WEL Posted December 22, 2007 Share Posted December 22, 2007 My car is currently fitted with 185 / 70 x 13 tyres (Avon CR322), and I have just acquired a set of wheels with CR500 175 / 55 x 13 tyres. My question is; When I fit these tyres will I have to raise the height of the car to allow for the lower tyre profile 🤔  Thanks Gary LADS website  WANTED - hood bag and Q/R s/wheel boss Edited by - w21sby on 22 Dec 2007 18:15:17 Link to comment Share on other sites More sharing options...
F355GTS Posted December 22, 2007 Share Posted December 22, 2007 Gary that is quite a difference, it will drop ride height by around 33mm so I'd say yes you need to adjust.  Note also that your speedo will over read. You will also be changing the gearing a bit resulting in slightly quicker acceleration but lower top speed and lower speeds vs revs in each gear Mark Link to comment Share on other sites More sharing options...
