If you drive a Toyota Prius, you may want to know what size of lug nuts you require for your wheels. Lug nuts are the metal parts that attach the wheels to the hub, and they differ in sizes and shape depending on the car model and year. It is essential to know the suitable lug nut size for your Toyota Prius because it can prevent issues such as damaged threads, loose wheels, or scratched rims.
In this article, we will show you how to determine the suitable lug nut size for your Toyota Prius model and year, how to select the best lug nut socket size for your Toyota Prius lug nuts, and how to fasten your Toyota Prius lug nuts correctly.
How to Determine the Suitable Lug Nut Size for Your Toyota Prius Model and Year?
The lug nut size for a Toyota Prius depends on two factors: the bolt pattern and the thread pitch. The bolt pattern is the number and arrangement of holes on the wheel hub that match the studs on the axle. The thread pitch is the distance between the threads on the lug nut or stud.
The bolt pattern and thread pitch for a Toyota Prius change depending on the model and year.
| Year | Bolt pattern | Number of lugs | Thread size | Thread pitch | Center bore |
| 2021-2022 | PCD 5×100 | 5 per wheel | M12 x 1.5 | 1.5 | 54.1 mm |
| 2018-2020 | PCD 5×100 | 5 per wheel | M12 x 1.5 | 1.5 | 54.1 mm |
| 2016-2017 | PCD 5×100 | 5 per wheel | M12 x 1.5 | 1.5 | 54.1 mm |
| 2004-2015 | PCD 5×100 | 5 per wheel | M12 x 1.5 | 1.5 | 54.1 mm |
| 2003 | PCD 4×100 | 4 per wheel | M12 x 1.5 | 1.5 | 54.1 mm |
| 2001-2002 | PCD 4×100 | 4 per wheel | M12 x 1.5 | 1.5 | 54.1 mm |
You can also use a ruler or a caliper to measure the bolt pattern and thread pitch of your Toyota Prius lug nuts. To measure the bolt pattern, you need to measure the distance between two opposite holes on the wheel hub, or the diameter of a circle that passes through all the holes. To measure the thread pitch, you need to measure the distance between two adjacent threads on the lug nut or stud.
How to Select the Best Lug Nut Socket Size for Your Toyota Prius Lug Nuts?
The lug nut socket size is the size of the tool that fits over the lug nut and allows you to tighten or loosen it with a wrench or a torque wrench. The lug nut socket size for a Toyota Prius is usually expressed in millimeters (mm) or inches (“).
The official socket size for a Toyota Prius lug nut is 21 mm, but some people have shown that 13/16″ will also work, although it may be a bit tighter. You can use either one, but make sure that it fits well and does not slip or damage the lug nut or rim.
You can also use a universal socket that can adjust to different sizes of lug nuts, but be careful not to over-tighten them as they might not be as precise as a fixed-size socket.
How to Torque Toyota Prius Lug Nuts?
Fastening your Toyota Prius lug nuts means applying a specific amount of force to them to make sure that they are properly secured and prevent them from loosening or breaking due to vibration, heat, or corrosion. Fastening your Toyota Prius lug nuts also helps to prevent uneven wear and tear on your tires, brakes, and suspension.
The recommended torque for your Toyota Prius lug nuts is 103 Nm, which is equivalent to 76 ft-lbs or 91 in-lbs. You can use a torque wrench to apply this amount of force to each lug nut in a star pattern, starting from the center and moving outward.
You should also check your Toyota Prius lug nuts periodically and re-fasten them if necessary, especially after changing tires, driving on rough roads, or experiencing extreme temperatures.
