Hello All. Looking at replacing my stock Maxxis tires on my 14 Grizzly 700. Looking at the Maxxis Bighorn 2.0 Radial which closely fits my riding terrain. My tire guy has suggested that I go up a size on the Bighorns to 26X9X12 and 26X11X12 from stock size 25X8X12 and 25X10X12. The ONLY concern I have is how much of an increase in diameter the up sized tires will add to the total length of the atv. When loaded into the back of my GMC Sierra with 6 1/2' box, the tailgate closes with 1/4" to spare. I DON'T want to lose that ability to shut the tailgate. Was hoping someone on the forum may have done this up size and whether they could still shut the tailgate without forcing it on a similar truck with a 6 1/2' box? TIA for any and all responses!

Do the tires hit the front of the bed and tailgate now and are the limiting length items?
I don't think it will matter, the tires are not the things that are the longest, the bumpers/racks are what are at the ends.
If the tires are hitting the bed, the new tires are only 1" larger diameter so they will only add 1/2" to the front length and 1/2" to the rear length so 1" total longer length measured at the tires.
At 4-6psi they should be able to compress fairly easy if they do touch the bed.

The unfortunate issue might be that manufacturer listed sizes have been proven to be misleading. Seems with the tight tolerance the OP is stating, they may need actual 3rd party measurements of the specific tire being asked about. The Bighorn 2.0 does have shorter tread depth than the Bighorn original but the Bighorn original tire in size 26x9x12 actually measures taller than 26" diameter. So I do see the reason for the OP's question.
However, you also have a valid question about how the Grizzly sits in the truck bed. My Grizzly 700's front bumper will come in contact with the truck bed or back window, not the tires. But I've also never tried it as I have the longer bed and it has been multiple years since I've "in" bed loaded my Grizzly on my truck.
@salter Another option, albeit more expensive, would be to look into something like a Diamondback ATV tonneau cover or similar. That way you can load your ATV where it sits on top of the truck bed either forward facing or side loading. Then your currently stated issue goes away with an added, paying for the cover issue. The Diamondback ATV tonneau covers are really well made and I love having mine but they are not cheap and do not grow on trees for freebie picking. I found mine used and paid $1200 for it, worth every penny to me. New, they can be 3x that price but best to look on their website to confirm pricing.
Thank you both for replying. To clarify a little on your replies. The front of my grizzly contacts the front of the truck bed with my winch rubber stop. The rear of my grizzly would contact the tailgate with the rear tires. If I get it in the box perfectly square, I am left with 1/4" to 3/8" clearance between the rear tires and tailgate with the stock tires. A slight height increase shouldn't affect any contact points. I wouldn't mind having to snug the tailgate a little to close it, but don't really want to have to force it to close.

u would greatly benifit from going up a size if u need the clearance.25 are small.it should still fit in the back of the truck as long as u dont got spacers on the tires.

I know you’re trying to leave your tailgate up but jic you no longer can, there are still good options to secure your griz. I’m running the Kolpin lock-it-rite and it works very well without using any ratchet straps, also frees up about a foot of space in front of the quad where I store gas cans and other miscellaneous items.

until u kit a good bump and your hitch breaks and there goes the bike.i wouldnt trust that.
I know someone who has been using the original version made by Guard Dog and he has used it for over 6 years without any issues. That includes having put thousands of travel miles on while using it. They are actually pretty stout and hold up well and seriously doubt a hitch receiver will fail using it.

It’s not going anywhere, taken it through plenty of “good” bumps and bad ruts. I trust it more than ratchet straps, definitely more stout than it might appear. I use a hitch stabilizer to eliminate some of the play. Wouldn’t take it off any sweet jumps though.

Just a suggestion, but make sure to check your local laws for load securement. Most places require 4 point securement, meaning 4 straps, not just 2.
I inquired here in Ontario, Quebec, and New Brunswick, 3 provinces I travel through hauling my bike on vacation. I wanted to strap my 2 front tires down like I normally do and use a solid hitch mount for the rest since it's hard to strap my tires near the front of trailer once bike is in there. Solid mount is great but only counts as one point securement in the laws eyes.
Also found out that the winch doesn't count as a securement device. I figured as well from loading upflatbed & float trucks at work
Thanks again everyone for the great replies. I definitely am replacing my stock tires with the Maxxis Bighorns 2.0. My tire guy has agreed to work with me to measure up the up sized bighorns and compare to my stock tire measurement. He told me he has a set of the up sized Bighorns on his 13 Grizzly 700, so that should tell me if the up size will work. My goal is still to keep the grizzly in the truck with the tailgate up. There seems to be overwhelming support among Grizzly 700 owners in this forum to go with the up sized Bighorns. I should know within a week or two if it will fit and I will post the result. Thanks Again everyone for the suggestions.

Your stock tires are not a true 25"s, they are 23.5"'s true.
The new tires you're considering are more than 1/2' TALLER so......
If you're going to use a small truck, don't expect toooo much of it at work
I've known a couple members that made ramped steps for the bed of the truck against the bulk-head, to pull the A.T.V. tires up on. I don't have a picture and don't remember the height required.

I use this little homemade setup for my Tundra 6.5 ft bed. I had front and rear bumpers on my old Grizz and it would fit. The little ramps are 4x4 screwed together. That Titan setup would work well too.
