[QUOTE="Tom Gaynor, post: 22326, member: 4034"] Somewhere in the literature it suggests that the speedo is more accurate with the 21" front wheel. Maybe. But 100 mph GPS is 103 speedo with my 20" front. I can live with that. And besides, what signifies is the rolling circumference of the wheel: it's got a flat at the bottom. Nothing wrong with the standard tyres from the POV of load carrying or longevity: except that tyres are no longer made from Bakelite, so give the same total lifetime grip as they always did - but over a lower mileage, if you see what I mean. But. My advice would be to use the 'net to see what tyres are easy to get, and use those. Little consolation to know that you were doing 30 mph +/- 3 % when the 20" front tyre, a size that is impossible to obtain within three weeks, wears out. I suspect you'd figured that already...
