... Will they make much difference to handling or speedo readings? Thanks, David.
Thanks for your comment, this backs up what I had read. A lot of my driving is on poor ish B roads and I don't think wider tyres would help me. On track I am sure the extra grip would be great.I fitted 225 RE070 's onto pro race wheels which are 7j and a 45 offset. On a smooth decent road surface the car behaves perfectly, but on uneven bad surfaces it does tend to follow the camber of the road under hard acceleration. It's not too bad but it is noticeable,I think it's down to a combination of lower offset on the wheels, wider tyres and the diff working. I haven't noticed any difference in speedo readings.
