2006,R12GS. Current mileage is 5520. Just completed the 6000 service for a trip. I used a tread depth gage on the tires, to see what kind of life I can expect. (I am new to BMW's and usually got 17-18000 miles on a Harley rear and 42-43000 on a front). I measured 4mm on the OEM front tourance and 6.5mm on the OEM rear. My Metzler book shows original tread depth of 5mm front and 9mm rear. By my math, I should expect 18,789 miles on my front and 16,331 mile on my rear.
Does this seem reasonable?
It does seem more than what I have read on this forum. Thanks. Max
