Anyone had any luck running these tubeless on suitable rims?

Yes…. On stock non tubeless 19mm internal width Alex Rims. Had to pack out the middle of the rim with a few wraps of gorilla tape (3 wraps) but popped up fine with a blast from ghetto tubeless inflator (no way they were going to seat with track pump).

Needed a little extra stans to seal the sidewall but lasted a good 6 months before I switched to the nano’s.

Edit… Mine were the folding (not wire bead). I have never had much luck with wire beaded tyres and tubeless setups. With a tubeless specific rim you may be alright.

As above I used the folding versions on some Alex rims (apparently tubeless compatible), weeped a bit of sealant from the sidewalls for the first few weeks but held up fine.
I only changed them as I had the 30c version and wanted a bigger volume tyre.

Yes. Running 559 wire beaded on Stans Crests on my frankencross. Took a while to seal, but have been flawless ever since. They are the only 559 cross tyre available, so I thought I’d have a go. Raced them at the SSCX championships earlier this year.
