So, how much do you know about customizing wheels? Is it true that the bigger the better?

Let now clarify the issue of “can i replace 16 inch wheels with 18 inch?

Can i replace 16 inch wheels with 18 inch?

The fact that you have two tires of varying sizes on the front (or back) of your car is a concern. Having two tires of different sizes mounted on the same axle is not a smart idea in most cases. Larger tires on the rear axle of a vehicle can be installed for a variety of reasons, including improved handling, aesthetics, and other factors.

When it comes to replacing the original wheels and tires on an automobile, the general rule of thumb is that you can go up or down one inch in any direction. As an example, switching from an 18-inch wheel to a 16- or 15-inch wheel is unlikely to be successful since the wheel will not fit over the brakes.

From 16 inch wheels to 18 inch wheels what will happen???

In fact, even if the tire profile is lower, the ride quality can be improved by using lighter weight wheels and tires. The reason for this is because with less weight, the suspension has an easier time doing its job. On my S4, I updated to 19-inch Volks (forged) rims, which, when combined with the tires, resulted in a weight savings of 10 pounds per corner when compared to the 18-inch OEM rims. The riding became much smoother (as did the acceleration and handling).

Is it true that moving from 16″ wheels to 18″ wheels results in a 2″ increase in driving position in the same car?

No, it would only increase it by one inch at the most. The diameter, not the radius, is 18 inches.
In practice, it is possible that it has no effect on the ride height at all. Tires for 18-inch wheels have a reduced profile, which allows the overall radius to remain the same. Unless the wheels are of exceptionally good quality, upgrading from 16-inch to 18-inch wheels will almost always result in lower performance due to the increase in unsprung weight. Assuming that both wheels are equipped with tires that have the same sidewall height, there would be a 1′′ difference in ride height between the two wheels.

 Precautions for changing 16 inch wheels to 18 inch wheels

First and foremost, it is not permitted in China, according to policy, to replace wheels with sizes that are not original to the vehicle.

The Road Traffic Safety Law states unequivocally that no unit or individual may build a motor vehicle or change the registered structure, structure, or attributes of a motor vehicle without the prior written consent of the vehicle’s manufacturer. Unauthorized modification of a motor vehicle’s chassis, engine, suspension, transmission system, direction system, tires and wheels, lights, body color painting, and appearance structure is prohibited without the permission of the traffic management department of public security. unauthorized modification
However, while the present New Deal permits the replacement of a wheel hub, the wheel type cannot be changed, and the wheel size restrictions are not permitted to be altered. As a result, 16-inch wheels that have been modified to accommodate 18-inch wheels are not permitted to be filed with the vehicle management office. The annual inspection will not pass after the change has been completed.

Precautions for changing 16 inch wheels to 18 inch wheels
Second, the larger the wheel hub, the more likely it is that the bearing will be damaged, and the larger the wheel hub, the thinner the tire will be, the more noticeable the feeling on the road, and the more likely it is that the driving comfort will be compromised. After all, the wheel hub is a critical component of the automobile. Changing a large-size wheel hub in a haphazard manner will result in severe consequences, including vehicle accidents.

When it comes to wheel modification, you must exercise caution. Do not follow the opinions of others without questioning them. If the automobile wheels are in good condition and have not been damaged, it is advisable not to make any alterations to them.

Disadvantages associated with this:

1. When driving, the odometer will be out of tolerance, which means that the speed displayed on the odometer will be inconsistent with the actual speed of the vehicle.

2. When crossing a bumpy road, the tires will make contact with the body. (Replace the flat tires.)

3. When replacing tires, it is also necessary to replace the shock absorbers and odometer sensors.

What Difference Does Wheel Size Make?

Greater stage presence and a more forceful attitude are achieved by the use of larger wheels, which is why automakers use king-size rims on concept vehicles. They have a cool appearance.

Whether you choose a larger-diameter wheel as an option on a new vehicle or as aftermarket wheels for a vehicle you already own, there are advantages to plus-sizing as well as disadvantages. When you increase the diameter of your wheels (for example, from 17 to 18 inches), you must purchase new tires to match. When such tires go over bumps and potholes, they require a lower profile (or sidewall height) in order to retain appropriate clearance, which causes the suspension to fully compress and rebound. If the diameter of the wheel grows by one inch, the height of the tire should reduce by the same amount to compensate, in order to maintain the overall diameter at the same level.

Using the above example, if your vehicle’s stock tires are 215/65R17 and you purchase 18-inch wheels, the appropriate tire size for the larger rims may be 225/55R18, with the differences being the larger-diameter wheel size, wider tread (225 millimeters instead of 215) and lower profile (55 instead of 65). As a result, the height of the sidewall is equal to 55 percent of the width of the tread.

If you upgrade to larger wheels without taking sidewall height into consideration, you not only run the risk of causing damage to the suspension, wheels, and tires, but you also run the risk of receiving incorrect speedometer readings because the wheels are turning at a different speed than they were previously. By matching lower-profile tire sizes to larger-diameter wheel sizes, the readings on the speedometer and odometer should only be slightly altered, if they change at all. As a result of the larger wheels and lower profile tires (and the resulting shorter sidewalls), they are stiffer and there is less air and rubber cushion than in the past, increasing the likelihood that hitting a huge pothole may cause damage to the tire, wheel, or both.

Even though larger diameter wheels and tires should provide better handling and high-speed performance, lower-profile tires tend to provide a harder ride and may be noisier than smaller, conventional tires.

Some of the potential performance advantages of larger tires and wheels may be outweighed by the greater weight of the larger tires and wheels. An 18-inch tire, for example, will almost certainly weigh at least a couple of pounds more than a 16- or 17-inch tire of the same size and tread pattern. That could also be true for a wheel of a bigger diameter. Given that steel wheels are heavier than aluminum alloy wheels, the latter’s performance is improved by reducing the unsprung weight of the wheel. However, replacing a regular 17-inch alloy wheel with an 18- or 19-inch alloy rim will increase the weight of the vehicle – unless the alloy wheel is an expensive, lightweight one.

Larger wheels come at a higher price. The wheels and tires get more expensive as the size of the vehicle increases. Purchasing wider wheels as part of an option package on a new car or having them as standard equipment on a higher trim level may not result in a significant increase in the vehicle’s initial cost. However, when it comes to repairing a damaged wheel or tire (or just the replacement tires as the tread wears away), the additional expense might be significant.

According to, when they analyzed the replacement costs of different wheels and tires, a basic 16-inch steel wheel for a Toyota Camry cost $172 to repair at a Toyota shop. A set of 17-inch alloy wheels for a Toyota Camry XLE, on the other hand, cost $379. One dealer told us a price of $371 for an 18-inch alloy wheel on a Chevrolet Traverse, while another quoted us a price of $569 for an extra 20-inch wheel.

Your Guide To Upgrading Wheels and Tires

You car’s four little contact patches that grip the road are the most crucial pieces of real estate it has, and they are called tires. Those few square inches of rubber have a significant impact on almost everything. Tires are responsible for harnessing the power of an engine, allowing the brakes to do their jobs, and determining how well a car will go around a turn, regardless of whether the automobile is pulling into a parking slot or screaming into a high-speed sweeper.

Your Guide To Upgrading Wheels and Tires

Yes, tires bear a tremendous amount of weight. That thin, round, and black doughnut is actually a sophisticated assemblage of cables, rubber, and polymers, all of which have been molded into a highly designed profile. It’s then installed on a wheel and, of course, inflated with air to give it shape and definition, before being rolled away. Vehicle, tire, and wheel manufacturers collaborated to develop the optimal combination of grip, road feel, ride comfort, noise control, and tire wear for your vehicle, tires, and wheels.

FQA can i replace 16 inch wheels with 18 inch

Can I put 18 rims instead of 16?

An 18-inch tire, for example, will almost certainly weigh at least a couple of pounds more than a 16- or 17-inch tire of the same size and tread pattern. Steel wheels often weigh more than aluminum alloy wheels, which is the exception. The addition of an 18- or 19-inch alloy rim to a regular 17-inch alloy wheel will increase the weight of the vehicle (With exceptions)

What is the advantage of 18 inch wheels?

The Advantages of 18-Inch Wheels and Tires

Given the greater sidewall of 18-inch tires compared to those with a narrower sidewall, they are generally considered more flexible. When you drive over bumps and potholes, your tires work as shock absorbers and can provide a higher amount of cushioning.

Can you change the size of wheels on a car?

When it comes to replacing the original wheels and tires on an automobile, the general rule of thumb is that you can go up or down one inch in any direction. Consider the following example: if your car is now equipped with 17-inch wheels, you can lower the size to 16 inches by using smaller wheels.

Can I replace 16 inch wheels with 19 inch?

The same is true for most vehicles; we can usually go even lower in profile with a Plus 2 (for example, going from 16- to 18-inch wheels) or Plus 3 (16- to 19-inch wheels) upgrade without encountering any issues.


As a general rule, it is not recommended to reinstall wheels that have an excessively large span. Change the wheels from 16-inch to 18-inch without any modifications. It is vital to choose tires with a lower aspect ratio in order to retain the circumference of the tire as long as possible; nevertheless, this will diminish the comfort of the car. In addition, because the large wheel hub will increase tire noise and fuel consumption, and even worse, it will wear out the car, I recommend that you change the wheel hub to meet your specific demands while increasing the size in a reasonable manner. It is not possible to directly change 18-inch wheels with this method.
