Worst tires I ever saw were Goodyears. Our 285 came with them from the factory. My dad did alot of road driving with them cutting hay for neighbors. I think he said they had maybe 1000-1500 hours on them when he replaced them because the treads were starting to peel from the casing. At the most they would have had 2000 hours. I think they were replaced in about 88 or 87, I don't ever remember the dyna torques being mounted, I'm 22. He had them replaced with PowerMark long bar/short bar bias ply tires. Still on the tractor right now, and it's got 6100 hours on it. They're about 50% still, but until 2 years ago were closer to 60%. Lately it's become more of a road tractor again after I got my 1600 Oliver running so that one runs the blower and the 1855 runs the chopper. The 285 hauls all the loads while chopping, and does almost all of the haying. I'm more sold on the PowerMarks than any other tire right now. They are a little weather checked, but really not too bad for how much it sits outside. One of the GoodYears did end up on a dual rim this summer though after I caught one on the manure spreader making a short turn. (Also do a bunch of road travel while hauling manure.) After the tire was mounted on the rim we didn't need the duals anymore so I haven't used them since. The we bought 1755 behind the barn about 7 years ago, no idea how long the Armstrong's have been mounted. Our 1855 came with Coop radials. They're pretty weather checked and worn down to at most 40%, but it still has a surprizing amount of pull. I've seen a nice pair of Firestone 23 degrees in the bone yard that had about 95% tread last year, but they'd probably still want a fortune for them. My dad bought new tires for my 1600 when I restored it, I forget the brand name but it's something like Agri-Master... I forget. The tire guy said they were the closest to the tread pattern of a Firestone tire. Kinda surprising this guy won't try to push us into buying a really expensive set of tires.... Maybe because he wants to serve us better, maybe because he wants to put a new set on in another couple years.... I dunno but he gave me a bad taste when I drove out there with the dual tire to get fixed this past summer... Donovan from Wisconsin
