Review on 🚴 Premium-Quality Butyl Rubber Replacement Tires and Inner Tubes for Kids Bikes (2 Sets) - 12"/14"/16"/18"/20" - Compatible with RoyalBaby, Joystar, Dynacraft and More - BPA/Latex Free by Vic Alexander

They replaced some bad tires on our dog's wheelchair and are of much better quality than these. It's sad that the thorn/goathead seeds flattened the tube but some slime fixed it and they're holding up great. To update. They only lasted from August 9th to September 27th. The cords begin to show through and the tread wears out. We used these tires on a 55-pound dog wheelchair for about 1/4 mile a day (or less) through dirt and pavement. I don't think they are good for that.
