If you put a tape of special polymer material with a low coefficient of friction and self-lubricating to fender inside in such a feeling.
The better the slip of the tire. it is an excellent thing tape will not say skinny.

Since you no longer caught in the tire it will feel like running even better ....
Also eliminates the rasping sound.

Basic (hard) is polyethylene tire only.
The feeling that you tried. but was okay to use the tire of polycarbonate such as other materials.
It is not intended to guarantee 100 percent protection.
(Hard) your use of the tire other than polyethylene. I am sorry. I need your help by self-responsibility
