Tyres were fitted in April 2014 and the price at that time was comparable with other makes. Tyres fitted to ST1100W, UK bike. Both front and rear were worn to 1 mm in 7500 miles. Also both were badly squared off. I put the squared off wear to the two up plus luggage long jaunts. Bike probably around 500 kg for hours and hours of autoroute/motorway miles. Despite wear type and low tread the tyres performed well albeit it tipped into bends a little too sharply for comfort. Wet weather grip is excellent. Just fitted another pair, fitted to the bike for £220. Not cheap but good.
