These are all 8” trailer rims.
All of them 4.80-8 tires.
All of them are leakers - buy for the rims or tube them.
Pic 2 - Top and right tires are Goodyears. The left one is a Carlisle with some cracking but like new tread with nibs yet.
All have great tread yet - but don't hold air for long periods of time.
