You can't charge what a $tealer does, too many of us out there who've been changing tires for Years that offer it at lower prices. Gotta keep up with the person who's posting the cheapest prices if you expect to get anyone. I've owned a No-Mar for awhile now and do tires off-bike for $10 each and on-bike for $20 each. I can probably start charging a little more since I just moved to a very rural area without a local MC shop, but the trick now is getting people aware. You probably have someone who changes tires near you (and have for a decade) and just didn't know about it.
