You may be an auto enthusiast, and you can have most of the relevant knowledge of how your vehicle works, but for most of the customers, it can be a tiring job for them to find what other wheels fit my car. However, if you want to buy custom or tricked out car rims online, you’ll need to be able to figure out the size for yourself.
Tires of any brand can be fit on the wheels of any other brand. The brand of the two products can go together well. Only the size has to be fit together to offer the tire to properly mounted on the wheel.
How To Know The Right Size Of Your Wheel
There are two easy ways to check what size wheels fit your vehicle. Check for the details from the sticker plate that should be located inside the driver side door, or look online for the vehicle specifications for your exact make and model for a better guide.
That should tell you the standard rim size. If you want to install larger wheels, as many drivers do these days, you need to do some measurements.
Measure the dimensions of your original wheels: First, measure the diameter and width of your wheels. You can choose a size that you want, but larger wheels can cause issues in the performance of your vehicle. Most people change the size of their wheels for the look or to downsize to save money: the price of the wheels (and tires) as its directly related to their size: the bigger, the more expensive.
Determine the offset of your original wheels: The offset can be determined by measuring between the centerline of the wheel and the mounting pad. The offset, when the mounting part of the wheel (where the bolts or nuts are installed) is located in the middle of the wheel is Zero Offset, more on its exterior side is Positive Offset or interior side is Negative Offset. Wheels with the wrong offset may rub on the body of the car or can interfere with the car’s brakes or suspension system.
Determine your bolt pattern: Lastly, the bolt pattern for the wheels plays its role in determining the size. The arrangement of the lug holes, represented by their number x the distance between them across the center of the wheel, for example, 5×114.3. Note down how many lugholes there are and what the diameter is between opposite holes. A bolt pattern of 4×100 means that the wheel takes four lug nuts and that the holes are 100mm
The bolt pattern is specific for every vehicle that can’t be changed. It has the same pattern on the wheel. Some wheels are universal and can be installed on various bolt patterns, and some of them are not.
Now: Find some wheels you’re interested in, and start plugging values into the comparison.
Some standard tire sizes for smaller passenger cars (yours may be different):
Armed with those baseline numbers, you can start comparing the overall diameter for the desired results. The tool will help you how much speedometer error you’ll experience if you’re adjusting tire size values
You also have a vehicle rated load index. This value determines how much weight each tire can hold. All mfg rate their cars at some load index value, for instance, 91T. IIRC. Some tire shops will refuse to mount tires that don’t match the load index rating of the car. So, these are the magic number for tires you’re looking for. That said, stick to stock size, and you won’t have problems with load index.
Lastly, keep the overall TIRE CIRCUMFERENCE within .5″ of the factory CIRCUMFERENCES.
Do not go just based on the sidewall measurements and calculated overall DIAMETER. Many tires of the same overall diameter have different circumferences.
Wider on tread width isn’t a smart decision. Wider is excellent for dry and clean pavements. It’s always bad for water, snow, and ice. Thinner tires will sink in more and give a better grip. You need to stick to the width, or you’ll swing too far and sink more than you want.
