If they rate Bridgestone and Metzeler the same than theres something wrong with there testing. Especially if they rate Dunlop and Michelin last.I saw an interesting article at the German Motorrad Magazine website regarding sport touring tires. Using the clunky Google Translate software, the website evaluated six tires: Bridgestone T-30, Continental Road Attack 2, Dunlop Roadsmart 2, Metzeler Roadtec Z8, Michelin Pilot Road 3 and the Pirelli Angel GT. The Pirelli came in first at 222 points and the Bridgestone and Metzelers came in at 215 points. The Continental, Dunlop and Michelin came in at 212 points. Test done last May 2013.
Perhaps in the translation you missed that the lower the points the better the tire?
