It may very well be, but didn‘t a couple, including the PR5GT, and I think the Angel GT II, specs allow for up to 203mm, while the Bridgestones were over a full cm narrower, with a size 190 that was actually about 190? Has BMW ever published a specified width, other than the tire size itself?One thing to keep in mind is that the tires that have rubbed have been significantly over the specified width. I think this is a tire problem, not a BMW problem.
I thought guys here supposedly in the know debunked my first thought, which was a 190 tire ought to be about 190, and if your 190 is over 200 (or exactly 200, in my case), it’s out of spec. by definition, and the rest didn’t matter, so either they designed a tire too wide for the bike, or they mis-manufactured a batch of tires, but either way it was clearly the tire companies’ goof.
And some of those who would seem to know more than me indicated it wasn’t remotely that simple, so....???
