Help with tire size (Maxxis Bighorn) & any needed mods for 2020 Kodiak 700 eps

I just bought 2020 Kodiak 700 eps. I want to upgrade the tires on it to 26" to be specific Maxxis Bighorn 26" tires. I am kind of stuck on Maxxis Bighorn. Unfortunately Maxxis Bighorn OG 26 only come in 26/12/12 size for the rear. I was told the OE rims are 12x7 and 26/12/12 is too wife to fit on that rim. Is that the case? Is anyone running any kind of 26/12/12 tire on OE rims? Can it be done? If not I guess my second choice is to go with Bighorn 2.0 that comes in 26/11/12. I am going to run 26/9/12 in the front.

Little about my use: Mostly trail riding on trails with more sticks than anything. 90% use on personal property in Texas.

I run 28-12-12 wildthangs on my rear stock rims with no problems.but the bighorns are more of a square tire so it may round off the tread pinching them on a thinner rim.
I checked after I posted. The front rim is 12X6 and the rear rim is 12X7.5.
What size are your rims? I am assuming same as on my kodiak. What tire do you run?
Yes. Many, many before you have run Big Horn 26x12x12 on OEM rear wheels. Myself included, you'll be fine.

Thank you I was looking for that experience. What air pressure did you run on Bighorns 4psi or 5psi on ATV. Also how do Bighorn 2.0 compare to the Bighorn OG for our light machines? Knowing what you know would you go with Bighorns 26/12/12 or Bighorn 2.0 size 26/11/12?
Another thing that comes to mind could I run Bighorn OG in the front and Bighorn 2.0 in the back?
The Big Horn 2.0 has less tread depth and will not last as long. I personally wouldn't mix the two as I'd want a full set. I really liked my combo of 26x9x12 (F) and 26x12x12 (R) and the traction is very, very good. I end up riding at higher psi than what Yamaha suggests, around 6psi F and 6.75 psi R. We have extremely rocky conditions where the rocks can be sharp and I've sidewall sliced two front Big Horns, only one being save-able. Both of those tire's sidewalls were sliced with low psi. My conditions may be different than yours, so adjust appropriately for your terrain and skill.

Now that I have a new-to-me 14 Grizzly, I'm moving to a slightly different setup when I go to buy tires... yeah, I know seems foolish if I liked the Big Horns I had. My 14 came with 14" wheels wrapped in ITP Terracross tires. As of last weekend, I've learned I don't care, one bit, for the 26x8x14 front Terracross tires. One is they are too narrow (that may be the biggest issue) and secondly, those front tires tracked like crap, especially when I was climbing and came to snow drifts. The damn tires would not steer in the direction I intended to go. It became frustrating to a point I went and spent some money a couple days ago.

I ended up buying two matching 14x6 wheels to run a square setup for when I go and buy new rubber. However, I'm most likely going with 27x9x14 tires on all four corners using the same wheel, 14x6, on all four corners. I'm stepping up 1" in tire diameter to get back a bit more volume on the 14" wheels. That results in a fair selection of tires, but not all of them come in that size. I'm also considering a 10" width but that narrows the selection more. I'm looking for a tire tread best for rock crawling, hard pack, decent on snow. I don't care about mud traction, not what I ride or look for.

That is good stuff man. Thank you, gave me enough confidence I have gone ahead and ordered 26" Bighorns OG should have them installed on Thursday. Very excited. Another quick question is would i need to mess with the clutch weights at all going from the stockers to 26" Bighorns?

Now about Square setup: My 2020 Grizzly XT-R came with the square setup that I like. But it came with Maxxis Zilla tires and since I hardly do any mud and mostly trail85% and pavement15% riding I think that tire is too much. I would like to honestly go to Bighorns for XT-R as well. The rims on it is 14x8 and current tire size is 27/10/14. Maxxis makes Bighorns in 28/10/14 so I am thinking I will upgrade to that.
My recommendation is to take the Kodiak and run it around for a bit, then change the tires and do the same run. See what it feels like after adding the Big Horns. Chances are you will fee the difference but is it something you feel you'll want to CVY mod is entirely up to you. Some add heavier tires and are completely fine still.

Are you absolutely sure the wheels on your Grizzly XT-R are 14x8 and can you verify? I ask as the standard Yamaha wheels used on utility ATVs are 12x6 (F) and 12x7.5 (R). I had never heard of a 8" wide wheel for a Yamaha ATV but being as the square setup is new to the Grizzly, I have to ask about wheel width. Thanks.

I heard that 14x8 somewhere to...
I wouldn't want that either!

Considering you ll be sticking with 14" wheels all around, 27x10s would probably give you better overall ride quality when compared to 27x9s, in my opinion.

Yes the XTR SE Grizzly does have a square setup with 14" wheels. Seen a couple on the show room floor and you can verify it on Yamaha's website when you bring up that model Grizzly.

We are aware of that. Yamaha has been using the 14" wheels with 10" wide Zillas all around for 2 years now.

The question is if these 14" wheels are actually 8" or 7" wide....

Oops sorry. Read too fast

It is 14 x 8" wide. I checked on my XT-R, unfortunately it is hard to take a pic.

It is super hot here in Dallas today. To get a pic I will have to take of the wheel and tire. Will do that in evening.

27x10x14 doesn't offer a very good selection of rubber. I suppose I could be looking for 28x10x14, just didn't think of going that big. <that's what she said>
I'm really surprised to see that. Thank you for the confirmation!
