I currently have an Avon Venom 250/40/R18 on my 2004 Soft Tail Chopper. I was told that the Dunlop Elite 3 is not compatible (i.e. too big for my bike). I was also told that the Avon Cobra replaced the Venom of the same size. All a little confusing. I need to know what does fit as a replacement. Also, any pointers towards good deals for a new tire would be appreciated as well.
