Tires Have a tire problem with B2150

[Xplorer]

Hello all. I have a B2150 that has slightly oversized tires that were installed by the previous owner. Current size is 24x8.50-12" front and 13.6x16 rears. All are turf tires and use chains on the front for snow removal. The fronts hjave beed plugged several times and are very dry rotted. The 1 front needs air every time I use the tractor and the other front is almost as bad. Original tire sizes were 6.50x10 front and 12.4x16 rear. Rears are in good shape, but need front tires. Have checked around and found that they discontinued 24x8.5-12's. I'm told that I need to buy new rears and front wheels and tires for many $$$. Anybody know any cheaper solutions? TIA

There are nineteen options for replacement front tires on eBay, most less than $100 per tire:

Tubes as a stop gap?

When I click on the link, it shows ATV tires and when I remove the comma to show 24x8.5 12 it only shows chains for a ATV. When I asked a dealership that sold the tractor (years ago) new about swapping the front tires to R4's, they said to do that with the 4x4 tractor I would have to replace all the wheels and tires to make sure that diameters worked with the 4x4. The rears don't link and are loaded so didn't do that at the time. They had take offs that would work, but $1200 was out of my budget. I wanted to change to R4's due to the turf tires slipping in damp conditions when trying to turn.

I was told that with the plugs in the tires(original owner was building a new house and plugged the fronts more than a couple of times) they said the plugs would ruin the tubes. correct?

I am not a tire expert. All or most of your size front tires on eBay should fit your current rims. A 1/2" variation in width is not going to make much difference. Tire inflation can make 1/2" difference.

Rubber on the ground is generic. Nothing special about ATV tires compared to tractor tires if the tire size is appropriate for your rims.

The numbers 24-8.5-12 represent the dimensions of the tire. The first number is the height, the second number is the width & the third number is the diameter of rim that it will fit on.

Likely more alternatives on Amazon.

More 24-8.5 12 venders via Google search. ~~ Home Depot is one vender.

These offerings are around $65 per tire.

From the research I've done and what I was told by dealers (tire and tractor) that if the outside diameter is different by even 1/2 inch, it will cause problems. I know for a fact that when the tire gets low in air (1/2"?) that it gets stuck in 4x4 and will not come out till the load is taken off by raising/unloading the front tires by lifting off the ground with the bucket. Just low air pressure causes excessive binding of the 4x4 so a 9.5 or a different type tread would be even worse, no?

edit for poor spelling lol

Consider that the tires now on your rims may not actually be the proper size for the rims.
Who knows what the prior owner did? Consider taking one of your existing front wheel/tires to a competent tire shop and having it measured.

Your current tires are likely much less supple than new tires, which could make the difference.

The tire size is stamped on the wheel and matches the size on the sidewall so I'm sure the wheel and tire match.

Good.

The venders in the LINK I sent you in Post #6 have exact size 24x8.5 12 replacement tires.

Thanks to all for your help.

Actually clicked on each link...none were 24x8.50-12

Yes, this need not be a real expensive thing. There is no point I can imagine that would cause you to need to replace wheels !! I have two B2150s. One has the same size turf tries as you describe (those to my knowledge are not oversized at all.) My other one has AG tires on it which I have swapped from one of the B2150s to the other (rims and all.) Those front tires can be a nuisance for less than obvious reasons. They are two-piece wheels and without tubes they can leak between rim halves which mine were doing. Second, do not worry about plugs causing holes in your tubes. As someone else said, just take both front tires and wheels to any full service tire shop and tell them you want tubes put in. I cannot recall if the wheel halves stay bolted together but probably do. Have the tire shop replace the plugs with " inside the tire" patches if need be. If the tires are all that rotten, replace them. Mine are over 35 years old and work fine. Somebody somewhere makes every size tire that was ever mounted on a Kubota.

Good luck. Do not despair!

I thank you for all the information. I never thought of that till I had already made a purchase of new tires on a recommendation from another source. I was told that the 24x9.50-12" had the same rolling diameter but were 1" wider. Wish I would have seen this last post before the purchase, since I think the leaks were from the wheel halves and not the plugs. Could have saved myself $150 minus the tube costs. The tractor has only been used for snow removal and couldn't tell if anything was binding due to size issues. I do know that the chains I was using on the old tires won't work due to clearance issues. When he weather turns nicer, I can then tell if there will be an issue with binding due to unequal diameter issues. Once again, thanks for the inputs.

I don't know if it is worth it in your case or not but some people add spacers to the rear wheels in order to gain room for chains. For my 2 cents worth I would try chains in front only and see of that is adequate. I also found that AG tread tires are SO MUCH better plowing snow and blowing snow than the turf tires. Having 2 B2150's I use the one that has AG tires at my snowy location and the other one with turf tires where I do no snow work.

About spacers: I found them game changers -- REALLY major changes when I put 6" spacers on the back of one of my B2150's. Installation was not hard. The tractor is now stable on steep ground where before it was just tipsy and unsafe. Spacers did create tire interference with my belly mower but I had a mod done to get around that. Somehow the Japanese have never quite absorbed the fact that many users operate on steep ground and need more rear wheel spacing.
