How do I know if alloy wheels will fit my car?

How do I know if alloy wheels will fit my car?

There are 10 aspects that are critical for your choice of alloy wheel to fit properly:

• The Wheel PCD (Pitch Circle Diameter / Stud Pattern)
• The Front and Rear Wheel Offset (ET)
• The Wheel Diameter.
• The Front and Rear Wheel Width/s.
• The Front and Rear Tyre Size.
• The Wheel Load Capabilities.
• The Tyre Load Index.
• The Centre Bore.

Can you put any size alloys on a car?

Every vehicle has a compatible rim width range (not a fixed width). For example: Audi A3 2002 has an offset range between 6J and 8.5J, as long as the rim width is within that range, the alloy wheels will be fully compatible. Every vehicle has a compatible offset range (not a fixed offset).

How do you measure if a wheel will fit?

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.

Are rim sizes interchangeable?

It depends. Wheels and tires are not interchangeable words. Tires are a part of the wheel setup. For instance, your vehicle has a set size of rims, but you can buy different sizes of tires to fit those rims, as long as the middle of the tires is the correct size.

How do I know my alloy wheel size?

Every alloy wheel should have the size on the tyre; you can find this on the outside or sometimes it is stamped on the inside of the alloys or the back of the spokes. Contacting a specialist is a good idea if you are still unsure about what the diameter and width of your alloys is.

Can you put wider tires on the same rim?

As a general rule of thumb, it’s safe to fit a tire up to 20 millimeters wider than stock on the original rim. The actual width of the tire will vary depending on the width of the rim: The tire will expand 5 millimeters for every half inch (12.5 millimeters) increase in rim width.

How do you read rim markings?

The wheels width is usually written beside the flange shape marking – e.g: 7j, 7.5j, 8.0j. The width of the wheel is basically the area shown on the photo above and it is measured in inches. In other words, the bigger the number, the “thicker” your wheels are.

How do you find out what alloys I have?

Look for a logo or the name of a wheel manufacturer imprinted on the back of the wheel. There might also be the size of the wheel, the offset, and the date it was manufactured, depending on the company that made it.

What is the J in wheel size?

The letter “J” means a tyre bead profile. This is the marking used to define the wheel collar profile you should never ignore. Wheel collars and tyres must be compatible.

How do I find my wheel offset?

Subtract the smaller number from the larger number. That gives you the offset of the wheel. If the centerline number is smaller than the hub measurement, offset is positive.

Are 16 inch wheels better than 17 inch?

AAA – Yes, wheel size has a big impact on ride comfort. The smaller 16-inch wheels come with tyres that have larger sidewalls that act as cushions against sharp edges on the roads, like ruts and potholes. While 17-inch tyres look much better, the shorter sidewalls aren’t as good in filtering out road shocks.

Are 17 inch wheels good?

Subjectively, both the 17-inch and 18-inch wheels and tires were in the sweet spot of grip, braking performance, ride comfort, and steering feel. Moving from 17-inchers to 18s barely degrades ride quality, and the additional grip is welcome.

Does a wider tire give a better ride?

As a general rule, bigger wheels result in a rougher ride. Switching to a smaller wheel and a thicker tire can give you a smoother ride without any major modifications to your car. If you’re looking for a bigger wheel which can provide better handling, you can go up to an 18-in wheel.

How do you know if a rim is matching?

Compare the wheel to those sold at online wheel and tire companies, such as Tire Rack, if there are no markings on the wheel. Compare the wheel to photos of other wheels until you have a match. Use an automotive forum to ask what kind of wheel you have.

Will wheels clear my brakes?

If your wheel is going to fit, it has to clear your calipers too, and it turns out that this is a lot harder to calculate for. If you are staying with stock calipers, again, this will be easier because if you can find any site that has test fit wheels, then you know that they will clear.
