06 2.0 Tyre Sizes - Ikethetyke
I have 195/60/R15 tyres on my estate and need to fit winter tyres this winter. Will I have any problems if I fit 195/65/R15 size tyres?

The rolling radius of the tyre will be slightly larger and therefore your speedo will under read slightly - you will get a ratio error of 3.17% . eg, an indicated speed of 60 becomes 61.9 mph.

One of the many tyre size calulators available:-

www.tyretraders.com/Tyrecalculator/

will give you more detailed information.

Make sure there are no insurance complications by fitting different sized tyres. Is the 195/65/R15 an alternate approved size recommended by Ford for instance?

Many thanks Dave. I take it there's no problems with the actual physical size of the tyres.
