Why do you need a Rim Lock? The rim lock stops the tire spinning on the rim under hard acceleration or braking, especially when the tire is being run at low pressure. If the tire was able to spin, it would rip the valve stem out of the inner tube along with a few other nasty issues.

Are rim locks important?

Since we ride motorcycles at low pressure compared to a car (8- 19 psi), the rim lock is necessary to provide sufficient force to the bead of the tire to prevent the tire from spinning on the rim. … When a rim lock fails to secure the tire to the rim, the valve stem is torn from the inner tube.

Does the rim band go over the rim lock?

We have always put the rim tape under the rimlock (using tubes). If its a tape it has to be under, if its a rubber band it has to be over.
