The lug nuts on a 2021 Honda Pilot are M12 x 1.5 with a conical (acorn) seat, and you’ll typically use a 19 mm socket. There are five lug nuts per wheel, matching a 5 x 120 mm bolt pattern, with a common torque target around 80 ft-lbs (approximately 108 Nm). Always verify these specs in your owner’s manual or on the door jamb sticker for your exact trim and wheel setup.
In more detail, the 2021 Pilot’s wheel assemblies use standard hardware designed for a five-lork pattern and factory wheel sizes. If you’re replacing wheels or lug nuts, ensure the new hardware matches the factory thread size, seat type, bolt pattern, and torque specifications. Variations can occur with aftermarket wheels, so confirm compatibility before purchasing replacements.

Installation and safety tips
Torque and follow-up maintenance
When installing wheels, torque lug nuts to the vehicle manufacturer’s specification, typically around 80 ft-lbs (approximately 108 Nm) for the Pilot. After a wheel change, re-torque after a short break-in period (often 50–100 miles or 80–160 km) to ensure proper seating. Do not lubricate lug studs with anti-seize compounds unless expressly directed by Honda, as lubrication can alter the effective torque. Use a properly calibrated torque wrench and a quality 19 mm socket for accurate installation.
Summary
The 2021 Honda Pilot uses five lug nuts per wheel with M12 x 1.5 thread, conical seat, 19 mm socket, and a 5 x 120 mm bolt pattern. Typical torque is around 80 ft-lbs (about 108 Nm), but always verify with the owner’s manual or door sticker for your exact trim. Using the correct hardware and proper torque ensures safe wheel mounting and proper alignment.
