2024 Jeep Grand Cherokee — Tire Size, Pressure, Bolt Pattern & Wheel Specs

Quick answer

• OEM tire sizes (common): 265/60R18, 265/50R20; Summit Reserve: 275/45R21; Trailhawk: 265/60R18 A/T
• Recommended cold tire pressure (door placard): Most trims 36 psi front / 36 psi rear; some 20–21 in packages may list up to 38 psi F/R — always verify your door placard
• Bolt pattern: 5x127 mm (5x5")
• Wheel size/offset (factory): 18x8 (+50 mm), 20x8.5 (+55 mm), 21x9 (+50 to +53 mm)
• Load index & speed rating (OEM typical): LI 107–111, Speed H–V (many 20–21 in fitments are XL)
• Spare tire: Compact temporary spare commonly T135/80R18 or T145/80R18; some trims have full-size spare; some 4xe models use an inflator kit — check cargo well
• TPMS sensor frequency: 433 MHz (auto-learn after driving)

Tire sizes by trim

Notes:

• Availability varies by package (off-road, tow, appearance) and powertrain (including 4xe). Always confirm on your door placard and current wheel/tire.
• Factory offsets are generally +50 to +55 mm with 71.5 mm hub bore and M14x1.5 studs.

Recommended replacement tires

Prices vary by size; typical street pricing shown per tire.

• Premium all-season touring: Michelin CrossClimate 2 SUV — outstanding wet/snow braking and comfort. Approx. $260–$330 (18–20 in), $360–$420 (21 in).
• Highway all-season: Continental CrossContact LX25 or Pirelli Scorpion AS Plus 3 — quiet, long treadlife. Approx. $220–$310 (18–20 in), $320–$400 (21 in).
• Durable light-truck all-season: Michelin Defender LTX M/S2 — excellent wear and towing stability. Approx. $250–$330 (18–20 in), select sizes in 21 in $360+.
• All-terrain (Trailhawk/off-road friendly): Falken WildPeak A/T Trail or BFGoodrich Trail‑Terrain T/A in 265/60R18 — balanced on‑road manners. Approx. $210–$290.
• Value all-season: Cooper Endeavor Plus or Hankook Dynapro HP2 — solid performance for less. Approx. $180–$260 (18–20 in).

Tip: Match the load index/speed rating to or above your OEM (commonly LI 107–111, H–V; many 20/21 in are XL). If you tow frequently, consider LT or XL options with higher load capacity where available.

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

This does not apply to the 2024 Grand Cherokee. Use the door‑placard pressures (typically 36 psi F/R; some 20–21 in packages up to 38 psi). Do not inflate to the tire’s sidewall “max pressure” unless specified by a load/inflation chart for LT tires — overinflation can reduce grip and increase wear.

Lug nut torque & pattern

• Lug nut torque: 129 lb‑ft (175 N·m) is typical for this chassis; re‑torque after ~50 miles on newly installed wheels.
• Stud/thread: M14 x 1.5; 60° conical seat lug nuts.
• Bolt pattern: 5x127 mm (5x5"). Center bore 71.5 mm.
• Tightening sequence: 5‑lug star pattern (1‑3‑5‑2‑4) to ensure even clamping.

Common tire issues for this vehicle

• Inner shoulder wear on front tires if alignment is off or pressures are run low. Rotate every 5,000–7,500 miles and request a 4‑wheel alignment annually or after impacts.
• Sidewall bubbles and bent rims are more common with 20–21 in low‑profile sizes on rough roads. Consider an 18 in winter/off‑road set if you face potholes or trails.
• All‑terrain OE/aftermarket tires (Trailhawk) can develop cupping if not rotated on schedule; keep pressures at placard and rotate on time.
• TPMS: 433 MHz sensors auto‑learn after a short drive; mixed sets must all be 433 MHz. Aluminum valve stems are common — use compatible caps and avoid galvanic corrosion.
• Towing/heavy loads: Stay at placard pressures unless your tire manufacturer provides a load chart for your exact tire; keep rear alignment in spec to avoid feathering when loaded.
