Also been looking at new feet for my little princess this week... actually I have been on the lookout for the past 12 months. I had really set my heart on white walls. I have given up on the wide band American style as they are soooo expensive in NZ.
Even the thin band 10mm European style are hard to get. Getting them in 195/75/R14 is proving a real challenge. I do however have a set of 205/75/14 available to me now and need to make a decision quickly in order to secure them. Would appreciate everyone's feedback on these.
I have run the calcs and other the width I am happy to take the rest of the differences. Even with this measurement its only 20mm wider that the original 185. If 20mm starts to cause interference issues then I will steer well clear. I would imagine that this would only happen on full lock in the front and can understand how this might touch the exhaust on the rear. The exhaust can however be tweaked to fix this. More the front end I am worried about.
In terms of the speedo the worst outcome is probably 1.4km measured speed difference at 100km/h. So what. Parallax error on the drivers part is probably more significant.
The only consideration is rubbing in my mind. Unless otherwise convinced I don't know if I believe the stories about significant damage to steering and suspension componentry due to excessive loading. We are only talking about a couple of percent variation on all of the dimensions.
I have been using the following site to quickly compare and contrast the different sizes relative to what shipped on the car back in 64.
