Hello. I’m new to the forum. I was just on here to try and get some answers. I have been wondering what kind of wheels these are. They are off of a 1987 trx250x. The bolt pattern is 4/144. The tires are riken road arrow 144/80r 10. The tires are cut for better traction on the track. Old school Mx tires. Anyways, if anyone got any answers cool if not then I guess we’ll never know.
