    Default Cart tire experiment

    I have been utilizing a garden cart to tow behind ATV to carry my 15 gal spot sprayer. As always out here flat tires due to goat heads are a problem.

    The issue is any non auto/truck/tractor tire are at risk, particularly minions bicycles and the dirt bikes.

    There are ways to mitigate most but a few(usually due to size or specialty) fall into no man's land of no or very expensive mitigation.

    I have the original tubeless tires and wheels for the cart and decided to make my own "solid" no flat tires. Figured they need to carry at least 300# lbs each. I pulled the valve stems and used the "big gap" aerosol foam insulation to fill the tire completely.

    After letting them set up for a day and remounted to cart.

    Put the sprayer and battery to power it back into cart, filled the tank and took off. So far it works fine, tires hold shape and very little deflection on rough ground.

    No clue how long they will last but believe over time the rough impacts will cause foam to crush and tire to "go flat".

    Small spot where bead wasn't quite set.

    Makes stalagmitesCleaned up a little and this tire didn't fill perfect/complete. Was able to clean stem and reinstall valve and add a little air, no clue if will hold long term.

    When I worked at CDOT all of the small turf mowers had "foam filled" tires. We used JW Brewer Tire. I think it was about $25.00 per wheel.

    For Bicycle Tires, Specialized Brand Armadillos are the way too go. Thousands of miles, Thousands of goatheads, glass shards, etc...never a puncture

    Have been using cart couple times a week since filling. No noticeable breakdown or deflection of tires even when hauling full load of dirt or other heavy loads.

    That type of foam is not designed to be compressed repeatedly. Its designed to fill a fixed void. It will work in the short term but it will eventually break down due to being compressed. Depending on the frequency of use that may be good enough for your use case. A bottle of foam filler is a lot cheaper than specialized tires though so you may be ahead of the game.
