Tyre rotation, why should I do it?
This customary rambling introduction can safely be ignored. Jump to bold text and below. Video to drop in a few days. Most vehicle tyres tend to wear at different rates and bicycles are no different. Front tyres tend to outlive rears by a significant margin due to two main factors: 1. Gradual steady wear due to the rear being a drive wheel, so any acceleration produces a small amount of abrasion, the greater the change in acceleration the higher the rate of wear. 2. Weight transfer in braking. Both accelerating and braking produce abrasion at the surface of a tyre due to friction between the tyre and road. The greater the forces involved (hard braking, sprinting acceleration) and hence the greater the difference between the limit of tyre adhesion and the rate of acceleration or deceleration, the more slip will occur between the tyre and road surface. An extreme example is when one locks up a rear brake causing the bike to skid and paint a black line on the road. This can produce
