Bought these to change the tires on a 2 year old garden wagon. the original trolley is great, the tires are not so good. These tires are very durable and the sidewalls and tread are quite thick for their size. Leading to the mounting issues mentioned by others, they fitted well, but with some soapy water, some extra long studs, and patience, I was able to mount them to wagon wheels. My trolley wheels break into 2 bolted parts; I was not able to reassemble the wheel halves with the original bolts due to the strength of these tires, but with the help of 2 longer long studs I was able to reassemble the wheels and then bolt on the 2 original bolts. then finally replaced the long threaded bolts with the original bolts. So far they're working great.
