All-Terrain Tires for Power Wagon (BFG KO2 / Falken AT3W / Toyo AT3)
Factory 33s on the Power Wagon are LT265/70R17 (Goodyear Wrangler DuraTrac). When they wear out, the upgrade most owners actually want is a 33"–34" all-terrain — quieter on highway, better wet/snow than the DuraTrac, and no need to re-gear. KO2 is the reference, Falken AT3W is the value pick, Toyo AT3 is the premium choice.
The Power Wagon comes from the factory with a Goodyear Wrangler DuraTrac in LT265/70R17 — a hybrid AT/MT that's surprisingly capable but loud on highway and short-lived (40k miles is typical). When you're shopping replacements, the four mainstream AT options that actually fit factory wheels and clear the fenders with no rub are: BFG KO2, Falken Wildpeak AT3W, Toyo Open Country AT3, and Nitto Recon Grappler.
BFG KO2 (LT285/70R17 = 32.7") — the AT reference standard. Aggressive tread for an AT, excellent snow rating (3PMSF), 50k-mile typical life on a Power Wagon. Loudest of the four on highway above 65 mph. About $380/tire = $1,520 for a set of four.
Falken Wildpeak AT3W (LT285/70R17 = 32.7") — same size, ~25% cheaper, slightly less aggressive shoulder lugs, comparable highway noise, 60k+ life. The value choice — this is what most Power Wagon owners on the forums end up with.
Toyo Open Country AT III (LT295/70R17 = 34.3") — biggest of the four, premium tier. The slightly bigger 34.3" diameter is the largest you can fit on factory fenders + factory wheels without trimming. Quieter than KO2, similar life, 30% more expensive. The choice if you want max diameter without going to 35s (which requires fender trimming and 4.56 re-gear).
Nitto Recon Grappler A/T — newer entry, slightly more aggressive shoulder than KO2, decent snow, similar price to KO2. Smaller user base on Power Wagons so less long-term data, but well-reviewed.
For a moderate-trail Power Wagon build, the Falken AT3W is the value sweet spot. For overland, the Toyo AT III's larger diameter is worth the premium. For rock-crawler builds, skip the AT and go straight to 37" MTs (see pw-tires-mt).
The Power Wagon weighs ~6,900 lb and has a front GAWR around 4,500 lb, so tire load rating is not optional. Every size above must be LT-metric, Load Range C or higher — never run a P-metric (passenger) tire on this truck. The factory DuraTrac is Load Range C; matching or exceeding it keeps you inside the door-jamb load spec.
- Factory 33s (LT265/70R17, ~31.6" measured): drop-in, no changes.
- 285/70R17 (~32.7"): clears the factory fenders at full lock and full stuff with no trimming on a stock-height or leveled truck. This is the safe one-up size.
- 295/70R17 (~34.3"): the largest that fits factory wheels and fenders without trimming. Watch the front inner sidewall at full lock — on a leveled truck you may catch the lower control arm. A 1.25" hub-centric spacer (pw-wheel-spacers) cures it.
- 35s and up: need a real lift (pw-lift-mid-3in) plus spacers, and you cross the re-gear line below.
Set cold pressure by load, not by the 80 psi on the sidewall. For an unloaded-to-lightly-loaded Power Wagon on 285s, most owners run ~45-50 psi front / 40-45 psi rear and verify with a chalk-line test across the tread. Always torque to 140 lb-ft on the M14x1.5 lugs and re-torque after the first 50 miles.
Honest answer: not for any AT size on this list. The Power Wagon's factory 4.10 axle ratio (with the 33" factory tire) tolerates a one-up to 285/70R17 or even the 34.3" Toyo without a meaningful drivability hit — you lose a sliver of low-end and the speedo reads ~3% slow. The 6.4L Hemi has the torque to pull a 34" tire on 4.10s all day.
You cross into re-gear territory at 37s, where the effective ratio drops enough to hurt towing and trans temps. If a 37" build is the goal, plan the tire and the 4.56 regear together (see pw-regear-456) rather than running big tires on stock gears and cooking the transmission on grades. For everything on this AT list, keep your money and stay on the factory gears.
Why it works
- Direct factory-size swap or one-up — no fender trimming, no re-gear
- Better wet/snow than the factory DuraTrac
- 50-60k mile typical life on Power Wagon weight
- Quieter highway noise than the factory DuraTrac (true of all four)
Trade-offs
- KO2 is loud above 65 mph
- Largest AT (Toyo 34.3") still needs LT load range — heavier than factory
- No tire is as light-weight friendly as a passenger-rated tire (Power Wagon is heavy, you need LT-rated)
- Factory wheel offset (-25mm) limits tire width — wider than 285 needs spacers or new wheels
Tools required
- torque wrench (140 lb-ft for the M14x1.5 lugs)
- tire-pressure gauge
