What is the thread pitch of a Lexus IS250?
The thread pitch of the Lexus IS250’s wheel hardware is M12x1.5 (a 12 mm stud with 1.5 mm thread pitch). In practical terms, this pairs with a five-lug wheel setup on a 114.3 mm bolt circle and standard lug nuts with a 60-degree conical seat designed for M12x1.5 threads.
Core specifications for wheel mounting
These are the essential hardware specs you’ll need to confirm when buying wheels or lug nuts for the IS250.
- Bolt pattern: 5 on 114.3 mm (5x114.3).
- Wheel stud diameter: M12 (12 mm).
- Thread pitch: 1.5 mm (M12x1.5).
- Lug nut seat type: 60-degree conical seat (standard on Lexus/Toyota wheels).
- Thread direction: right-hand threads (standard).
In short, the IS250’s wheel mounting uses M12x1.5 threads on a 5x114.3 bolt circle with conical lug nuts, which is the baseline configuration for most factory and aftermarket wheels.
How to verify your IS250's thread pitch
If you want to double-check the exact spec for your car, use these methods before purchasing new wheels or lug nuts.
VIN-specific considerations
Vehicle identification reveals region, production date, and variations that can affect bolt pattern and lug nut specs. Always refer to your VIN's build sheet or dealer records for the precise numbers.
- Check the owner's manual or a dealership parts diagram for your model year.
- Inspect a current wheel stud or lug nut on the vehicle for markings like M12x1.5.
- Consult a trusted tire or wheel retailer with your VIN to confirm exact specs for your build.
- When in doubt, bring a sample lug nut or wheel from your car to a shop for measurement and confirmation.
Verifying the thread pitch and bolt pattern helps ensure proper fitment and safe wheel installation, especially when mixing OEM and aftermarket components.
Summary
The Lexus IS250 uses M12x1.5 thread pitch on its wheel studs, with a 5x114.3 mm bolt pattern and 60-degree conical lug nut seats. These are the baseline specs you should rely on when selecting wheels and lug nuts, though you should confirm with your exact model year and vehicle configuration if you plan to make changes.
