View Full Version : Tire expansion

27th November 2005, 22:03
Since my bike is rigid I'm going to lower my rear fender. I was just wondering how much room I should leave for tire expansion on a stock 130/90R16.

I would think that that is a real tough question to answer. I would think that tires from different manufacturers, and maybe even models from the same manufacturer, may be made with differing materials. Also, do motorcycle tires deform at speed simular to racing slicks or are they too hard? I'd be interested to learn the answer to this post.

From what i've seen 3/4"- 1" should be plenty. Then again i have
seen some fenders within a 1/2" and still work fine.
