:help:

My neighbor has a greenhouse operation grows and sells flowers mostly annuals.
He has about 40 shopping carts all have small air filled tires with tubes, 160 tires all together. Size 2.80/2.50-4 4ply max pressure 50lbs.
Problem too many flats and too much time repairing them.

Any body have any experience with foam filled tires, how to do it, what to use or solid tires and where to get them?

My cousin mows interstates & bought a foam filler. Takes special equipment & special foam. Not a cheap endeavor. He recycles by cutting worn tires off the rims, then using a sawzall to cut the foam from within the tires into chunks. When me mounts one bead of a new tire, he tosses in all the chunks, then fills the cavities. The foam isn't cheap. He pushes a LARGE needle into the top side of tire opposite valve stem & fills from bottom to top. When foam comes out the needle he's done. Tire rides good, almost as regular air/water mix, and weighs the same as plain water.

Here's a place with pricing guide. A 26x12x12 costs $66 for just ONE tire!

From what I've been able to find out you use a minimum expanding foam, remove the valve stem, drill a hole on the top of the tire and spray in the foam till it comes out the stem and the drilled hole???

Don't try household type foam. It won't hold up, then you'll have one mess to deal with.

I used to work at a tire shop in hagerstown md.We did foam filling for the local salvage yards.Just as was said cut the old tire into chunks mount 1 bead of the new tire stuff the chunks into the new tire until you can't get any more in,then mount the other bead ,air the tire up to seat the bead stand it up valve stem on bottom insert needle into the tire straight up from the valve stem then pump the liquid foam in until it comes out the needle.The tire needs to set for 24hours to cure before putting it to use.They sure are HEAVY!!!!!!!!
