The 45 Deg. tires tended to wear funny when run on hard pavement, didn't pull as well under almost all conditions. GoodYear came up with a Zig-Zag lug back in the late 60's called a Super-Torque tire with 45 Deg. lugs, then changed to approx. 30 Deg and called it the Power-Torque. Firestone introduced the 23 Deg. lug in the mid-60's whaich according to Their testing provided the best wear on hard pavement and the best pulling efficiency on just about ALL conditions. Firestone spent the $$$$$ on the equipment "The Machine" and invested the time to be the best rear tractor tire maker, and in My opinion, Still Are. B.F. GoodRich copied Firestone somewhat by coming up with a 30 Deg. angle for their Silvertown Bias tires. They used about a 40 Deg. angle on their Radials they came out with in the mid/late 70's. The BFG radial was about the only thing that would outpull the Firestone because of the wider, longer footprint. Of course GoodYear & Firestone follwed with their own radial rear tires a few years later. And once again, In My opinion, Firestone's back on top again. If You notice the brands used on pulling tractors, granted they all grind the lugs now days, but Firestone will be on about 3/4 of the tractors. I didn't like the looks of them on Farmall's when They first came out, but NOW, I wouldn't have anything But. I really do not like this Long Bar/Short Bar tread design, esp. on Farmalls, The Goodyear OEM Sales Manager told me that tread design was created to fix a problem the Goodyear Power-Torque tire caused on jon dear tractors! The Power-Torque tire caused the cabs to vibrate and eventually shake violently side to side when running fast on hard surfaces.
