Change in rolling diameter, and effect on speedo.

[Indie]

I've just picked up a set of wheels with tyres, and the overall diameter is around an inch more. Will this cause any problems, and what effect will it have on the accuracy of my speedo? Cheers.

Awesome, thanks.

I'm also trying to learn the stock diameter. Did the DC4 come with 195/60 R14 as standard?

Personally id just stay within 2% of the stock tire. Increasing height will affect acceleration.
