Oh goodness, you have the Ag tire setup. Not the turf tires. The B7100 was sold in two tire configurations, with unique wheel rims for each configuration.

6-12 is the tire size you need for your fronts and you can get them from Amazon.
Yes, I found the Ag tires on Amazon & bought them. Just mounted 1st one. Says on the tire 40 psi max. What are people running for psi with ag tires. You say model came with 2 options for tires, & the book just says 18 psi for back & 14 psi for front. Tractor gets very little use really. To small for me to be comfortable on, really just use to till garden & move heavy things from time to time.

Thanks for everyone's help here, it is very much appreciated.

Are there others who have bought those predators for there b7100? I have turf tires from the factory still on my tractor that the fronts are starting to constantly lose air from dry rot.

But like others mine are 20.5x8-10 with my rears being 29x12.5-15

I'm just paranoid about getting the wrong tire size for a 4wd tractor. I really wish we had more options but it seems we are highly limited. But at under 70 dollars those amazon predators look nice. I just don't want to introduce new issues. I use this tractor all the time.

My B7100HST-D has the 20" Predators and they're just fine. I have not experienced any ill effects running in 4WD, but I run exclusively on turf. They have a nice bit of bite but I have not had any problems with tearing turf unless I absolutely bog into a pile while using the loader.

Any reason to not consider the Kenda K513’s in 20.5 x 8-10?
I run a pair on the front if my B7100 hst with turf rears.

FYI, Wal-mart lists them for about $66.

Another bump for this thread!
I am about to pull the trigger on some new fronts and wanted to ask those that have put the Predators on their thoughts after 1+ years with the tire, and how they might compare with the Carlisles.

Well I've been using the Predator for almost 2 years now, and have no complaints. No cracking of the sidewalls to date, no problems with traction in ice and snow. No damage to the lawn in summer. Obviously these don't have the mud traction of R1 tires, but neither did the Carlisle AT2. Performance seems about equal. Longevity is yet to be determined (the AT2s lasted 8 years). Price is way better, although I can't say how the tariff situation down there will affect things. I'm pretty sure the Predator was made in China whereas I believe Carlisle still makes some tires in the US.

Torch I just ordered a set of those tires you have on the front of your tractor in the Carlisle all Trail just wondering how you are feeling about them now. They look like they are good tires for the situation have you had any problems with them I ordered mine through jet.com online

Hi, wondering if you could help me out I’m restoring an small early Kabota tractor, I am looking for the Goodyear 20.5×8–10 vintage tires that they ran originally on the front wondering if you have an old set laying around or nowhere where I could find a pair I would greatly appreciate it. I’m willing to pay good money for them. Any leads would be greatly appreciated. Thanks, Mario.

As you've clearly discovered, you are hunting for a unicorn. You might try Mountainman (listed on the Vendor's page) who has a small-tractor salvage yard.

Not made by Goodyear, but have a very similar tread pattern and size: https://www.amazon.com/HORSESHOE-20x8-00-10-Pattern-Ridding-Tubeless/dp/B0BZNCGLBW

Help me understand the reluctance to running the Kenda 513 turf tires when clearly finding a set of original good or new old stock Goodyear's is going to be, pretty much as Torch said, a unicorn.

They are a true turf tire tread pattern much like the original Goodyear turf tire in the proper size,
20.5 x 8.00-10. 4PR. Same exact size as my owners manual calls for when equipped with Goodyear Turf tires.

The casual observer would not notice these are not the proper front tire , especially compared to the trailer tires and other options folks have used.

I have used these tires on my B7100 since 2021 with good results.

Thanks Ken for your response, my reluctance to other tires of that size is because I’m looking for that street type vintage look that the Goodyear tire has (non turf) I know Goodyear doesn’t make them anymore but maybe NOS if I could locate them, thanks for all your help, I appreciate it!!!

Ok, I am not sure I know what that look is? Can you post a picture of the tire style you are looking for? Did Kubota ever offer the "non turf" tire as an option on the B7100? What rear tires are you running now?

Other than not having the Goodyear branding, are these not the style, tread and size your looking for? The tread style looks to be just about identical to the pictures of the tire your looking for.

As a side note, to be clear, to the best of my knowledge this style tire was never offered as an original Kubota option. Still wondering what your tractor is running on the rears.

That's not the original style tire. That's a trailer tire. Many have used those as a replacement when the original turfs were discontinued.

And actually, now that I think on it, I believe the originals might have been made by Firestone.

H the rears had Carlisle turf tires not originally on it I’m replacing them too, I’m not concerned about what the tractor had, those are the tires IM looking for, I’ll keep searching and hopefully they’ll show up, thanks for all your reply’s and help!!!!

You’re probably right, they probably ran Firestones, but I’m looking for the certain tire by Goodyear, hopefully I’ll find a pair. Thanks for all your response and help. I appreciate it!!

Ok, good luck. You now at least know you can expand/refine your search by looking for Goodyear trailer tires in that size.
