[AT] tread design

[john hall]

Got to thinking about tire tread design on my last post about sidehill combines. Back in the 70's and maybe 80's I remember seeing advertisements for Ford tractors with diamond style tread tires. Can't remember if they were on the front and back or just the front. I never saw another brand use that style of tread. These were big tractors--100+ hp. What was the reasoning for using that style of tire?
