KM3

Post by Punishher7 » Mon Sep 10, 2018 11:06 pm

Is anyone here running the new BFG KM3 on their power wagon? I’m considering these in 35/12.5R17 on either the stock 2018 wheels or AEV Katla 17x8.5. Any input, photos, and initial impressions would be appreciated.

315/70/R17 - stock PW rims - no rub yet. Great on highway, quieter then DURATRACs.
good ride at 68 psi x 4. can be up to 80. Just put these on.

Are the 315’s roughly 35” or 37” ? The Toyos are what I’m eyeing the most although km3’s and sst’s aren’t ruled completely out either.

Thank you, I totally can’t decide between 35” and 37”. It’s the worst case of indecision I’ve ever had. I keep second guessing myself with the “ what if “ paradox.

I don’t even know why I bothered with 35’s. I love the 37’s more all the time.

For purely off-road the 37 totally makes sense. As my DD I’d like to squeeze every MPG I can out of my PW, while still being decent when we do go off-road. Do you recall the difference between 35s and 37s in day to day MPG?

If you’re a calm driver and go with a light or mid weight 37 you will probably see consistent or even improved mpg over stock.

I work from home, we don't commute. And to be honest, I don't track MPG's anymore. I make enough money. It's never been a concern.

Well until just this past trip to Moab. Milage was so bad, I took a cord of wood with me in the PW along with the Airstream, and filled up more than the last time I towed with the Airstream. Didn't really think the extra weight was that much, but apparently so. Guess it's time for gears.

So what’s a light or mid-weight 37?

Probably a BFG because it'll actually be the size of a 33" Toyo.

Not really sure there is a “light” 37 :lol:

Also, not just weight but less rolling resistance, like a true A/T or even a hybrid, will typically offer a bit better mpg’s as well as life/mileage out of the tire.

While not necessarily light (82 pounds!), I think the 37” Falken ATW3 would be a very nice true AT tire. I have read nothing but raves on that tire. There really isnt many out there to choose from for a true AT.

Im curious, what does your 37” RT’s measure?

New they were less than 1/4" under 37". They have 24k miles on them now which is probably where the 37" BFG would be dry rotted, measure 32", and need to be replaced.

In my mind a light 37 would be a Yokohama MT, Toyo RT

Mid weight would be the Toyo MT 12.5-wide and most other 37’s

Heavy weight would be the Toyo MT 13.5-wide (actually 14.4 if I remember right) and other similar wide tires.

Rolling resistance, tread compound, weight, there’s lots of variables. The biggest variable is the driver.

37x12.50 Cooper STT Pro's weigh 77lbs. That is what I just put on. That's pretty "light" for an 37 MT since pretty much all other major brands are over 80lbs. I say go with a 37. They look perfect on a power wagon. I would have been pissed if I went with 35's. MPG is not really a concern for me because it's bad either way.
