Guest matts206 Posted February 28, 2009 The general rule when putting wider tyres on is if you go wider you need to reduce the profile to compensate, because you will be changing the gear ratios. ie: 185/55/15 - 195/50/15 Share this post Link to post Share on other sites

Could you elaborate on that a little? Just had a coffee and woke up. Makes perfect sense. 55% of 185= 101.75 50% of 195= 97.5 Got you Edited February 28, 2009 by jimistdt Share this post Link to post Share on other sites
