But I agree - the tyre size will affect the TDM dial and Bike clock, by ~2% per 5mm difference. The figures all seem pretty close to me.

I think my TDM may be over estimating, at least based on milage. I went to see my mum last Thursday - 208mlie round trip on the TDM. My wife went to see her mum on Friday - 198 mile round trip in the car. And HER mum lives a mile further past my mum! Perhaps I'll follow Edman's example and fit a few more speedo's.<!--QuoteEnd--><!--QuoteEEnd-->
Ermmmm.......thats my point Doc - and bring the bike and pushbike speedo up to the real GPS reading...............
