that much of an increase will be marginally better in performance handling. But at the same time be marginally worse in economy and more drag, which might even be an even move with the increase in diameter? i am talking small numbers here..

a 185/60r14 can be had for as little as $38 canadian from tires easy, but you should do more research into what you want as far as treadwear and such for performance.

(tires easy canada doesnt have as nice a selection as the us site)
