1st post by the newbe, need tires

[Jimc3165]

I just bought a 1982 B7100 HST-D and it is in reasonably good condition considering how old it is. It has a fairly new RC60-71B deck with about 250 hours on it. So my main question that has probably been asked many times is what is a good replacement combo for my OEM Turf Tires. I need an Ag tread or something similar, in North Georgia we have this sticky red clay so need something that is self cleaning and will keep digging.

Took this pic this afternoon after the oil change and greasing all the deck fittings. I had a M4900 a few years ago and really liked the tractor. This one is way smaller but it seems to fit my needs well right now.

Jim,

welcome aboard - nice machine - I think you will find it to be a tank , small but rather tough little machine.

as for the tires:



Kubota B7100HST Tires:
Ag front: 6.00-12
Ag rear: 8.00-16

Just to add to what Hokie said. The ag tires he listed do not fit the wheels you have now.

Also.... what is your intended use of the tractor. Very few need "AG" tires in reality

 

[Jimc3165]

The intended use is a small garden, cutting grass, moving dirt and driveway maintenance. But as I said before the sticky red clay we have here makes any job but maybe grass cutting harder. I also have a very hilly lot so chances are jobs will come up that will be up and down hill. I see what Hokie said about the sizes but have been reading lots of post about the importance of keeping the same ratio front to back and was hoping someone had solved the puzzle and could recommend a specific tire combination that would maintain the ratio.

those tires ARE the right combo - however .....as KubotaSam said, and it is a good point, YOU will need new rims.......

thought about chains ? would be a lighter on the pocketbook too.

I don't know if these are OEM but the sizes are fronts are GY trailer service Load Range B 20.5x8x10. The rear are again GY Trailer service 29x12x15 They are cracked up some and since they are tubeless they will start losing air and be a pain to keep up with. I would not of thought Kubota would put trailer service tires on this tractor but that is what I have. Also it is a 4wd HSt-D

It's running the stock OEM sizes for turfs.

Stock sizes on the R1's or AG tires are as 85Hokie noted:

Ag front: 6.00-12
Ag rear: 8.00-16

As has been said, you may not need the R1 AG's. Chains are an option, but you might consider finding some more aggressive treaded tires in the same range. With the small UTV's and very large ATV's out there, you might find something in those tire types that will work on your unit. Industrials (R4's) from a skid steer or larger front loader might work as well on the rims you currently have.

You really have to poke around though, finding tires to fit your need is something of an art form when you walk away from the standard path.
