....................... I just finished mounting a tubeless Carlisle 20X10-8 for which I paid nearly $70 and which arrived in such a malformed condition that I couldn't set the bead myself. I had to take it 20 miles into town where the repairman had to use a "bead blaster" to make it happen...................
It will be a bitch to stretch over the rim but apart from that it will be fine.
The thing to watch is the valve does not pull back through the valve hole.
Tubeless rims have their valves around 1/3 the way up the side and tubes usually have the valve on the centre line
This means that the tube will be twisted sideways and will try to pull back into the tyre as it gets inflated till the pressure pushes it out.
Thus it is a good idea to slip a nut on the valve before you inflate the tyre.
