Concerns with TKC's
My wife and I just returned from a trip to CO on the GS. I put a set of TKC's on the bike before the trip. About 2000 2-up highway miles and 100 miles offroad. When we got back, I put the Anakee's back on the bike. What I saw when I dismounted the TKC's should be alarming. The inside liner of the tire has a pattern design to it. About 1-1 1/2" of this pattern has come off all the way around the inside of the tire and has formed into a lot of little balls of rubber. This is an indication that the tire has overheated and is about to fail. I ran max pressure in the tires on the road (34) and never exceeded 75mph. The speed, pressure and weight of the bike 2-up should have been just fine with the TKC, but a few more miles and the rear tire would have failed. My wife only weighs 100# and the bags were not overloaded.
I have a German car repair shop and we have seen these little rubber balls a number of times in tires that were run underinflated and had either failed or were about to fail. The TKC was never run underinflated and I am reluctant to inflate a tire above the maximum pressure stated on the tire.
Be careful out there!
