Flat Free Garden Cart Tire

Introduction: Flat Free Garden Cart Tire

About: I'm that guy from that place who built those things

I decided to try make some flat free tires for my garden cart. I was thinking about expanding foam but walking though a store I seen pool noodles.
I have 4.10/3.50-4 tires. I bought 2 jumbo pool noodles 3.3” diameter and 54” long.


Tires off a garden cart. 4.10/3.50-4 tires
2, jumbo pool noodles 3.3” diameter 54” long
Sharp knife
Ratchet set.
Optional- impact driver

Step 1: Remove Inner Tube

Unbolt the rim and separate.
Pull old inner tube out and discard

Step 2: Cut Pool Noodle in 27 Inch Length.

I cut the noodle in 27 inch lengths and cut a bevel on the end to make sure it will be slightly longer on outside most part.

Step 3: Stuff Noodle in Tire

I started suffering the noodle into the tire. This is fairly difficult and takes trial and error to get good body positioning.

(I had pictures of starting stuffing the tire but I accidentally deleted them)

Take the beveled end and stick it in to the tire and work your way around stuffing the noodle it.

Step 4: Trimming Length

The noodle should be longer then needed. I used a sharp knife and trimmed the noodle so it was about 1” or 1 1/2” longer. Then I stuffed it in, the the ends are butt into each other. I made sure the noodle was stuffed properly in the tire.

Step 5: Re Install the Rim.

The noodle pushes the sides of the tire out, I had to use a clamp to get the rim close enough to bolt. And tighten the bolts.

Step 6: I Tested My Body Weight on the Tire

I put majority of my body weight on the tire to see how much it would compress. I put over 200 lbs and the tire held up good then installed it on the cart and stood on the cart

It seems to hold up very well
