2018 Nissan Titan — Tire Size & Pressure

Quick answer

• OEM tire size: 265/70R18 (S, SV); 275/65R18 (PRO-4X); 275/60R20 (SL, Platinum Reserve; some SV Midnight Edition)
• Recommended cold tire pressure (door placard): typically 35 psi front / 35 psi rear (some trims list 35–36 psi). Always follow your door placard.
• Bolt pattern: 6x139.7 mm (6x5.5")
• Wheel size and offset: 18x8J or 20x8J; offset generally +20 to +30 mm; hub bore ~77.8 mm; lug thread M12 x 1.25
• Load index / speed rating: P-metric tires commonly LI 113–117, S–T speed rating (varies by size and tire model)
• Spare tire size: usually a full-size 265/70R18 on a steel wheel, even on 20"-wheel trims (verify on placard)
• TPMS frequency: 315 MHz for North America (some non-U.S. markets use 433 MHz)

Tire sizes by trim

Notes:

• The above reflects common U.S. fitments. Always confirm on your driver’s door placard and in the owner’s manual.
• Titans equipped with tow or appearance packages may share tires/wheels across trims.

Recommended replacement tires

Choose based on how you use your Titan and your typical climate. Prices vary by size and retailer; ranges below are estimates per tire in these sizes (265/70R18, 275/65R18, 275/60R20).

• Budget ($):

  • Hankook Dynapro HT RH12 or Dynapro AT2: dependable highway/all-terrain manners; approx. $160–$230
  • General Grabber HTS60: stable highway handling and good treadlife; approx. $170–$240

• Mid-range ($$):

  • Falken WildPeak A/T3W: strong snow/wet grip and off-road capability; approx. $210–$290
  • Continental TerrainContact H/T (or A/T): refined ride with excellent wet braking; approx. $220–$300

• Premium ($$$):

  • Michelin Defender LTX M/S: benchmark highway all-season with long treadlife; approx. $260–$360
  • Bridgestone Dueler A/T Revo 3 (A/T) or Alenza AS Ultra (H/T): confident wet/dry grip; approx. $250–$350
  • Goodyear Wrangler Workhorse AT: modern A/T with winter capability; approx. $230–$320

Tip: If you tow frequently, consider LT-metric options (e.g., LT275/65R18 E-load) for stronger sidewalls. Follow the load/inflation tables and your placard.

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

The standard 2018 Nissan Titan (half-ton) uses P-metric tires and typically should be kept at the placard pressure (around 35 psi). Do not inflate to the tire’s sidewall “max pressure” for normal driving.

For the Titan XD (heavy-duty variant) equipped with LT E-load tires, the sidewall may list up to 80 psi. Only approach those higher pressures when carrying or towing near the truck’s GVWR/GAWR and when specified by the door placard or a load/inflation chart for your exact LT size. Many XD placards call for substantially lower everyday pressures (often in the 60–65 psi range, size-dependent). Overinflation when unloaded leads to harsh ride and uneven wear.

Lug nut torque & pattern

• Lug/bolt pattern: 6x139.7 mm (6x5.5"); hub bore ~77.8 mm; lug thread M12 x 1.25
• Torque spec: typically 98 lb-ft (range 95–100 lb-ft). Re-torque after 50–100 miles on new installations.
• Tightening pattern: star/alternate pattern across the 6 lugs to seat the wheel evenly.

Common tire issues for this vehicle

• Outer-edge wear: often from underinflation—keep all four at the door-placard PSI, check monthly and before towing trips.
• Cupping/feathering on A/T tires (PRO-4X common): aggravated by worn shocks or misalignment; rotate every 5–7k miles and align annually or after suspension work.
• Highway vibration (20" wheels): large-diameter assemblies may require road-force balancing; ensure hub-centric fit and correct torque.
• TPMS light in cold snaps: pressures drop ~1 psi per 10°F; set cold at placard PSI, not “hot.”
• Slow bead leaks on older chrome-clad wheels: corrosion at the bead can cause gradual loss—clean/seal beads during tire service if noted.
