I just found a pair of 'tubeless' Avon 2.50 x 17 Streetrunner tires on my doorstep.
Oh, yeah. Ordered from Denniskirk a few nights back. Almost forgot.
I wore out a pair of michelin 2.75 x 17 m29s tires on my Newport. It took a few years. Very nice tires. No longer available. These Avons look very very nice.
But I'd love to go tubeless if possible. And I'd like to keep the OEM spokes.
Lots of feedback on the web. Mostly successful! ...for instance
Last time my tire went flat I said fuck it, I'm not gonna patch this, and just squeezed in a bottle of Slime out in the walmarts parking lot.
That was two years ago. Yeah. Not for tubes. But it eventually gets beyond the hole in the tube, out to the bead, and seals the stem and nipples. Two years flat free. Takes time, messy, but it finally works. So why not just cut the middleman and seal the inside well of the rim?
wire brush it. solvent clean it. coat with black rtv. secure the whole thing with a huge rubber band cut from a 16 inch (or smaller) inner tube. Maybe even a little slime before filling just for good measure. (edited)
