Three rib or four?

Do you guys find that three rib or four wear faster on a combination loader/light field work tractor? I'm talking the quality of new tires I would get at the coop tire shop, not an old one that's been on Grandpa's Farmall M for 60 years - I have some tires like that.

All of my fields are within a few miles so there isn't a great deal of blacktop driving but I do haul bales on the loader a mile or two a day on gravel/blacktop feeding.

I guess I should have mentioned that my biggest "beef" is with new tires on an 886. It's the only three rib set of tires other than old letter series on this farm. I have four rib on the only other two wheel drive tractor and they are wearing forever, but it is a 4440 and doesn't have that extreme IH camber setup. The two tires on the 886 blew in haying this year a week apart and the coop didn't have the same brand. One of them has literally worn the outside rib about down and the center rib is following. The other new tire isn't much better - all with less than 250 hours. The old tires were better quality or/and hardened with age as they didn't show much wear at all and just aged out. Both new tires are eight ply. I want to say the "soft" one is a Sampson.

It's a loader tractor so I know they won't last forever and I'm already planning four rib as I think they will last longer. Do they?

FYI - the front end is in great shape, no wear or welds, and the measurements all pan out. It's just a cheap tire. Well, it was still $170, but cheap anyway. I'm already planning for better tires and I'm sure I'm a couple years away.

I think they last longer than tririb.Especially on a loader tractor.I put a half worn set (10:00x16) on my 706 5-6 years ago.They still have a lot of life left in them. The new 7:50x16 tririb I put on the 826 the next year are almost worn out.

I agree with Delta (aka) Steve.
Seems like on three ribs, the center one stands high. Maybe good for cornering in soft dirt. But the four ribs are more even, and I think better for carrying a load.

Have you checked your toein lately, or did you replace a tierod on one side and just screwed it in the same as the old one and not check it afterward? Just trying to help you checkout why one side is worse than the other. We have 4 rib on our loader 4020/148 and they wear good, we move dirt around on pavement at times. chris

If you are looking for long wear get some truck tires.

A three rib with a little wear is much easier on a hay field than a new, or used four rib. If this tractor gets out to help with hay I would use three. A side wall will last longer on a loader/feed tractor carrying heavy bales with four rib. Less flexing on the side wall. Al

I had truck tires on my D-19 with a loader. Age got to them so put new 3 ribs on it. When you turn a corner you plow a farrow. Wished I would of found some newer truck tires like I had before. AC engineers must if took a nap and let the janitor design the wide front ends.

I have 4 rib on my 4020 loader tractor. I like 3 rib for most uses. The 4 rib doesn't seem to damage the hay fields so much.
