Michelin Premacy 'green' fitted at new (April 2008). They lasted 28000 miles rotating them to the 1.6mm legal limit. I achieved a guaranteed ( nerd , I book every fuel fill-up etc not just relying on the computer readouts) 48.8 mpg on mixed driving. I fitted 4 x Barum Bravuris 2 and am just about to replace the 2 front ones after another 13000 miles (the rear ones are only half worn down). No 'rotating' done this time. I achieved 49.5 mpg over this period. No noticeable difference in noise or performance in dry or wet and at half the price of the Michelins ( not risking a puncture on expensive tyres !). Anyone got any views ?
