I had two sets of the Mettzlers. They handled great until they had about 9k then started to get loud. Had to change at 11.5k. Went to the Dunlop E-4 and was not impressed. Now my first set of the new Avons have about 500 miles. Stick nice, roll nice so far. And I bought a Jaco gauge for my compressor...try to better stay at the 40 front, 42 rear to get some longer life.
