I have an 06 sporty custom on average I get 12000 miles on front dunlops and about 20000 on rear, about a two front to one back ratio tire. there are only two companies of tires dunlop and michaline tires that have my size that I know of and they both get about the same milage per tire. especialy the front one it's a 21 inch tire. Is there any other brands that carries the size for an 06 custom sporster that might get better milage on use?
