Or go all the way and fit a 15 tooth on the front as well,This saves nearley all Tyre wear on the front !!

I just put a 15 tooth sprocket on the front, i think its about equivalent to losing 2 teeth on the back, made loads of difference, didnt need to take the back wheel out and best of all cost just £10 new from my local bike shop.
Well worth considering.
