Slime 30010 Inner Tube for Wheelbarrows, Hand Trucks, Compressors, Lawn Mowers, Scooters, Trailers and More, Extra Strong, Includes Self-Sealing Slime Sealant, Heavy Duty Replacement, 4.00/3.5-4"

I used this in the tires of a small work wagon on our place in southern Arizona--where almost every plant has thorns. Despite all of the sharp rocks and sharp thorns (even all of those that penetrate hard-soled shoes), the tires stay inflated for long periods. I've removed multiple thorns that have gone well through the tire and tube, but the tire continues to hold pressure for days--easily long enough for me to finish whatever job I'm doing (most hauling rocks, concrete, wood, etc.)

A good replacement for front tire of 4 in 1 radio flyer trike. It was very very hard to replace but not because of the tube.

I put this on an air compressor, the tire size didn't match exactly but the tube flexed enough that it worked totally fine. Really glad I got this one!

Perfect for my push dolly!

These used to fix flats on my hand truck, much nicer than originals.

works as intended

This fit my gas scooter but I think its a little bit to big but it works good and holds air.
