Turismo Todd

Hi Gareth, Excuse my ignorance but I thought rolling diameter was the size of the tyre IE 17in? I'm looking to change from 225 50 17 to 225 45 17.

Hi Trev, thanks for the reply. Appreciate that dropping the profile could potentially reduce ride comfort especially with our roads!!!!! however my previous two cars (none Audi's) had 45's or 35's and both were fine. From a personal prospective I just don't like the look of the 50's and I'm hoping to improve the look with changing to the 45's, again just my personal choice. Rolling diameter staying the same as is the width. Todd..

Currently running with "225 50 17" but was wondering if I could drop the profile size down to "45" without affecting any of the electronics like the ABS sensors for example? Thanks in advance...
