I presume Edinburra's would be nearer to mine. But maybe not.
Sent from my iPhone so this is what Autocorrect thinks I mean.
The SSSW I have is the one recommended on the door card on my TT. I believe that the rolling circumference of all these recommended wheels/tyres is similar.
While I was test fitting the space saver spare I measured the circumferences. This was just a static measurement and not the true rolling circumference.
Against a 245/35 R19 93Y tyre, the circumference of the T125/70 R19 space saver is approx 10mm smaller.
If you look on web site http://www.kouki.co.uk/utilities/visual ... calculator this will help you see the rolling circumference of any wheel/tyre combination. For example the 125/70 R19 runs at 0.5% less than the 245/35 R19 meaning that at 30mph you will be doing 29.8mph. Checkit out for yourself it is an interesting tool.
