I put a 150/70-18 Metzeler ME880 tire on the rear of my 2000 Road Glide. I knew the tire was going to be close to the belt and it is. In fact it appears too close. A straight edge tells me I'm into the belt a good 1/8". The pulley I bought came with a 1/2" thick spacer for the pulley. My question is will the belt move 1/2" out on the trans pulley without a problem. A spacer only half as thick would of been perfect. Anyone run into this problem themselves?
