The problem your having with the front tire seems to be fairly common with the Metz tires. I had it happen with my 08 and the tires that came on it. Low miles, less than 5,000 miles. The front became hard to control. A article I read at the time made sense. The Metz tires are made of a fairly hard rubber. The wear is not consistent because we ride much different due to conditions. Most newe tires are built with a hard center band. The sides are much more pliant. Having different rubber compounds allows for mileage increases more than 3 times from the Metz brand. My experience shows Michelin, Avon and Dunlop all make new generation tires. I’m running Elite 3s on my R3T, 2015. When I make a sweeping turn I can hear the tires change to a softer material. The tires grip much better in the twistes too.
