The wheel size also includes its width and offset. The width is the distance from each bead seat (from inside to the outside). The offset determines how the wheel and tire set aligns with the wheel well.

PCD stands for Pitch Circle Diameter and essentially is the measurement of how many wheel nuts or wheel bolts your vehicle has on each wheel and how far apart those nuts or bolts are placed in mm.

Put simply, to find if your wheels will fit your car, measure the distance from your wheel's center point to where it is mounted. This is the offset. Add that to half your wheel's width to find the back space and subtract it to find the front space. Compare this to your wheel well to see if it fits.

The adapter bolts… Q: My bolt pattern is 4x100 and the wheel i want to put on my car are 4x108 will these fit? A: Yes. These are the correct adapters for your 4x100 car and use you 4x108 wheels!

Measure the distance from the floor to the straight edge and divide by two. That calculates the centerline of the wheel. If the centerline number is smaller than the hub measurement, offset is positive; if it is larger, offset is negative.

Even if the tire and wheel have enough clearance, the wrong offset can decrease vehicle stability. Generally, with new wheels, you don't want the new offset to be more than 5 millimeters different from the old offset.

You're right, the way to do it is by using an adapter...it is also a spacer. spacers as such are common. hub adapters are somewhat too, but used only on those cars on which finding alloys is an issue. The adapters are said to transmit all shock to the hub, and it's known to bend the lugs.

Hub adapters, often also referred to as PCD adapters or PCD hub adapters, allow you to fit alloy wheels to your vehicle when the PCD and fitment doesn't match.

How do you read PCD on rims? ›

PCD (Pitch Circle Diameter)

Is the diameter of the circle formed by the holes on your wheels in millimeters. They are usually written in the hundred or near the hundred beside the number of holes such as: 4×100, 4×120. In Japan, this number is followed by the number of holes (100-4h, 120-4h).

Positive Offset: In a wheel with positive offset, the mounting surface of the wheel is to the outside of the wheel (on the street side). This is the most common scenario for newer, OEM setups.

The offset is 2 inches, or about 50 millimeters. If the number is higher than half of the width, this is a positive offset. If it's lower than half the width, it's a negative offset.

Positive Offset

A 20mm offset means the wheel face is more toward the outside of the vehicle than a 1mm offset.

VW T4 15 Inch Steel Wheels.

The 4 X 108 bolt pattern is common to FORD, MERCURY, SAAB, AUDI, VOLVO, PORSCHE, PEUGEOT, (older) ALFA ROMEO and OLDSMOBILE vehicles.

It should go without saying, but all wheel drive and four wheel drives vehicles should have the same tire size on all four wheels. Having different sizes on some four wheel and all wheel drive vehicles can actually do damage to the vehicle.

Bolt pattern or bolt circle is the diameter of an imaginary circle formed by the centers of the wheel lugs. Bolt patterns can be 4-, 5-, 6-, or 8-lug holes. A bolt circle of 4x100 would indicate a 4-lug pattern on a circle with a diameter of 100mm.

Positive offset means that the mounting plate is in the outside half of the wheel, toward the wheel face. Most OEM wheels, and most wheels in general, will have a positive offset.

Example 1: +25 mm offset = The center of the wheel is 25 mm closer to the outside, or curbside, of the wheel. (+) offset pushes the wheel farther into the caliper/brake. Extreme positive offset can result in poor overall fitment due to the wheel tucking, or even worse, suspension rubbing!

What is better negative or positive offset? ›

The correct backspacing will allow enough room for the suspension, brakes and steering systems to operate without interference from the wheel. Remember, there's a direct correlation between backspacing and offset. A positive offset creates more backspace, while a negative offset reduces backspace.

On most OEM wheels, offset is positive (contact patch slightly inboard), and it can have a major effect on steering feel and stability during acceleration and braking.

PCD is the amount of mounting holes in the wheel and the width apart of the mounting holes. Offset is the distance of the hub mounting surface to the centre line of the wheel, see below for a full explanation. These measurements are required when fitting aftermarket or non standard wheels.

For your safety, and for the optimal ride, your rim width and tire size must be compatible. Why? Because the rim width has a direct impact on your tire's contact patch, which changes how the tire interacts with the road and how your vehicle handles.

Width and diameter are the two factors that determine tire and rim compatibility. For diameter you'll need to be sure that your tires and wheels are an exact match, e.g. a 215/65R17 tire will only fit on a 17" diameter wheel. There's a bit more flexibility when it comes to wheel widths.

The two easiest ways are to check the sticker plate in your car, it should be located inside the driver side door, or look online for the vehicle specifications for your exact make and model. That should tell you the standard rim size.

The offset of a wheel is the distance from its hub mounting surface to the centerline of the wheel. The offset can be one of three types (measured in millimeters).* "The offset of a wheel is the distance from its hub mounting surface to the centerline of the wheel."

It's important that the studs on these adapters are strong enough as that of the factory item to be able to take the load. I have seen aftermarket local studs, inserted into the original hubs, break under usage. Conversion plates are safe. No problems with them at all.

A wheel's bolt pattern can also be called its "Bolt Circle" or "Pitch Circle Diameter (PCD)". Bolt pattern is expressed as the number of lugs by the diameter of the imaginary circle formed by the center of the lugs. For example, 5 x 4.5 in., or 4 x 100mm.

How do you measure PCD? ›

How do you work out Pitch Circle Diameter? Measure the distance between two adjacent studs. Measure from the centre of the stud and mark down your measurement. This applies whether you have four, five, or six studs to measure between.

With the declared positive offset of 40, the wheel's mounting pad is located 40mm from the center line, towards wheel's front face, being 40mm from the center line position which is at 88.9mm.

The most popular cars with PCD 5x114,3 are: Honda Civic oraz Accord, Nissan Qashqai, Dacia Duster, Hyundai i30 and x35, Renault Megane III and Laguna III, Kia Cee'd, Sportage and Venga, Mitsubishi Lancer, Outlander and ASX, Toyota Auris and Avensis III, Citroen C-Crosser, Suzuki SX4, Fiat Sedici, Mazda 3.

It is important to know that 5×120 to 5×114.3 wheel adapters can only fit on 5×120 vehicle hub and adapt 5×114.3 wheels.

Wheels with a 5x115 bolt pattern can be found on a ton of great vehicles, including Buicks, Cadillacs, Chevrolets, GMs, Chryslers, Dodges, Pontiacs and more. Whether you're rocking that classic American muscle or a refined vehicle that boasts high-end luxury, you can amp up your ride's looks with 5x115 wheels.

Since the inception of the Toyota RAV4, the bolt pattern has always been 5x114.

A bolt circle of 5x114. 3 mm would indicate a 5 lug pattern on a circle with a diameter of 114.3mm (or 4.5").

PCD stands for Pitch Circle Diameter which basically means the diameter of an imaginary circle running through the centre of each bolt hole. The most common PCD values are 100mm and 114.3mm, the difference arising due to manufacturers using metric or imperial measurements (4.5 inches = 114.3mm).

What is the most popular lug pattern? ›

Found on passenger cars, SUVs and small pickups, rims with a five lug pattern are the most common.

The offset of a wheel is the distance from its hub mounting surface to the centerline of the wheel. The offset can be one of three types (measured in millimeters).* "The offset of a wheel is the distance from its hub mounting surface to the centerline of the wheel."

A: Yes, 6x5. 5 is a 6x139. 7 (it's metric vs. standard measurements).
