running the 325/80R16 on my TJ. This size is almost the identical height as the 37x12.50R17
We are running the 37X12.50R17L Falken Wildpeak ATs and they measure about 36.5.
mounted on 16x8 wheels with 18psi in them. 325/80R16 measured 35.625"


18 psi vs 28 psi makes the inch difference? (guessing on wolettes psi...) Or the 35.6 is an actual measurement, and the 36.5 is based on the mfg's spec'd height? Or thicker sidewalls on one? Or something to do with a 16 inch rim vs a 17?

A little more info...we are running a 17 x 9.5 ATX Beadlock wheel at 28 psi. We measured the spare shoulder to shoulder and it is about 36.5.

Gotcha, vehicle weight caused most of the discrepancy.

Well I've had them on for a couple months and I love them!

Amazing in rain, not even a hint of hydro planing in standing water on the highway, a lot firmer then the stock crapyears, so the Jeep feels more planted. Feel a bit more in the steering wheel, but not enough to be annoying.

GREAT in the snow, was out last night in our "blizzard", I had the roads to my self so I wasn't exactly taking it easy on the skinny pedal, and had no problem going anywhere I wanted.

They're "ok" on ice, had no problems getting going, but slid a little sideways coasting up to a light on an off camber road, tossed it in neutral to take away the engine breaking and it straighten right out. But I don't think too many non-winter tires would have done better.

I'll definitely be replacing them with more of the same, probably bigger if I keep the KJ and lift it. Maybe I'll let discount sip the next set.

the name stamped on the side of the tire from what I've read.

The rocky mountains are made specifically for discount tire.

Discount told me that the wild peak is like 20 dollars more than the rocky mountains.

@wayolifette- What size of lift are you running with those wildpeaks? I'm thinking about getting a set if they will fit with my RE 3.5" lift.
