New BFG 275/70R17 KO2'S

Hello everybody,
I was browsing the web and saw a video on the new BFG tires. Unfortunately they are not available in 255/70R17. The closest size I can get is 275/70R17 there are smaller sizes available but will decrease my overall height. I do not want to add a lift or spacers because I like how my Jeep is stock and would like to know if I can put these tires on with no rubbing or trimming on my stock 14 JKURX. I would like to go with these new tires because it's longer wear life. Here are the specs of both tires per BFG'S website. Thanks,

Stock BFG M/T KM 255/70R17
Section width: 10” on 7” wheel
Overall OD: 32.1”
Revs per mile: 649
Weight: 46.5 lbs. X 4 tires 186 lbs.

BFG A/T T/A KO2 275/70R17
Section width: 11” on 8” wheel
Overall OD: 32.2”
Revs per mile: 646
Weight: 55.4 lbs. X 4 tires 221.6 lbs

X2. It will work and do read that link.

It looks like the battle between Duratracs and KO2s is starting to brew.

Also note the stock KM is a 75 series tire and not a 70 series tire.

They are much smoother and quiter than the mud terrains so far, I'll give a better review after the weekend.

I've had my KO2s just about a week now, love them! They are not loud and a smooth tire. I can feel a bit more compared to stock, but not enough to really notice. My wife says she can't feel any difference. I've ridden in a Jeep with the BFG Mud Terrain and the ride is noting like that. I took the tire store owner out yesterday, well he drove and he was even amazed how smooth they road.

The tires fix in the fenders fine, a bit tight but acceptable. I did add 1.5" wheel spacers to my setup. With the 17" stock 10A rims, 275s and spacers there is maybe 3/8" that is outside the fender, but it's not tread as much as sidewall.

On my 10A going from the mud terrain to this tire is like I'm driving a completely different vehicle. Very smooth at speed. Drove up to about 65 and tracks the road very well. Can't wait to get it off road. I don't have wheel spacers, and don't seem to have any rubbing issues. Wife took it for a ride and I think I lost the Jeep at least for tomorrow.

I only get mine when we both go somewhere.

275/70-17 is so close to stock size it is 0.1" taller and a little bit wider.

Found this thread and though it is a bit old, the topic is not.

Question: I have run the tire size calculator on the 255/75R17 (stock) and the 275/70R17 tire sizes. Would I want to run the slightly larger sized 275s? My Jeep is stock. Thanks.

The Winter Edition comes with 265/70/17 KO2's with special edition wheels (think they are on a few other special editions as well?). Love these compared to the AT's on my Oscar Mike. I thought 265 was odd, but I verified it on the tire.

The 265/70 is a much more common size than the stock size on most Jeeps, it works out to the same height with .5" increase in width.

This. Over 2 years ago, I was in the market for an AT tire. I wanted something wider than the 255, same overall diameter, but not having to deal with any rubbing issues. I went with Firestone Destination ATs 275/70-17. There was not a lot to choose from. I don't recall if the KO2's were even available in this size back then.

Actually, it is .5" smaller in diameter that the 255.
