Tires received and mounted. Some youtube to figure out how to do it, and some help from a friend (Thank you Doug!) to use ratchet straps. Once the compressor kicked on and it started to seal, it was pretty easy.
The tires that were supplied with the kit were 14x4-6 tube-type, the wheels are 5" wide-6 tubeless. Now the tires are 15x6-6 tubeless.
Tires are heavier. The 4in wide are 2.2 pounds each, these on the wheel are 6.2 pounds each. Will calculate weight as I go.
I am just happy the tires went on AND sealed.
