I found a tire in my basement that I apparently purchased when I owned a BMW K1200LT and ST1100 (for a couple years I had both of them). It is an Avon Azaro AV36 160/70ZR17. That tire was made with extra construction for the weight of those two motorcycles only. I now have an ST1300 which uses the 170/60ZR17. I'm trying to decide if it would be ok on my ST1300. I realize the cross section width would be 10mm narrower, I'm not concerned about that, might actually improve the handling. My concern is the diameter, and whether it might interfere with something in the suspension or body of the ST1300.
The correct 170/60 tire has a nominal height above the rim of 170mm x 60% = 102mm. The tire I have has a nominal height of 160 x 70% = 112mm. That means the radius is 10mm greater. I don't think there is anything that close that would rub. Has anyone else ever tried this size on a ST1300? I searched the archives, found some discussion, but did not see notes that anyone actually did it.
