EDIT: you all know that you should only buy Wildpeaks from approved distributors because there are tires that were supposed to be destroyed but are sold by others, right? There used to be a warning on the Falken website though I no longer see it. Hopefully the defective tires are all gone. I use Discount Tire.
Ok, I am a bit short of 15,000--but close.
Vehicle: 4R TRDOP non-kdss, March 2018. Wildpeaks a week later.
P 265 70 17.
Total mileage: close to 15,000.
Dirt use: over 1,500 miles, 61 trails, 70 runs.
Notable trails: Backaway to Crown King, Broken Arrow, Fins and Things, Tower Arch, Maze district of Canyonlands, Montana mountain trails.
Road pressure: 33-35 psi. Offroad: 28-35. Yup. Only aired down to 21 for Double Crater climb near Flagstaff.
Overall impressions: best I have had (much better than Toyo AT II, BFG KO2s, Conti AT, Geolander ATS).
Rock: superb. They are not as strong as MTs or select D/E load ATs, but they are strong enough, even at street pressures. One puncture due to high pressures, good speed, and many sharp small rocks on an easy desert trail. Bad luck more than anything. Incredible traction in rock, at least coupled with a TRDO/TE
Dirt: great in 4H. Coming from a Subaru, handling on dirt leaves a lot to be desired on a high center of gravity 4x4, but grip is great in 4H. No serious complaints.
Sand/snow: no complaints. Mud: meh, not a fan of mud. Avoid it when I can.
Road performance: No appreciable difference from the stock tire on road. No appreciable mpg drop either.
Road comfort: Impressively quiet (no noise) and comfy (no discernible harshness).
Why P metric? Because P metric is far superior almost all of the time. It means no airing down for comfort and much less airing down for traction than an E-load tire meant for super duty trucks. It means minimal impact on acceleration, mpg, and road comfort. The one place where the E-load version may pay off is the Sonoran desert but even so I would rather replace a tire once a year than put up with all the E-load compromises on daily basis.
Update to the above review. In sum, I have been arguing that a good P metric is better overall choice for a multi-purpose rig, with the noted exception bolded. I have also been arguing that P metric should NOT be aired down except when really needed (deep sand).
Well, I proved myself right on the latter count today. To preempt tread puncture in the same kind of terrain as the one referenced above, I aired down to 25, noting that the bulge is quite big for that pressure (like a D load KO2 at 15 or so). 6 miles later we blocked a narrow section of trail, halting 3 UTVs coming the other way while replacing a tire destroyed by a sidewall split bead to shoulder, gnarly! We were moving at a good pace and I am sure that did not help.
Let's look at some numbers:
I don’t have a P/LT breakdown by state, but overall it goes like this with 75% P-metric and the rest D-load KO2s. This is unpaved mileage:
Southern Utah 2800 miles no punctures, no sidewall cuts
Colorado 750 same
Montana 600 same
AZ: NOT Sonoran desert 1200 same
AZ: Sonoran desert 600 1 puncture and 1 sidewall cut
CA and NM 140 no issues, light duty only
Now before someone starts yelling “told you so” bear in mind that the various 2-ply sidewall tires have pretty similar sidewall thickness from P to E. Three-ply sidewall Ds and Es like the KO2s have much thicker sidewalls, no question about that.
For now, I think I will stick to 33 psi.
EDIT: so, yes, two weeks later we went there, did not air down, and had
no issues at all completing the trail and then driving another one. We drove a total of 48 miles through the desert over the same small, sharp rocks. No issues.
EDIT 2:
another 150sh miles of very rough desert terrain at 33 psi and no issues. The tire has great flex at 33 psi when over a rock.
