Rear Tire Sizes??
 

I have 2 model 100's. One has the narrow rims with 6-12 tires. The other has wider rims. One of the wide rims has a 23-10.5-12 tire on it that looks original and has the same tread pattern as my narrow tires. The other tire is a 23-9.5-12 with a different tread pattern and has less dry rot. I'm guessing that was a "close enough" replacement that was installed buy a previous owner when one of the original wide tires failed in some way. The books seem to indicate that 6-12 and 23-10.5-12 are stock sizes.

Now here in Florida, we have a lot of sand. My previous experience tells me that low air pressure and big tires with shallow tread are your friend in that environment. This being the case, I'm wondering how big of a tire I can put on the wide rims without running into trouble. I see that turff tires are available in both 26-12-12 and 26-10.5-12. I'm thinking that these will likely fit but I'd rather learn from the experiences of others before experimenting myself.

Who has played with big tires on the backs of these things before? How did it work out for you? Did you find tires that were even bigger than what I listed?

Thanks,
Jim

Perhaps I should ask a slightly different question.

I see that 26-12-12 and 26-10.5-12 tires are available. Has anyone ever tried either of these sizes on the back of a Cub Cadet? If so, would you please post a picture and describe any difficulties that you ran into?

Thanks,
Jim

The 26" tires were standard on the Super Cubs.
You would likely encounter clearance issues using them on a NF.

Where would the clearance issues likely be?

This is for a model 100 with no mower deck and no fenders.

Also, what was the rim size on the super cubs?

If you don't have fenders you may be okay. Rubbing the sidewall on the gearbox might be an issue; I don't have a narrow frame. Here's a link to typical tire sizes and a photo of 23-10.5/12 tires on my Original.

I found the rim and tire size chart at the bottom of this page

I decided to give a pair of Deestone 26 x 12 x 12 ag tires a try. They actually measure 10.5" wide and 25.5" high when mounted on Cub Cadet rims.

These rims are from a slightly newer CC and each rim has about an inch or so more dish offset compared to my originals. This means that the total width of the tractor is now about 2" more than it would have been if I had used the original rims. Total width is about 39" at the rear wheels now. 3-foot wide gates are no longer an option for me but I can still get into a 45" door, even with the snow plow mounted. The tires still would have fit and cleared the seat with the original rims. I'm planing to keep the original rims for use with stock size turf tires.

I ordered the 4-ply version of these Destones. There is also a 6-ply version that costs about $10 more per tire. The ones I got are plenty stiff in my opinion. They required 2 tire levers to get them mounted. I only needed one to mount 6-12 Carlisle Farm Specialist tires on skinny rims

These new tires grab very well in soft soil

Gear speeds will be faster with the bigger tires.

And speedometer will read incorrect.

Thats ok, the Gubber-Mint tracking that goes on 24-7-365 will note that. :bigeyes:
