For you guys that mount your own tires on other bikes besides Wings... have you ever run across a set of tires that you couldn't get the bead to set?
* What did you discover the problem was, and...
* How did you solve the problem?
Here's what I've got:
I'm trying to mount a pair of off-road Continental TKC 80 tubeless tires on a brand new set of BMW spoke-wheels for an R1200GS. And yes, I said SPOKE wheels. The BMW spoke wheels are made for tubeless tires by lacing the wheel to the outside edge of the rim. You can see the tire & type wheel in the picture below:
Mounting the tires was simple enough, and I'm using a Craftsman 30 gal compressor set at 90psi to inflate them... as I've used successfully on at least 20 other sets of tires.
But for some reason, I just can't get these babies to seal. I can't even get the bead to set good enough to get 15 lbs of pressure in them. I've run my hand all over & under the tire while trying to inflate it, and can't feel any significant air leaks. I've tried using 2 ratchet straps across the tires at the 12 & 9 o'clock and 3 & 9 o'clock positions. I've tried different valve cores. All to no avail.
As of now, I'm out of ideas... except to break down and take them to a garage with a higher, commercial grade compressor.
Any other ideas?
