I've been using Metzeler ME33/ME99, and now Metzeler Lasertec tires for the last 20 years, and if you live in a region that has mild winters, and no wet weather ( think Phoenix), they are good tires. They need a good warm up before you ask them to get serious about cornering in temps below 45 F., wet weather is not overly confidence inspiring , but my OEM brakes are pretty bad in wet conditions, so I try not to get caught in any serious wet riding. But they stick like Velcro in hot weather. Average mileage is 8-9,000 miles on a rear, and 10-13,000 on a front. But they are pricey compared to other popular tires.
