Improvedhand 4.10/3.50-4" Tire Inner Tubes with TR13 Bent Valve Stem, Heavy Duty Premium Inner Tube Replacement for 4" Carts, Hand Truck Dollies, Wheelbarrows, Lawn Mowers, Trailers - Pack of 2

It was a great fit easy to install. It is holding up to the loads I put in the wheelbarrow.

Easy to install and durable

It was a tad bigger than the original but I shoved it in the tire inflated it & I have working wheelbarrow.

I had this hand truck/dolly in my garage for over a decade. Went to use it recently. Was able to fill one tire with air and other was flat. If you can do it yourself and willing to put in a little elbow grease. And the tire still looks great and don't need to buy a new pair. I would find the right size tube needed and do it myself as I did on the right wheel. The tire at first was tricky to get the ring off and the wheel came right off. Then getting the inner tube out and realized where the holes were not worth patching. This is a great product. Just placed the tube in today. Added air and the pressure is great. This hand truck can hold up to 500lbs. Am a happy camper. On to other projects. Thank you

Had to have these installed by a shop. Too much trouble for me getting the tires off and tubes installed. Ten or fifteen dollars each and once installed, no more flats from weathered and cracked tires doing a slow leak down. Couldn't be happier. Saved a lot by not having to buy new tires although a puncture will need a patch on the tube not a plug in the tubeless tire. That would be a trip to the shop for me but maybe not a big deal for others.

easy to use and works

the review that said use locking pliers to hold the valve stem - I should have listened up. The first tube I lost the valve stem inside the tire I spent a lot of time trying to get it back. the 2nd tube went on quicker (used pliers) and was back on the tractor in 1/3of the time. Holds air and does what it should. price was reasonable compared to getting new tires.

Feel nice and thick. Fit perfectly.
