Clive Posted November 12, 2012 Share Posted November 12, 2012 155/80 13 stdfor a bit wider 165/70 13 or you should be OK with 175/70 13 Quote Link to comment Share on other sites More sharing options...
jamie31888 Posted November 12, 2012 Author Share Posted November 12, 2012 Thanks Clive!What would be the benefit of fitting the 165/70 or 175/70? Quote Link to comment Share on other sites More sharing options...
MarkB Posted November 12, 2012 Share Posted November 12, 2012 I have personally fitted 155 80, 165 70, 175 70, and 185 60 13" tyres on spitfires over the years. I think the only real advantage of the wider tyre is that they can look better. On standard wheels I would stick with 155's on a Mk3 or a bit wider on a Mk4 short shaft model. The narrower tyres avoid any problems with rubbing the rear arches or front wings, and on a road car I haven't noticed any benefit in handling with wider tyres fitted, only heavier steering.Mark Quote Link to comment Share on other sites More sharing options...
junkuser Posted November 12, 2012 Share Posted November 12, 2012 And greater loading on the vertical links when using large lock during low speed maneuvering. Quote Link to comment Share on other sites More sharing options...

James Posted November 13, 2012 Share Posted November 13, 2012 I used to have 145s on my Mk3 and it was great to drive!Who needs road holding when you have great handling?I remember the first RBRR I did in 2004 and there was so much standing water — never a chance of aqua planing.

Been there done that as well over the years and I've just about come full circle on this issue :X I've recently changed from 185/60-13 on the Spit 2.5 to 165/70-13 and I'm loving it :) I can actually park the thing now without tearing bicep muscles and no longer have to get all my fillings refitted after driving through Edinburgh ;D ;DIt's quite a powerful car for a Spit and I can detect a slight loss of traction but for normal road use it's virtually undetectable.We now use the Spit almost exclusively for road work and touring (which wasn't the original intention :B) and for that sort of use it's a much nicer car with the 165s on it.
