The Power Wagon's 8x165.1 (8x6.5") bolt pattern is shared with most 3/4-ton and 1-ton RAM trucks, giving you a wide selection — but load rating is the specification that matters most here, and many aftermarket wheels skip the engineering that a truck with an 8,510 lb GVWR demands.
Load rating is the non-negotiable spec for the Power Wagon. GVWR of 8,510 lbs divided by four wheels = 2,127 lbs per wheel minimum. The industry standard recommendation for a margin of safety puts the target at 3,000–3,500 lbs per wheel minimum for a truck in this weight class, especially under payload or towing. Many wheels marketed for trucks carry load ratings of 2,500 lbs that are technically sufficient but leave no margin for dynamic loads (trail impacts, towing with tongue weight, etc.). Before finalizing any wheel purchase, look up the load rating in the manufacturer's spec sheet — if it isn't published, that's a reason to look elsewhere.
Offset matters on the Power Wagon. The factory wheels run a +18mm offset; staying in the +10 to +25mm range keeps the wheel center close enough to factory geometry that you won't need wheel spacers and won't strain the wheel bearings at the extended scrub radius of an aggressive negative-offset setup. Wide-stance wheels (deep negative offset, like 20x14) push the tread out past the fender, which requires flares or trimming — not the call for a trail-daily truck.
The factory Power Wagon wheel is a 17x8 — not an 18 or 20 like other Ram 2500 trims — because Ram sized it around the 33" Goodyear Wrangler DuraTrac (LT285/70R17) and the sidewall that tire needs off-road. That logic still applies when you upgrade. Staying at 17" with a 35" tire (LT315/70R17 territory — see the tire fitment guide) preserves the deepest sidewall, airs down the best, and has the widest selection of genuinely trail-focused tires. Method's 308 in 17x8.5 is the pick if the truck sees rocks.
20x9 is the most popular street-side upgrade. With a 35"–37" tire it keeps an acceptable sidewall while opening up more all-terrain and hybrid tire selection, and it fills the wheel wells visually. Method 308 in 20x9 ($185/wheel) publishes clear load ratings and has a strong track record on 3/4-ton builds. Fuel Maverick D538 ($175) is a styling-forward choice with adequate ratings. Black Rhino Armory ($165) is the value end of the quality tier. American Force ($350) is for owners prioritizing appearance — billet construction, high polish, and the least sidewall of the bunch. 18" splits the difference and is a legitimate middle path, though tire selection in LT sizes is thinner than at 17 or 20.
What you give up moving from 17 to 20: roughly two inches of sidewall per side at the same overall tire diameter. That's two inches less air cushion between rim and rock, less bulge when aired down, and a harsher ride on washboard. For a truck that wheels hard enough to air down regularly, that trade runs the wrong direction — which is also the case for going further into beadlock territory at 17".
A cast 20" wheel in this class runs 38–45 lbs bare versus roughly 30–34 lbs for the factory 17 — add a 37" tire and you can put 15+ lbs of unsprung, rotating mass at each corner over stock. On a truck this heavy the shocks pay the bill: more unsprung mass means more heat in the dampers on washboard and faster fade on long corrugated roads. It also lengthens braking distance slightly and dulls throttle response, which stacks with the effects covered in the tire guide. Check the published wheel weight next to the load rating; among wheels with equal ratings, buy the lighter one.
