 Ya know, you make a very valid point that contradicts what most other guys say, but it makes perfect sense to me. We've got an Oliver 1855 (2wd) that we bought about 4-5 years ago now. It has a pair of Coop 18.4 R38 radials on it, but they are getting down there on tread and they have severe cracking around the lugs. They still pull pretty good, but we plan to replace them next year unless some other unexpected expense comes up. The one really big issue I have with them is the way they ride. They don't lope or anything like that, but they just seem to squirm when on the road, espescially when pulling a heavy wagon of corn silage behind the chopper or when pulling the semi-mounted plow. Our 1755 which had 18.4-34 bias tires had a normal feeling ride. I know that most of the time the tires are awfull close to being overloaded with just the static weight of the tractor, being that it weighs somewhere in the neighborhood of 14,000 lbs with fluid in the rears, a ROPS/canopy, and a pair of fuel tank fenders I just installed. I was tempted to have dad price out a new pair of radials, but the extra expense just doesn't seem worth it for a tractor that only sees about 100-150 hours a year, and the tires would most likely rot off before they wear off. What would be your opinion type of tire? If we can find a new pair of Power Mark L/S's I'd go for them, otherwise we'll probably go with Titan L/S bias tires. Our 285 has a 20 year old pair of PowerMark's on it and they still look pretty good. Our dead 1755 has Armstrong's on it, and our 165 has the coresponding tire w/ Titan on the side. They all seem to perform well for us. Donovan from Wisconsin
