Gentlemen,

I'm going to be needing tires for a tractor that I just bought. It's a Large Frame Bolens and takes 26-12-12 tires.

I have a pair of 26-12-12 CST Ancla tires on my 1886 and am planning on putting Anclas on this tractor as well.

I have found a site with some VERY good pricing on Ancla tires. I can get the 26-12-12 for $96.99 ea.

However they also have the 12-11-12 tires at $72.99 ea. We are talking a savings of close to $50.00 for a pair.

The load rating for the 11-12 tires is 480# while the 12-12s are rated at 520#

I'm leaning heavily to going with the 11-12s. I don't see me having all that much weight on the tractor, and I doubt that I would lose that much traction with a 1" width difference.

Also the $$ savings can be put toward a pair of front tires which it needs as well.

What say you?

Will you be using any heavy attachments on the tractor? If you're not using an FEL or a big tiller it probably won't make any difference. See what other responses you get over the next week or so. Then you can decide. Please let us know the results. So far the tires on my large frames are still ok after 45 years. Amazing isn't it? Good Luck

Seems like the 11" tires would be fine, and 1" less width would give you somewhat better traction, I would guess. More pressure per square inch on the ground. Always good to save a little cash!

Is there a difference in the height of the tires? I'm thinking that the 12-11-12 tires may be 24" tall instead of 26. The 12-16.5's on my 2320 are 33" high or twice the rim size. I don't know if that would apply to the tires you are considering but if they are shorter it would affect the look of the tractor unless you downsized the fronts as well.

Old Buzzard,
Did you mean 26 X 11-12 tires? If so I don't see a problem running them instead of the 26 X 12-12 tires since the second number is tire width in most cases.

Save some moolah, me thinks. What you're saving there will pay for one front tire. My guess is you will hardly be able to notice the width difference. I would venture another guess is that the 11-12 tire will end up being a 1/2" shorter when mounted on the rim than the 26x12x12 tire. Not sure if that would cause an issue for ya or not.

Yeah, I made a typo or two. It should be 26-12-12 tires vs 26-11-12 tires

I'm planning on putting 18-8.5-8 V61s on the front.

Okay then, it will pay for most of one front tire. Are you planning on the 4 ply or the 6 ply with that monster 3 cylinder?

The 11-12 and 12-12 tires are both 6-ply.
