We all have the old yard equipment that has tubeless tires that are hard to seat the tires.

The bobcat as well.

We had used permatex aviation sealer as it was handy but messy.

Last weekend we forgot to check air pressure in bobcat and spun the rim in the tire.

The tire simply does not push against the rim to keep the air inside to seat.

On the shelf is a can of scotch spray adhesive contact cement...why not?

Easy, push tire back and spray between tire and rim to leave dripping coat and wait until set.

Pull tire and the stuff grabs, apply air and done.

Magic tire spray.

Not for the faint of heart, but starting fluid , a dismounted tire, and a spark will re-bead a broken beaded tire very quickly

I have seen (and heard) it done this way with propane and a oxygen/acetylene torch on a large backhoe rear tire. Raises the adrenaline levels.
 
Some my clients have a small tank about size of BBQ bottle with a 2 inch ball valve and wide flare shaped nozzle.

Fill to 100 psi, place in tire bead area open and go.

Works on many.

The black sticky goo with a brush works but it requires using the brush...gets on you 2 and hard to clean off, we like the spray much better.

Cheeta tank is one name. That is how most big truck tires are mounted on the road, slick as snot.

I wager you’ll learn a new language when you start to change that tire. That contact cement is some good stuff. Just a little food for thought. :bawling:

For true!

In a former life, I managed a tire shop. Some of our most profitable work was repairing tires and wheels damaged by field-expedient attempts. Suggestions as to using off-label adhesives are likely to either ruin the bead area on a very expensive tire, damage the wheel sealing area and/or make it impossible to change the tire by normal means. Specialty equipment wheels are ruinously expensive to replace and just hugely expensive and time consuming to send out to be sandblasted and powder-coated to repair damage from chemicals, adhesives and even the snake-oil-flat-fix-in-a-can.

Most tire-to-wheel sealing problems require dismounting the tire, cleaning the tire bead seating area of the wheel with a rotary wire brush, filing any nicks and repainting with epoxy. If a tire bead has a small gouge which is causing a leak, most tire shops have a rubber repair kit which is allowed to dry before installation.

Last weekend we forgot to check air pressure in bobcat and spun the rim in the tire. . . . The tire simply does not push against the rim to keep the air inside to seat.

FWIW, here's a non-destructive field expedient which does work on all size tires. Where equipment is operated, there are usually service trucks or hauling trucks with ratchet strap tie-downs. Put a tie-down around the circumference of the tire and crank down the ratchet to pull the strap tight. This constricts the diameter and pushes the tire beads out against the wheel bead seating area. I've inflated tubeless tires from 6" to 60" using this method.
