Tires were tall back then probably a 90 to a 100 on the aspect ratio. A Goodyear AT, was a bit lower I think.
When Yokokama came out with a 4.60 x18.. around 77, I think that was one of the first lower height tires I remember.. and that seemed wide..
My buddy scared the crap outa me, when he installed one, me riding behind him.. he threw it over so hard and far I thought it would never hang on..graunched a lot of header when he did it.
A while back 1080 picked up an old Jardine with the low outer pipe pushed 1/2 way in, I mean ground.. I said, I bet any money that is Ricks old pipe..
