23x10.50 vs 26x12
 

Is the added fluid capacity of the 26x12 tires worth the loss in surface pressure and overall gear reduction over the 23x10.50 tires?

I would guess that all depends on what tractor and what your trying to do with it. :bigthink:

I like my bigger tires BETTER!!

These stick like glue, but, they are radials!! :bigeyes:

NO fluid needed!! :bigthink:

129, ultimately It will be plowing as well as other heavy ground work.

I think I'd add weights (and fluid) to the 23 inch tires rather than go to the 26 inch tires, especially for ground engaging work. Not only will the 26 inch tires be a tight fit, you can't put chains on them like you can on the 23s (due to clearance issues) for pushing snow.

As you've stated, you will also lose mechanical advantage with the larger circumference tire.

Any thoughts on the 24x12x12 ags on the market by chance?

I feel quite certain that IH did (at least) a little research before deciding what tire size would be most advantages' for torque, ground speed and traction in all around use before production ever started.

Although, I do have 2 pair of used 4 wheeler tires that I use as temporaries when I get a "new" tractor that has rear tires that won't hold air, they look pretty beefy, but I don't know how practical they are.

Selections where also smaller back then. 23x10.50 predates the cub cadet.
