supraszr Posted June 3, 2009 Share Posted June 3, 2009 If I change my rear tyres from a 275/35/R18 to a 265/35/R18 is that a problem at all or is this OK? My fronts ar 245/40/R18 if that makes a difference in any way. Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted June 3, 2009 Share Posted June 3, 2009 No, it wont make any difference at all. Quote Link to comment Share on other sites More sharing options...
supraszr Posted June 3, 2009 Author Share Posted June 3, 2009 Cheers mate Its just 265's are cheaper so thought I would be better to go for that! Quote Link to comment Share on other sites More sharing options...
MrRalphMan Posted June 3, 2009 Share Posted June 3, 2009 Will make a slight change to the speedo reading as the rolling diameter will be different, but not by much. Quote Link to comment Share on other sites More sharing options...
supraszr Posted June 15, 2009 Author Share Posted June 15, 2009 Just a quick one if I change to 265 width should I change the aspect ratio? Quote Link to comment Share on other sites More sharing options...
paul mac Posted June 15, 2009 Share Posted June 15, 2009 Just a quick one if I change to 265 width should I change the aspect ratio? no, thats only if you change the diameter Quote Link to comment Share on other sites More sharing options...
James Posted June 15, 2009 Share Posted June 15, 2009 An aspect ratio of 35 on both the 265 and the 275 will be different from each other in size of sidewall as it's 35% of the width Quote Link to comment Share on other sites More sharing options...
pistonbroke Posted June 15, 2009 Share Posted June 15, 2009 you may want to go up to 40 profile to keep it the same as the 275. Quote Link to comment Share on other sites More sharing options...

paul mac Posted June 15, 2009 Share Posted June 15, 2009 you may want to go up to 40 profile to keep it the same as the 275. 265 to 275 will give about a 1% change which is a nats knacker, going to a 40 profile will put it nearly 3% out, 265 to 275 makes virtually no difference Quote Link to comment Share on other sites More sharing options...
