I know the question of rims on cars has been asked time and time again but I have another aspect to consider.

I have a 95' Golf GL and I have been looking around for some nice rims and these days all the good ones are 17" inch and up. So having done the calculations on the miata tyre calculator I will probably need to run 35 series tyres on 17" rims, which I am not keen on for a daily driver due to what I expect to be a pretty harsh ride. If I go to a 205/40 the diameter is up by 18mm from stock right. Which is a 3.2% increase. Is this going to make much of a difference. I had a friend who upgraded his rims and they put the speedo out a tuch but stuffed up the ABS in the process. Has anyone put the larger rims on and had this problem.

I guess 16" is probably a sweeter spot for the older cars but they are harder to find.

What have peoples experiences been should I hang out for some good 16"s or go for 17"s. I am planning on putting in coilovers to improve the handling in the near future too.

Cheers,
