2024 Ram 2500 — Tire Size & Pressure Guide

Quick answer

• OEM tire size (most common): LT275/70R18 E; optional LT285/60R20 E; Power Wagon: LT285/70R17 D
• Recommended cold tire pressure (door placard, typical):
  • Most 18"/20" E‑load trims: ~60 psi front / 80 psi rear
  • Power Wagon (17" D‑load): ~65 psi front / 65 psi rear
  • Rebel/off‑road 18" A/T: ~60 psi front / 65–80 psi rear (varies by GVWR and axle)
  • Always verify your specific placard on the driver’s door jamb
• Bolt pattern: 8x165.1 mm (8x6.5")
• Wheel size (factory): 17x8 (Power Wagon), 18x8, or 20x8; factory offsets typically +20 to +50 mm depending on package
• Load index / speed rating (typical):
  • LT275/70R18 E: 125/122 R or S
  • LT285/60R20 E: 125/122 S
  • LT285/70R17 D (Power Wagon): 121/118 R
• Spare tire: Full‑size LT spare matching the OEM diameter (17", 18", or 20" depending on trim)
• TPMS frequency: 433 MHz on 2019–2024 Ram HD (verify by sensor PN when replacing)

Tire sizes by trim

Note: Exact equipment varies by axle ratings, engine (6.4 Hemi vs. 6.7 Cummins), and packages. Always confirm the door placard and build sheet.

Recommended replacement tires

• Value highway/all‑season (E‑load): Firestone Transforce HT2 or General Grabber HD – usually lower cost; dependable for work trucks that live on‑road.
• Mid‑tier all‑terrain (E‑load): Falken WildPeak A/T3W, Cooper Discoverer AT3 XLT, or Toyo Open Country A/T III – strong snow traction and towing stability with good ride quality.
• Premium highway/towing (E‑load): Michelin Defender LTX M/S2 or Bridgestone Duravis R500 HD – excellent tread life, wet braking, and stability under heavy tongue weight.
• Off‑road/overland: BFGoodrich All‑Terrain T/A KO2 or Goodyear Wrangler Duratrac – popular for Rebel/Power Wagon owners; pick the correct load range (D for Power Wagon OE feel; E for heavier payloads).

Tip: Match or exceed the OEM load index. Most 2500 trims require LT Load Range E; the Power Wagon uses LR D from the factory for ride/articulation but can run E if you need more payload.

When to inflate to max load psi (HD trucks)

Use the sidewall “max” pressure (often 80 psi for LR E) only when the truck is at or near its Gross Axle Weight Ratings—e.g., heavy bed payload, slide‑in camper, or substantial trailer tongue/pin weight. For daily unloaded driving, follow the door placard or consult tire load‑inflation charts to fine‑tune within safe limits. Over‑inflating when empty can cause harsh ride, reduced wet traction, and center tread wear.

Lug nut torque & pattern

• Lug pattern: 8 lugs on 8x165.1 mm (8x6.5") hub.
• Lug nut thread: M14x1.5 (typical for 2019+ Ram HD).
• Torque: 130–150 ft‑lb is the common range; many factory specs are near 130 ft‑lb. Re‑torque after 50–100 miles on new wheels or rotations.

Common tire issues for this vehicle

• Uneven rear wear when unloaded: Running 80 psi rear with no load can crown the tread. Drop to placard or load‑chart‑appropriate psi when empty.
• Cupping/feathering on off‑road trims: Aggressive A/T tread on Power Wagon/Rebel can cup if shocks are tired or rotations are stretched. Rotate every 5–7.5k miles.
• Front‑end wear and shimmy: Solid‑axle HDs can develop toe or track bar issues that show up as inner/outer wear or shimmy. Check alignment and steering components if wear is uneven.
• Tire fitment rub with larger sizes: Sizes beyond ~35" equivalent often contact control arms or splash liners without proper offset. Keep factory‑style positive offset for towing stability.
• TPMS service: 2024 uses 433 MHz sensors; mismatched frequencies or wrong clone/ID procedures can trigger faults after wheel swaps.
