Marathon Industries Marathon 4.80/4.00-8" Replacement Inner Tube

Fit good, seems like a relatively decent tube, not very thin like some others I've tried.

Exactly as described

Worked great

Fits my little yard trailer just fine.

I gave this 5 stars because it seemed to be of good quality and held air. However, be warned. Rather then replacing the TUBELESS front tire on my 20yo John Deere STX38 I decided to just stick this tube inside the tire. It theory this works however, and this is the second tractor I've experienced this with with tubeless tires, the wheels NEVER have the valve hole in the right place for a tube valve. So the tube valve took a bit of a beating trying to hold it in place while wrestling the tire back on the wheel. It's not where the leak started though only after two mowing's. I didn't realize I damaged the tire BEAD while prying the tire back on the wheel. The tire bead has steel wires in it for rigidity and one of those little steel wires poked out, and into my new tube. FLAT. So, I didn't realize this until taking the tire off the rim again just now. I assumed it was the valve that I beat up which leaked. This time I bought the tube with the bent metal valve. I had already bought it and was replacing it when I realized I originally damaged the tire bead. So, I'll copy and paste this review on the new tube I bought. Hopefully this new tube will last longer. If it doesn't, NOT the tubes fault. Next time I will just buy a new tubeless tire and a new valve. Hopefully, I didn't bend up the wheel too much for the new beads to seat.

My wheelbarrow tire was originally tubeless but after many years of use, it wouldn't hold air longer than a day or so. Installing the tube was kind of a hassle, but I'm thinking it was more me not having the proper tools. After I got the tube installed and filled to the correct pressure, haven't had a bit of problem with the wheel going flat since. Well worth the time and money.

Was used on a log splitter tire. Tire was rated for road worthy (but never is used on the road) on a 4.8 x 8 size. It "fit" and worked fine other than there was no easy way to get the stem to stay out or lock in. This would have helped and made the product better if it semi locked into the rim,especially for installation. The stem kept moving around when trying to put the material in the tire. Once some air goes out then its going to get sucked back into the rim as i had to hold it out once trying to fill it with air initially. It seemed like it would work better on a wheel barrow or taller type of tire. There just seemed like a lot of material for a 4.8 x 8 tire. Once it was inflated and in it sealed the old tire just fine and held great for the last couple weeks.

Pretty strong tube which took a little manipulating to get it inside the rim with the tire half off, though the tire may be as much to blame, being fairly rigid and knobly. It’s still fully inflated after a month. Be careful not to use sharp or even semi-pointed tools to assist in inserting the tube. I used brute force, a wooden spatula and lots of grease…the elbow kind.
