Toyota RAV4 Rim Bolt Pattern: When shopping for new wheels, the bolt pattern (also known as lug pattern) is the primary criterion that will determine whether or not a wheel fits your vehicle. The bolt pattern is the layout of the mounting holes at the center of the wheel.
Bolt patterns are relatively easy to determine, especially for standard 4- or 5-lug designs. However, it can become difficult when dealing with odd number patterns like 5×4.5.
Bolt Pattern
The bolt pattern, also known as lug pattern, is the primary criterion that determines whether a wheel will fit your Toyota RAV4. It indicates the arrangement of holes in a circle around the center of the wheel. The first number is the total number of bolt holes and the second number indicates the size of those holes, which is measured in inches (imperial) or millimeters (metric). Although retailers and Toyota dealerships will know your car’s bolt pattern, if you’re purchasing wheels on your own, it’s essential to understand this measurement. Otherwise, your new wheels may never attach to the vehicle. The bolt pattern on a Toyota RAV4 is 5×4.5 inches (imperial) or 5×114.3 millimeters (metric).
Knowing your car’s bolt pattern makes it much easier to choose the right wheel.
Lug Nut Size
When swapping out your wheels it is very important that you use the correct lug nut size as well as torque them to manufacturer specs. The wrong lug nuts can cross thread and break the wheel stud. Not only that but not torqueing them down properly can cause the lug nuts to loosen over time, possibly resulting in your wheels falling off your vehicle on the road.
There are several different types of lug nuts, and they vary in size, shape, taper, and thread pitch. The type you choose will depend on the style of wheels, application and purpose.
Hex nuts are the most common and feature a hex-shaped head that threads onto a matching wheel stud. They come in a variety of finishes and styles, and some are even anodized to resist corrosion and rust.
Another common type of lug nut is the spline drive. These have a ridged or grooved head that fits around the hex socket, and they require a special tool for removal. They are often used on racing wheels for their strength and security.
The last type of lug nut is the conical seat, which has a taper that helps to center the wheel on the hub and reduce loosening due to fretting-induced precession. This type is often used in applications that call for more thread engagement, such as when using wheel spacers.
Lug Nut Thread Pitch
The lug nuts on your car’s wheels (also called wheel bolts) screw into threaded wheel studs which in turn screw into tapped holes in the vehicle’s wheel hub. Lug nut thread pitch, which is the distance between individual threads, can be measured manually by counting the number of peaks on a nut or with a digital caliper.

If the lug nut is too loose, it can pinch and not engage the stud threads; if the lug nut is too tight, it may cause the stud to deform under load, which reduces the wheel’s structural integrity. The lug nut’s thread pitch is also important as it determines how fast the nut can be tightened.
There are different types of lug nuts, which are available in different finishes and platings. Some are open-ended, which allow the stud threads to protrude through them; others are closed or “acorn” style on both ends and require a hex key for removal. Some lug nuts are even made of titanium or chrome plated for corrosion resistance and to provide a show quality appearance. Getting all these dimensions and specifications straight is essential, as using the wrong lug nuts can cause your wheels to fall off while driving or even damage the wheel.
Lug Nut Diameter
The number of lug nuts used depends on the amount of force that the wheel has to deal with. For example, heavier wheels require more lug nuts to handle the extra torque. Also, the diameter of the wheel has an impact on the number of lug nuts used. Since a single bolt can only bear a certain amount of force, the engineers use a few lug nuts to support the weight and torque of the wheel.
Lug nut thread size and pitch is another important factor. The thread size measures the distance between each individual thread on the wheel stud and is usually expressed in terms of “threads per inch”. To get the thread diameter, measure the thread’s peak-to-peak. A mismatched thread size can result in poor engagement and even damage the wheel stud.

The three most common types are cone (also known as acorn nuts), ball, and flat seat. Conical seat lug nuts have a beveled 60 degree angled surface and are the most popular choice for aftermarket wheels. Mag seat lug nuts are designed to be bonded to a flat washer and are typically used on semi-trucks. Flat seat lug nuts have a flat surface and are bonded to the rim with a separate washer.
