A shop usually charges around $80 per tire swap if you roll the bike into the shop. If just the wheel is brought in, the price is reduced to $40.
If you need to get your tires changed around NYC/Northern Jersey area, I can swap each tire for $25 flat. We remove the ugly balance weights and instead insert balance pellets into your tire, which balance the wheel on the go. Our group started using them at the beginning of last season. Since then, the pellets have been working without issues during two track days and the entire season flew by flawlessly. 90 degree air valve swap also available for extra cost. PM me for more info.
