Mounting a tubeless tire can be a *****, they are extremely tight fitting which is necessary to make a solid seal against the rim, but in the mean time you're cussing like a Marine. Then you have to have a special pump designed for tubeless tires, because you need a blast of air to seat the bead onto the rim.

Now you can begin to see that a tubeless set up is more expensive, the tires and wheels are more expensive, you have to buy sealant, you have to buy a special pump, money money money.

Going tubeless means, you may need to carry extra sealant, tubeless plugs, a sewing kit, super glue, and a high-volume pump to repair a large puncture or sidewall tear. You’ll also need a spare tube or two in case you can’t make the tire airtight after making the repair. All of this gear adds weight and costs. Things to consider if you are considering to go tubeless.

A lot of other forums I've been on some people who have gone tubeless are quietly switching back.
