11.2-38 tires

Wemedeeres · Apr 14, 2018

I'm sure a this question or one similar has been asked but I'll ask it again. I'm looking to put new rear tires on one of my B's. 11.2-38 is the size I need. I'm not going to be actively farming with the tractor just some parades, tractor rides and an occasional plowing event so expensive tires really don't fit the budget. My question is what is everyone else using? There are a couple options in this size, some are listed as tractor or irrigation use. I've heard in passing the lugs are spaced differently on irrigation tires as well as having a waxy or shines look to them. Pictures would be a great help too if anyone cares to post them as well!

I bought some used 38's last year for one of my tractors. The guy at the tire shop said they came off a sprayer.

You don't say what year, model of B you have. If it is the angle or cast frame then that is best size. If it is a pressed steel frome that is size it would have come with but going up one size to a 12.4-38 is better, you will have a better speed for your tractor ride. I had a 46 B with angle frame and had the 10 that the 11.2 replaced and was what should have been on that tractor. I also had a 49 B with the pressed steel frame that orignal came with the 10-11.2 size and it was just too small, replaced with the 12.4 and worked better all around, better ground speed and both tractors were worked on plow and disk. Angle frame you do not want to oversize as that is a smaller engine, pressed frame the over size 12.4 is a lot better choice. I also had a 38 A with the 11x38 tires and a 51 A with the 13.6 tire that was the oversize for that tractor from the 12.4 that would have been orignal. If your tractor is a pressed frame model that should have the 12.4 on you just might find that size to be cheaper than a 11.2 tire and easier to get.

its a 46 with the angle frame and currently has 10-38's on it, that's why I'm going with the 11.2's

They look good. I bought a pair of 11.2-38 tires back in 91. I paid $153 each. Tires sure have went up.

nothing wrong with going one size larger..

I prefer the larger size,,better traction and leaves less ruts..you may pick up a little more road speed too.

I have 13.6x38" on 11" rims on my Late Styled "B" and they look Perfect..

I just checked with my old supplier, irrigation tires would cost you $186.36 each + tube. Titan 11.2x38 high
traction lug $398.00 each + tube. These prices would be put on the tractor at the shop. We have in the past
put a whole bunch of irrigation tires on tractors like yours. I no longer own the shop. Please use the
prices to compare with your local tire shop.

T he 46 has a high speed transmission and if you oversize you do not have the power to travel in high on the tractor drive if you have much for hills. 5th in your tractor is close to 6th in the pressed frame models. 2 sizes over on a pressed frame model is just too big to work good all the way around. With the 4.5" low compression engine you have and the high speed gears you do not want to oversize. For me plowing with the 46 it was low gear with 2-12" plows, the 49 with the 4 11/16" gas engine plowing with same plow 3rd gear. that was with the 12.4 tires, if would have tried the 13.6 tire would have been down to second gear.

My tire guy doesn't carry the irrigation ones but has a similar price as you'd stated. I've never seen those in person so I'm not sure what they look like, are they the same as a normal tractor lug with the same look? My tire place said he'd order them in but if I didn't like the look of them I'd have to pay to send them back, I'd like to avoid that if possible.

Leroy · Apr 15, 2018

He should be able to get pictures of them for you. I would question wearability on them tho. On the irigation wheels in their lifetime they probably would not get 5 mile of travel or less than a sixth of the miles on one tractor drive. Rubber not made to ware.

As previously stated the 11.2X38 is going to leave the B looking weird by squatting low in the rear with the front end higher. Plus there is the other issue of always driving uphill which uses more power and fuel.
The largest factory 38" tire on a B was the 11-38 which is now the 12.4X38. A 13.6X38 on an 11" wide rim is not a particularly tacky thing to do and they work well although 12" rims are ideal.
Just out of curiosity, what width of rims is on hand ?
11.2X38 are 57" high and 172" circumference.
12.4X38 are 59" high and 178" circumference. 1" height gain.
13.6X38 are 61.5" high and 184" circumference. 2-1/4" height gain.

I purchased a set of 11.2-38 irrigation tires for my Farmall H and am very happy with them. They are made by BKT and do say irrigation on them.
The rubber looks the same as any other ag tire I have,no unusual gloss or sheen, and the tread pattern is similar to a regular R-1 ag tire.
The price was the main reason I bought them, considerably less than a regular R-1 tire, My tractors are all for play so I cant say how they would hold up in hard
use, the shop i purchased them from said he has sold many of them,and that they would take any thing I could throw at them.
The tires on the Moline are Armstrong 12.4-38 R-1 for comparison...Tom

I will say they NEVER LOOKED LIKE THAT TO ME. The 46 B I had with the orignal factory 10x38 Firestone closed center NEVER looked squating down in rear. And neither did the 49 B with 12.4 or the 51 A with 13.6 tires. And I have never seen and=y at any other place that looked low in back with those size tires on.

Wemedeeres · Apr 15, 2018

Thanks for the pics Tom, that's what I was looking for and I think they'll look just fine!

I'm not one bit concerned by it squatting in the rear, this tractor has the same tire specs as one owned by a good friend and his has no squat to it at all. I remember now why I don't spend as much time on this forum as I used to as well as post a question.....

What could you possibly be insulted about ?
