I really am shocked at how bad the stock IRC tires are...
When I rode a DP bike,... I swapped to an IRC tire that was much better than stock...
They aren't a bad company,.. that tire just ain't good on this bike...
It puzzles me...
Metzler's are good high mileage tire... they have very thick tread...
I hope you ride a lot... because that tread will go 20k + miles... the problem is twofold...
1. ...you need to burn up that tread before the compound dries out... 4 to 6 years...
2. ...tread that deep will wear a flatspot in the middle before it is used up... (that's okay, if you are primarily a highway commuter,... but, if you are a canyon carver... that flat spot will create a ridge to overcome on every right or left bank...
MC tires are not like car tires,.. they need to to keep an even transition from centerwall to sidewall... otherwise, you'll get that "lift, then fall" action when going into turns... with a low traction edge to overcome in every transition...
Bike tires always wear the center tread out first...
That said,.. Metz.. really are the premium high mileage tire...
Enjoy,... and ride yer' brains out... (not literally)...
