Price reduced! 22x1 3/8 wheelchair tires, puncture-proof. Tubeless. Set of 2. Made in China. Thank you for looking! I accidentally bought two sets and have a spare, so I'd be grateful if someone could use them. They're a bit soft, but they fit properly and work fine. I installed them myself. It's just a matter of removing the old ones and putting these on. Tire levers make it easier, I think. Anyone who has changed a bicycle tire can do it. You could also ask a bike shop to do it.
