AR-PRO (2 PACK) 2.80/2.50-4 Inner Tube for Hand Trucks, Utility Cart, Lawn Mowers, Wheelbarrows, Dollys, Scooters, Replacement 2.80-4 2.50-4 Tire Inner Tube with TR87 Bent Valve Stem

I bought the two pack. The tubes are excellent. Nice and thick. Make sure you notice whether you need the straight or bent stem. It's worth noting that tires this small can be very tricky to repair because of the diameter of the rim. I ended up bending the rim on my dolly, but it still holds air just fine and the hand truck works the same. Bottom line: great replacement tube but difficult to install without knowing the trick to it. On larger tires, the perimeter of the tire should pull to the center of the rim, allowing the tire to slip off of the rim on the opposite edge of the same side (I used two large screwdrivers for leverage.) This didn't work for me, however, and I ended up bending the rim. The only reason I shared that is for awareness to DIYs. The product is an excellent replacement for a tube that can't be repaired, but be ready for a small challenge if you haven't changed the tires on one this small.

It wasn't the right size make sure you measure before purchase

This inner tube more thick than other it durable thanks

Tubes themselves worked well. Very difficult to break the bead, then replace tube with bicycle tire, metal, 'spoons'. Not enough leverage. Ended up using motorcycle tire 'spoons'. Curved valve stems a good feature. NEXT time, I believe that I'll get solid tires.(wheelbarrow).
