Since Feb 2010: 17,500 miles (Mostly a 200 mile commute twice a week)
Tourance EXP: Front: 6,000 (did have more life in it)
Rear: 6,000 (Very squared off, handling reduced, especially in the wet)
Overall: Tyre is very stable but is made of cheese when it comes down to wear rate.
I did buy another set (Tourance EXP) which lasted a little longer until 14,000 miles.
Michelin Pilot Road: Front: 3,500 (still on the bike)
Rear: 2,800 (Puncture on the A47; Balderstons changed the tyre in less than 15 minutes, awesome service)
Overall: Very good in the dry and wet, although not as much grip on overbanding and white lines as the Tourance; wear rate was much better on the rear. I would recommend for motorway commutes)
Bridgestone BattleWing: 1000 miles, in good condition have had some twitches on the back end on overbanding but I do have this mixed with a Pilot Road on the front. Now I have to decide if mixing tyres is bad or good???
