Metzeler Tourance Next

Once again from the States I write about the Metzeler Tourace NEXT. I've used two sets of these tyres for 12,000 miles, and while they have many good points, they also come with the "Metzeler Curse" in that they don't give you good mileage. My first impressions are they ride very smoothly and are quiet, the handle very well in wet, dry, and off road mud and gravel conditions. My application is the 2014 BMW R1200RT-LC, and loaded with a top case. If my stuff doesn't fit in one of my cases, it don't go. I've learned that the best starting point in regarding to tyre pressure for most dual sport tyres is 32 PSI front and 26 PSI rear, and after 2-3,00 miles I can get an idea if the tyre pressure needs adjusting either up or down, with the NEXT tyre at 26 PSI in the rear is perfect, but the front needed to be lowered to 26 PSI to optimize tread life. If you ride harder, or load heavyer than me then don't expect to get the same 6,000 miles I did. to optimize tyre life at these pressures the tread was wore down to the tread wear bars on the centre, and shoulders, and I've never had a tyre wear out this fast before. Other Dual Sport tyres at 6,000 miles have enough tread left to go another 2,000 miles before replacement.
