Is it time to start the KM3 conversation??

I wouldn't say that unless you have inside info on the actual rubber formulation of both tires.

I have lots of tires that you couldn't tell apart visually (slicks of the same dimensions), but they perform vastly different from one another. Granted, off-road tires owe much of their performance characteristics to tread design, I would wager that rubber composition is at least as much a factor.

For sure. They probably made them softer for better traction.
 
Ordered 285/70/17 KM3s last night for my 4Runner, and ordered a set of KO2s at the same time for the wife's Subaru. That price total stung a bit.
 
Got em.

No snowflake, just M+S. I can tell you they did excellent in downpouring rain today with standing water. We don't get much snow here, so that wasn't a big concern for me.
 
No mountain snowflake is a dealbreaker here on the southern edge of the Sierras. Without the snowflake, cops will ticket you if you head up to the mountains without chains and ignore the "chains required" signs. But they allow snowflake rated tired

Saves about 50 lbs of cargo and a little space if you're not going somewhere super-hairy.
 
Tire Rack has 295's for $288, free shipping and $100 prepaid Mastercard. Probable have to pay tax though.
Don't see the 295's at DTD

1. Snowflake symbol isn't required if you have 4x4 and M+S tires in general during chain enforcement

2. You still need to carry chains somewhere in your vehicle during chain enforcement.


Here is my reference from the california department of transportation:

KM3 ordered

Nitto Terra Grappler 265/70 17 side wall was sliced by a rock on the trail (sections of the trail are rated as 7 so it wasn't an easy one)

The Nittos came standard with the TRD Pro and I had them since March 17, they have 10K on them including quite a bit of trails hours. I was happy with the overall off road/on road performance of the Nittos but was surprised as to how easily the sidewall ruptured.

The Nitto Terra Grappler model I have on my car has been discontinued and only G2 is available. Not interested in mixing two models even though they are very similar.

Ordered KM3, should be installed by Friday (will keep one of the Nittos as a spare instead of the OEM spare); if anyone cares for a follow up report just let me know

Beefy Tread

KuM3s tread is more beefy than my last set of rubber (KO2s).

$4.99 Ribeye from Stater Brothers/KuM3 review

$3.99 a pound NY's from Vons??
That's a picture from 4th of July BBQ $4.99 BONE-IN Ribeye from Stater Brothers.

I tested out he KuM3s yesterday at White Mountain: Suicide Hill in Big Bear. I wasn't too impressed with the traction on loose dirt/sand while going up the hill. It could have been the line I took or maybe I was over confident but I was surprised at how hard it was for me to get up compared to the others in my group that went after me.

I'd say, compared to the 285/70/17 KO2s vs the 315/70/17 KuM3s they are about 10-15% more noisy when 20-60 MPH accelerating but at cruising speed 70-80MPH they aren't that bad. The larger size tire and the absence of rear and front splash guards might attribute to the noise.

I did notice that when I aired down to 20PSI, I know I should have went lower they did grip better on the dirt roads and felt more "planted". I did notice that the rubber compound of the KuM3s was softer vs. the K02s. Honestly I think I'm a AT tire person for the reduced noise and comfort but I am willing to stick it out and run these KuM3s to the ground.
 
Long weekend in southern Utah hitting a couple trails around Kanab and St George. I have about 1300 miles on the KM3’s now. They performed great in mud. A friend had KM’s on his rubicon in a similar size and the KM3’s on mine appeared to shed mud and sand more easily. We were both aired down to about 15psi. Never lost traction, they grip well, I’m pleased with them. Rocky and muddy stream beds, post-flood mud, loose rock on hill climbs, all of it handled well by this tire. Including the flash flood waters in Kanab over the weekend. No trouble handling water on pavement. I don’t have any complaints.

Road noise is a background noise you get used to; not annoying, you can hear it, but it’s typical of a MT.

MPG seems slightly lower than the factory tires but not by much. I can still achieve 20-21 on the highway taking it easy.

I’m a novice at this stuff but I think good tires and airing down go a long ways in capabilities on the trail.

White Mountain is where my Nitto's wall ruptured this Friday
