What size is the thread on a Toyota wheel nut?
The thread size most commonly found on Toyota wheel nuts is M12 x 1.5, but there are exceptions by model, year and market. Verify your specific vehicle before buying replacements.
Wheel nuts connect the wheel to the hub and must match the stud diameter, thread pitch, and seating style. Because Toyota's lineup includes compact cars, hybrids, SUVs and trucks, the lug nut thread size varies. This guide outlines typical sizes and how to confirm yours.
Common lug nut thread sizes in Toyota vehicles
These are the sizes most often encountered across Toyota's current and recent model lineups. Always confirm for your exact vehicle using official specs or by inspecting the OEM hardware.
Passenger cars and crossovers
In the majority of newer passenger cars and crossovers, the lug nuts use a 12 mm stud with a 1.5 mm thread pitch and a 60-degree conical seat.
- M12 x 1.5 — 60-degree conical seat; standard on most modern Toyotas such as Corolla, Camry, RAV4, and many hybrids.
- M12 x 1.25 — found on some older Toyotas or certain markets; less common on current US-spec models.
These configurations cover the bulk of daily drivers; if your vehicle isn't referenced here, check the owner's manual or the service manual for the exact lug nut size.
Trucks and larger SUVs
On larger Toyotas, including some pickups and SUVs, you may encounter a coarser or larger thread. The most common alternative is:
- M14 x 1.5 — used on some larger trucks and SUVs in certain generations; paired with heavier wheels and sometimes different seat designs.
- Other sizes occasionally appear in older or region-specific models; verify with OEM information.
For trucks and large SUVs, always confirm with the exact VIN or the wheel spec sheet before ordering replacements.
How to verify your lug nut thread size
To avoid guessing and ensure you get the correct lug nuts, follow these steps to confirm your vehicle’s lug thread size precisely for your model/year and region.
- Consult the owner’s manual or a Toyota service manual for wheel-thread specifications tied to your model/year and region.
- Inspect the OEM lug nuts themselves; some nuts have the thread size stamped on the nut or on a label included with the wheel set.
- Measure the thread diameter with a caliper and determine the pitch with a thread gauge, or count threads over a measured length to estimate pitch (e.g., roughly 5 threads per 4 cm helps distinguish 1.5 vs 1.25).
- Ask a Toyota dealer, certified tire shop, or the wheel manufacturer using your VIN for the exact lug-thread spec.
- Only use lug nuts that match the thread size, pitch, and seat type for your wheels to ensure proper torque and wheel retention.
Getting the size right prevents cross-threading, wheel loosening, or damage to the hub and wheel assembly.
Summary
In practice, the typical thread size for Toyota wheel nuts is M12 x 1.5, especially on modern passenger cars and crossovers. Some trucks and older or regional models use M14 x 1.5, and a minority may feature M12 x 1.25. When in doubt, confirm via the owner's manual, VIN-specific service data, or an authorized Toyota dealer, and always use the correct seating type and lug nut torque.
