Confusing at best. Spoke with my tyre dealer this morning and ordered the PR5 (with road tread on rear and front, the rear is road tyre, the front is trail tyre, pay attention at the back)
He said the Michelin is outselling the Metzler on GS's but both very good road tyres. Michelin may last longer but we all ride differently!
He said the Metzler profile is 'round' so consistent in the turn and the Michelin is profiled for a faster turn in.....I assume because of its a variable radius cross section???
Good grief!
But he is right about the Metz carcass shape vs Michelin. The Metz are similar to Dunlops which are very round and offer a very even rate of turn. Michelins have always been quite pointy so offer a fast drop in, but then feel very planted with a fat contact patch. My favorite remains Pirelli: they are half way between Metz and Michelin and are very predictable and confidence inspiring at varying degrees of lean.
