Well, had the Battlax 023 on but I must say...never again. The seemed to lasting well and just before going up to France, I checked the tread and they sure looked good to me; I checked the depth and the minimum anywhere was 3mm ...so off I went!Can't get the Avon Storm here so going for the Bridgestone Battlax 023 which are getting rave reviews at the moment. Having them fitted next week so I'll let you know how they handle.
400 miles later I was sat in France trying to get a new set of tyres. The bike shop I finally found said that the 023 has a tendency to last well but to suddenly go...virtually overnight. Both front and back tyres wore down at the same time and very, very quickly. Probably not a problem if you are at home but who the hell wants to put new tyres on for holidays when you still have over 3mm on 'em? Although they did last for 5500 miles, I didn't like the way the last 3mm vanishes as if I had taken a grinder to them.
Anyway, the shop in France recommended the Battlax BT020 so I have those on now. Done 3500 miles on them so far and they still look good.
