2019 Ram 1500 — Tire Size, Pressure, Bolt Pattern & Wheel Specs

Quick answer

• OEM tire size (most common): 275/65R18 (new‑body DT); 265/70R17 or 275/60R20 (Classic DS). Optional/upgrade sizes include 275/55R20, 285/45R22, and Rebel off‑road 275/70R18 A/T.
• Recommended cold tire pressure (door placard): Typically 36 psi front/rear for P‑metric 18–20" packages; 39–40 psi on some 20/22" packages; LT off‑road packages may specify ~50–55 psi. Always confirm the driver‑door placard for your exact trim/tire.
• Bolt pattern: DT (new 2019 1500) = 6x139.7 mm (6x5.5). Classic DS (2019 Ram 1500 Classic) = 5x139.7 mm (5x5.5).
• Wheel size (factory): 17x7–8 (Classic DS), 18x8 (DT), 20x9 (DT & DS), 22x9 (DT). Typical OE offset +18 to +20 mm; hub bore ~77.8 mm.
• Load index / speed rating (typical): P‑metric packages usually LI 111–116, speed T–H; off‑road/LT packages vary by load range (check sidewall/placard).
• Spare tire: Full‑size steel spare with matching overall diameter; commonly 275/65R18 on DT packages, or 265/70R17 on Classic DS. Some 20/22" packages still ship with an 18" full‑size spare matched to OD.
• TPMS sensor frequency: 433 MHz (most 2019 Ram 1500 and 1500 Classic). Verify by VIN if replacing sensors.

Tire sizes by trim

Notes

• 2019 was offered as the new‑generation 1500 (DT) and the 1500 Classic (DS). They use different bolt patterns and many different wheel/tire options.
• Always use the exact size and inflation noted on your door placard for the tires currently installed.

Recommended replacement tires

• Value all‑season highway (quiet/long tread): General Grabber HTS60 or Cooper Endeavor Plus — great ride and tread life for daily use.
• Mid‑range A/T (mild off‑road, snow rated): Falken Wildpeak A/T3W or Cooper Discoverer AT3 4S/XLT — strong wet/snow traction with decent road manners.
• Premium touring/light truck: Michelin Defender LTX M/S — excellent longevity, wet braking, and towing stability.
• Off‑road focused A/T: Goodyear Wrangler Duratrac or BFGoodrich All‑Terrain T/A KO2 — aggressive traction; expect more noise/firmness.
• 22" luxury street: Pirelli Scorpion Verde All Season Plus 3 or Bridgestone Alenza AS Ultra — refined ride for 20–22" packages.

Pick the load rating that matches your placard (P‑metric vs LT, and appropriate load index). Upsizing to LT/E for heavy towing will require higher pressures than P‑metric tires for the same load.

When to inflate to max load psi (HD trucks only)

The Ram 1500 is a light‑duty truck. Do not use the sidewall “max pressure” unless you have LT tires and are operating at or near maximum payload/tongue weight. For everyday driving on P‑metric tires, use the door‑placard PSI (commonly ~36 psi). If you install LT tires (e.g., on a Rebel or for towing), inflate based on load charts or the placard for that LT fitment (often ~50–55 psi when loaded), and reduce when unloaded for ride/traction. Never exceed the wheel’s pressure rating.

Lug nut torque & pattern

• Lug pattern: DT = 6‑lug; Classic DS = 5‑lug.
• Torque: 130 lb‑ft (176 N·m) is typical for Ram 1500. Re‑torque after 25–50 miles on new wheels.
• Hardware: M14x1.5 studs, 60° conical‑seat lug nuts.
• Hub bore: ~77.8 mm. OE wheel offset generally +18 to +20 mm.
• Tightening sequence: Use a star pattern (5‑ or 6‑lug) in two to three stages to reach final torque.

Common tire issues for this vehicle

• Inner/outer shoulder wear from misalignment or running leveled/aftermarket suspension without re‑alignment. Check alignment after any suspension change.
• Cupping/feathering on aggressive A/T tread if under‑rotated; rotate every 5–7k miles.
• Harsh ride or tramlining on 22" low‑profile packages; consider moving to 20"/18" for more sidewall if comfort is a priority.
• TPMS service: 2019 typically uses 433 MHz and self‑learns after a few miles, but mixed‑year wheels or aftermarket sensors can cause faults; match frequency and sensor protocol.
• Clearance when upsizing: 33" fits most DT trims stock; 34–35" usually needs level/lift and possible trimming, especially on Rebel with splash guards.
