Tough to be consistent on that one.

You can only figure it out when you've worn the tyre out - whenever you define that to be, my rear Tourance is down to the wear blocks in the centre, but they're staying on for a bit until my E-09's turn up (had a voicemail from Gwyn at Trellesport earlier saying they're on their way, woop) and I can be arsed to get them on - in which time I'll have probably increased their 'life' by 10% (currently ~5600 miles).

'Life' is also only even vaguely comparable either for multiple tyres with the same rider, or if you know the rider. For example I know I ride like a complete wuss compared to Tom , so I would take his 'Life' as a minimum to expect. Conversely I was talking to someone at an East Mids TRF meet the other month who said he'd had a five figure mileage out of a pair of TKC80's on an F650GS (the 800cc twin one). I resisted the urge to ask whether the bike was actually on a trailer for most of that distance.


Anyway, what with being a 'steadier rider', maybe I'll have to try a pair if I can't live with the life of the E09s.
