So im a hardcore noob and I bought these track tires from a guy that said the 180's would fit on my zx6r, so i got them put on. I rode with them for about 100km and i just found out that the chain is rubbing against my tire bc i can hear a noise and also i see the burnt marks on the side of the tire. My question is, can my mechanic somehow move the sprocket and chain a couple of mm away from the tire?? If yes what do i need to buy? or should i just find smaller tires and its totally not worth for me to keep these on?
