Can You Change Tire Size on the Same Rim?

The performance of your vehicle can be affected by the tires that you use.

You can change the appearance of your vehicle by shifting to a giant wheel if you are not happy with the current tires of your car.

When the car turns, the flex on the smaller side of the tire is reduced. The stability of the side that is outside the tire is increased by a bigger tire.

If you move to a giant wheel, you will be able to find a greater variety of compatible tires, specifically high-performance models.

The weight also increases when the size of the wheels is increased. This causes the steering to be heavier and affects the fuel efficiency of the vehicle.

The car is more sluggish because the thinner side walls don’t provide as much cushion.

If the tires and wheels are the same internal dimensions, you can change the dimensions of your tires using the same rim.

If you don’t pay attention to the specifications from the manufacturer, you could end up with a tire that isn’t right for you.

Factors to Consider

Understanding the way the tire specifications function is the most important thing to do when changing the size of a tire.

If you know how to use a standard that all tire makers use, you will be able to locate tires that fit on your car wheels.

Internal Diameter of the Tire

The outside edges of the tires must be the same size as the rim if you want to change the size of your car tires.

The width of the tire doesn’t have to match the dimensions of the rim. The initial step in determining if you can use the same rim is choosing the tire’s size.

Browsing Tire Sizes

When looking at the tire dimensions, you have to keep in mind the three dimensions. millimeters, percentages, and inches are what it is.

The width of a car tire can be measured in millimeters or inches.

You can find the information about the size at the bottom of the tire if you know what you are looking for. It appears to be P250/55R17.

It’s a tire that is designed for passenger cars. Certain manufacturers don’t do this. Next is the size of the tire. In millimeters, it is expressed. The tire width is 250 millimeters.

The aspect ratio is the next. The word refers to how tall the sides are. Between the treads and the edges of the tire is the area that runs between them.

The ratio is not always proportional to the width. 55 percent of the 250 millimeters is equal to 137.5 millimeters.

The aspect ratio doesn’t affect how the tires fit on the rim, and the sidewalls may be flexed out or in slightly when you install the tires.

You can test the width of the tires with this. The following letter is often referred to as R. The tire is made using the letter as a reference.

Most car tires for passenger vehicles are radials. It’s going to be determined in inches. The tire’s inside diameter is 17 inches.

The final number should be the same if you are looking for new ones. The width and aspect ratio are two numbers that can be adjusted.

Considerations Before Changing the Tire Size

Bigger tires allow for more contact with the road and give better handling. If you did not go too far, it would be better.

There is a chance that you will damage your vehicle if you purchase too big tires. Changing tire size on the same rim will have significant factors to consider.

The Dimension of Wheel Well

There is not enough space for tires to turn. While traveling over rough terrain, tires are often juggled while turning.

You should be aware of the space in the wheel that your tires have inside. There is more room for larger tires than there is for larger-diameter tires.

Make sure that the tires don’t rub against the metallic in the wheel well or against the shock absorbers.

The Size of Tires

The bigger the tires, the higher the friction. There is increased road noise and lower gas mileage as a result. Changing the diameter of tires will affect the transmission.

The speedometer or odometer could be replaced. They were made to fit a specific tire diameter. When the wheels turn, the distance your car travels will be altered.

The difference could be as little as an inch. You can increase the speed by a couple of miles per hour if you add five percent of your aspect ratio.

You can use a car tire size calculator to find out how the new tires affect the vehicle speed. If there is a significant difference, you should adjust your speedometer.


There are many compelling reasons to change tire size on the same rim, not the least of which is the desire for better performance.

Better Aesthetics

A narrow tire is unattractive and inexpensive. The bigger the tires, the more attractive they seem.

If you look at the brand of the tire and the model, you will see that a giant tire covers the space between the wheel wells. This appears to be more sleek and elegant.

Improved Performance

Four areas are in contact with the ground due to the tires on the vehicle. This is the spot where the tire rubber touches the pavement.

When brakes are applied, the bigger the contact patches are, the better the tires will grip the pavement.

As you brake, accelerate or make sharp turns, your vehicle can keep a hold on its road if you have more contact patches.

The contact patches can be extended by increasing the dimensions of the tires or by increasing the aspect ratio. The contact patches can be made larger by choosing a bigger tire.

Better Handling

There are times when you can choose to go with smaller tires. Smaller tires are preferred if you install snow tires during the winter months.

In the case of heavy snow, smaller tires make it much easier to slice through the snow and slush. They are less vulnerable to hydroplaning on wet roads.

Wider Size Tires


It can be difficult to find the correct tire for your vehicle. Identifying the right tires for your car and driving style is a must.

The inner dimensions of the tires must be the same as the diameter of the rims. You can be flexible about the size of your tires and their aspect ratio.

Before purchasing tires for your vehicle, check the manufacturer’s recommendation for the brand and model of the tire.

Every tire has a set of wheels compatible with it. The tire is likely to work if your rims are in the range.
