34x10.5 KO2

scored a deal ($930) for 4 so I picked them up for some road trips. They are pretty small for 34's and the people that measure them as 33's mounted etc must be using a short tape measure or have a very light rig. With 36psi which is what the shop put in them they are about 33" when measured off the jeep and exactly 32.25" mounted on the jeep. Quiet on the road for sure.

with stock rims they are dangerously close to the rear upper sway bar link ends (I am using JKS adjustable lings and set up properly for my 2.5" RK lift so with stock links might be ok) The fronts don't come close to rubbing on the sway bar.

I have a set Spidertrax spacers coming as I would not venture off pavement with the rear links so close. I am headed to Colorado Ouray area late in the week and should see how they do. When I head to the Rubicon the end of August I will be most definitely putting my Toyo 35's back on but I figured for Black bear pass etc no need for the bigger tires and less wear and tear on the road trip with the KO2's.

@jadmt ... Does yours have a slight audible noise when driving 5-15mph with the windows down? Take not annoying but it's noticeable. The toyos don't do that.

Not annoying or distracting but yes a slight sound like 100s of little suction cups gripping the road that is not present with the AT2's. I figured it is because they are brand new and the rubber is so fresh. They do feel peppier due to the smaller diameter and lighter weight in both acceleration and braking but the crazy thing is mpg has not changed enough to notice at least not for the first tank. Speedo and odo are set spot on with procal and I used 32" as the tire height input compared to 33.75" for my toyos.

I can make the sound but it would not convey well across the screen
I think for road use and winter use they will work good. I figure I got a great deal on them if I don't like them I wont be out too much selling them on CL.

So I borrowed my buddies 255/80-75 KM2 mounted on a stock rubicon rim just as mine are and the 255/80-17 is slightly narrower and actually taller then the 34's.

Interesting. Was that measured under load? The math on the 255/80/17 says it is 33" tall.

math goes out the window when it comes to tires even when comparing the same companies tires.

I was really disappointed to see how small the 34s ended up running, imho BFG missed the mark on that one, I'm sure they will still be a popular tire and will work well with a leveling kit, or on a 4 runner or some pickups, but would have been a winner if it ended up measuring 34 or just under.

But that's the way it goes, should make a dandy winter tire for you I would imagine.

What do your AT2s actually measure on the ground, at a given psi, with the stock/aftermarket rims? Mine were 33" on the Saltas at 32psi. Would the stock 7.5s give a little more height over 8.5s? Thanks.
