Mix matched tire nonsense.

Back tires aren't holding air so it's time to fix what the last owner did.

Front 25x8-12 both. 50% holds air

Rear left. 25x11-12. 30%
Rear right 26x10-12. 20% flat

Gravel 20% trail 50% mud 30% 8 inches deep or less

What would make this OEM as far as difference from front to back? What 2 would you throw on the back?

well, on a 4x4 atv(or 99% of them) you need to have the same tire size(OD) to NOT have any drive line binding or other issue's when in 4x4, NEXT< you need to have two the same side OD tires on rear for 2 wheel drive use, or again you can damage drive line parts, and can get costly fast if so!

SO< that being said, unless your planning to do all 4 tires to a SAME BRAND MODEL AND SIZE<
IMO< you need to replace the back tires with the same model, brand, and OD size(25 inches here) as you have on the front, and the reason being is,
ALL MFG"s of tires do NOT make there tires the same OD,( as an example if you take 5 different brand OEM tires in a size 25x10x12 tires(according to side wall) and measure them, odds are HIGH that you will get 5 different sizes in real world measurements)

SO< this tends to mean, your either going to want to replace all 4 tires with a NEW brand/size tread pattern, or, replace the back two with the same brand/model tire you have on the front!, and that would then mean either a 25x8(or 10 or 11 or 12) x 12 tire, to get the closest thing to ALL 4 tires of the same OD!
if you go larger or smaller tires on front and back, side to side, they will then turn at different revolutions and that is where you get drive line damage!, things need to be the same so turn the same amount!
some folks don't care as much as others and HOPE the tire just spins on the ground , over causing drive line binding, so, your atv, your call, but the above info is honest advice and facts!

Thank you. Sound advice. This has over 5000 miles so any damage is likely already done. I will replace the back 2 soon and do the front with the same a few months later

some of the honda atv's came with(some might still) 11 inch wheels, NO one really knows WHY they stuck with them so long, maybe just to be different?? or got a deal on a huge amount of them and refused to go to a 12 till; they used up there inventory LOL
IMO< most honda atv owners that HAD 11 inch wheels on them from NEW, when the time comes to get new tires, most all go to a 12 inch wheel, as then the options on tires you can run are a LOT larger pool to pick from, very few folks stick with 11 inch wheels

your atv might be on e of the few I mentioned above, that came from the factory with different gearing in front dif and rear dif, and the difference was designed to be run with a 1 inch taller tire in the rear!
so rather than have exact same gear ratio in both diff's they used a taller tire in the rear to make them equal!

so, seems like your atv need a 1 inch taller tire on the rear than from

ALSO< many folks that have atv's geared this way, still run all 4 tires the same size, and the reason being is that they run mostly in mud, and or soft ground that allows the tires to slip and NOT the gears
but this is a personal choice if you do so!

Honda designed there atv';s to be how they designed them, , if you wish to alter such, ?? just know what could MAYBE happen and make your choice that way!

your atv has all 12 inch wheels, odds are due to previous owner added them when they got new tires, very common deal on any atv that came with 11 inch wheels, as not many tire options to pick from on 11 inch wheel sized tires, where as tons of 12 inch wheel sized tire options!
