Read the entire description:
I'm mounting new (used) tires on my new (used) truck. The old tires were 9.00 x 20 and the replacement tires are 15.5/80R20. These are supposed to be similar to 395/85/20 tires. They are supposed to be 46.6 inch diameter when new. These tires exceed the max tire size for the rim. The rim is too narrow for the tire. The recommended inner tube size is 14.00 x 20.
These are two piece, split ring rims. They can be very dangerous. They should never be inflated to seat the beads without a safety cage. These tire and rim assemblies weigh about 300 pounds each. They can injure or kill if the ring breaks, the tire explodes, the ring isn't fully seated, the wheel is to rusty, the ring is too rusty or for no apparent reason at all.

As the background noise changed from birds chirping to frogs, crickets, and whatever else, the sun went down. Sorry for the decrease in video quality, but I did improve the video brightness & contrast some to try & make this video view-able.
