AR-PRO 4.80/4.00-8 Inner Tube, TR-13 Valve Stem, 2-Pack

Fit and work perfectly

Placed these inside dry-rotted cracked tires on a tiller. They were much easier to install than new tires on the rims, & at a fraction of the cost. The bent stems helped keep them in place while I tucked the tube around the rim inside the tires. (Putting a washer over the stem then replacing the cap didn't hurt, I'm sure.) So far so good.

fits old 14 x 4.5 - 6 tire perfectly on my MTD roto tiller. Plus you get 2 if you put a hole putting it on. Nice and thick durable tube so I have as spare for the other side.

One of the tubes arrived patched, but it seems to hold air fine and works as expected.

It’s been a long time since I’ve put a tube in a tire and I had limited tools with me. Got it in and put the air to it and the valve stem sucked into the tire. Other than that it is heavy duty and fits my application. If I ever need to get to the valve stem I’ll pull it in my shop and break the tire off the rim.

Worked as expected but be prepared to fight with those little wheels if you don't have a tire changer. I probably should have gotten tubes with BENT stems but thought that these straight stems would be OK. The first went in with no issues and I thought that I was home free and attacked the second wheel. When I went to fill the inner tube with air, the stem retracted INTO the wheel and couldn't be accessed. More wrestling with pulling one side of the tire off the rim and deflating the tube somewhat allowed me to get the stem back in the hole. Still not sitting perfectly but at least it is fillable and holding air. I am not sure WHY the stems pull in when you try to fill the tube but I suspect that it has something to do with how it is twisted inside the tire. Foolishly, I thought that it would straighten itself out as it filled. Apparently it didn't. I must have gotten lucky with the first one and got over confident on the second. Proper positioning and perhaps a bent stem version would have prevented all those bad words that were uttered when the stem retracted!!!

Bought these to fix two wheelbarrow tires that were flat. They were easy to install, fit as expected, and they’ve been holding air and holding up nicely so far. Great replacement tubes. Much cheaper than I could find locally.

Arrived when promised. Equal or slightly better quality than original.

Arrived on time and good quality!

Fits in 6" gokart tire hold air in good Nice quality

Good product

Fits well. Working so far. Time will tell if it continues to hold air. Arrived in a timely manner. 4 stars because of the packaging, came in a plastic bag inside a paper amazon bag. Felt the rubber tubes would be better protected in a box less likely for them to get damaged and received punctures. Delivery people are not most careful with parcels.

Fits perfectly. Good quality inner tube. To ensure long service, prepare rim properly by removing any rust or rough surfaces the tube could make contact with. Also check inside of tire itself for similar puncture threats. Lubricate edges of rim before installing tube and the tire itself. Ensure correct alignment of tube to rim & within tire before inflating.
