QR Code Link to This Post two thirteen inch 5 on 4-1/2" B78-13ST rims and tires. These are off of a Kendon dual motorcycle trailer. Although the tires have less than 6000 miles on them, they are ten years old and have some cracks on the sidewalls. There is a lot of tread left. One of the rims has a small amount of rust that is oxidized and difficult to notice. They hold air with no problem. TEXT ONLY to show contact info Let's block ads! (Why?)
