT-legal tires. Any suggestions?
