Foam for cart tires

[ultrarunner]

The tire dealer I trade with offers onsite foam filling... they do everything from hand trucks to large graders.

Price is based on weight... small tire small price.

If you don't like your rims! I've used it & it does work, but makes a heck of a mess if you need to remove the tire later on. Also, some brands rust the rims really bad! My JD 420 had some type of "hydro-seal" in the front tires when I bought it, had a pencil sized hole in one rim because of the sealant:

Why you put foam and such in a tube!!! so that when you have to remove it yea you have to cut the tire off with a sazal but once through the tube it should just peel right off in theory.

i so wanted to use "great stuff" closed cell foam that comes in a can at local hardware stores, when i had to replace both tubes in tractor over the last week. after checking the foam is not strong enough for a tractor. on other hand, it is strong enough for wheel barrow tires, and small size little garden carts that might go behind a small size riding lawn mower.

foam for actual tractor tires, is rather $$$ that will support the weight of the tractor. but the great stuff in red can, for the small little things from what i have read works good for the small light weight stuff.

If you'll read my post, it was in response to the post about "Ultra-seal", not foam! And yes, I have used Ultra-seal from Gempler's. ~~ Lowell

I still would use that stuff in tubes!! i know some is not rated for tubes but i have some slime on order and am going to be putting it in my tubes. Granted i already have tubes but if i didnt i think i would tube before i put goop into my tire. But just me.

We used the high density/?cold closed cell? type of foam (related to that "Great Stuff" but different) in a variety of smaller load tires, up to about 100#.

Or you could try these:
Closed Cell Foam Handtruck Tire

Or these:
Tire Blocks Run Flat System

...... these?
Low Duty Cycle Foam Tires - Amerityre Corporation

Last one:
Flat Free Tires

Now I know that these are probably more expensive than you want right now, but if the other methods fail, at least the links are all in one place where you can find them.

BTW, for the bigger vermont cart tires, try Northern Tool butvyou have to watch for either a good sale or a free shipping deal, but I have found their wheel and tire units to be very sturdy and serviceable even when I (often) load them past their rated capacity.

Oops, I lied, there is this too:
Urethane Foam , Expanding Marine Polyurethane Foam

I think one of the big downsides is the ride gets a lot rougher right? I asked around last year as thought of doing the same but many reported rougher ride on equipment when using foam as it's stiffer.

There are different density of foam available...

You are right in that just about anything is firmer than air.
