Place 2 of these on the lawn cart. It's difficult and requires a lot of energy to put them on the rim of the wagon wheel, but I managed it with just a screwdriver and some elbow grease. Be careful not to cut the tube by putting it on the rim. I'm not a muscle man. You can get them through the rim with a screwdriver and slide them properly. It is not easy. It just takes time and patience. After mounting, these tires are fine.
