215 vs 255 Tires

215 vs 255 Tires

The main difference between these two tire sizes is the width of the tread. The 255 tire has 40mm wider tread than the 215 tire, which translates to improved grip on the road, better handling, and more stability when cornering or accelerating. In addition, having wider tires means more rubber on the ground, increasing traction while braking or driving in wet conditions.

215 vs 255 Table

This comparison table provides a quick and easy way to understand the differences between two tire sizes and to identify the distinctions between them with just a glance.

215 Tire Size 255 Tire Size

Recommended rim width range 6 to 7.5 inches Recommended rim width range 7 to 9.5 inches
Smaller than 255 tire size by 40 millimeters Larger than 215 tire size by 40 millimeters
Can replace 255 tire size (shared rim width overlap) Can replace 215 tire size (shared rim width overlap)

Fuel Economy
The size of your tires has a direct effect on your vehicle’s fuel economy. Smaller tires, such as those measuring 215, will generally lead to increased fuel efficiency due to their lighter weight and smaller surface area. On the other hand, larger tires, such as those measuring 255, will usually result in reduced fuel economy because they tend to be heavier and have a larger surface area.

When optimizing fuel economy, it is important to consider both tire size and inflation pressure. Tires with too much air pressure can create rolling resistance, which leads to decreased fuel efficiency. Conversely, under-inflated tires can cause excessive drag and sacrifice traction, reducing fuel efficiency. Therefore, it is important to maintain proper tire inflation pressure to maximize fuel savings.

Braking Performance
Regarding braking, tire sizes 215 and 255 have a distinct effect. The larger the tire size, the more grip and stability you get when stopping. Tire size 255 offers better grip and stability than tire size 215, making it easier for the driver to stop in a shorter distance. This is due to the increased contact patch of the larger tire, which provides more rubber on the road surface for better adhesion.

Ride Comfort
When comparing the tire sizes 215 and 255, there are distinct differences in ride comfort. Tires size 215 are generally considered to be better for overall ride comfort due to their smaller diameter.

This allows the tire to absorb bumps and imperfections in the road surface more efficiently. The smaller diameter also reduces the amount of weight put on each corner of the car, allowing for a smoother ride.

On the other hand, tires size 255 are designed to provide maximum grip with minimal rolling resistance. This makes them better suited for higher-speed driving situations such as highway driving or track use. As a result, these tires provide a firmer ride that can become uncomfortable over long distances.

Ground Clearance
To illustrate this point, consider a car with a 215 tire and one with a 255 tire. When driving on the same road, the car with the larger tire will have more clearance as its tires will not rub against the wheel wells or ride over bumps as easily. This additional clearance is especially beneficial when driving on roads with uneven surfaces due to potholes, debris, or other hazards.

Speedometer Readings
The size of the tires on a vehicle can directly impact the speedometer and odometer readings. Larger tires, such as 255, will cause the speedometer reading to be lower than the actual speed. This is because the larger tire circumference causes it to rotate slower per mile than a smaller tire. Therefore, if you are driving at 60 mph with 255 tires, your speedometer may only register 56 mph.

Similarly, with odometer readings, larger tires will cause it to measure fewer miles than you have actually driven. For example, if you drive 100 miles with 255 tires, your odometer may only read 93 miles due to the decreased rotations per mile from the larger tire circumference.

By understanding the effect of larger tire size on speed and distance measurements, drivers can adjust their expectations for tracking mileage and speeds when they decide to change the size of their tires.

How Much Wider Is A 255 Tire Than A 215?

The difference in width between a 255 tire and a 215 tire will depend on the specific tire model, but in general, a 255 tire will be approximately 40 millimeters wider than a 215 tire. To convert this to inches, 40 millimeters equals about 1.57 inches. Therefore, a 255 tire will be about 1.57 inches wider than a 215 tire.

How Much Taller Is A 255 Tire Than A 215?

The height of a tire is determined by its width, aspect ratio, and wheel diameter. Therefore, we need to know both tires’ aspect ratio and wheel diameter to determine how much taller a 255 tire is than a 215 tire.

For example, if we compare a 255/60R17 tire to a 215/60R17 tire, both with a 17-inch wheel diameter and the same aspect ratio of 60, the overall diameter of the 255 tires will be approximately 29.05 inches, while the overall diameter of the 215 tires will be about 27.16 inches. This means the 255 tire is about 1.89 inches taller than the 215 tires.

Are 215 And 255 Tires Interchangeable?

Each tire has a recommended rim width range that is typically provided by the tire manufacturer. This range indicates the minimum and maximum rim width sizes the tire can be safely mounted on. If the rim width falls within this range, the tire should be compatible with the rim.

The recommended rim width range for 215 tires is generally 6 to 7.5 inches, while for 255 tires, it’s typically 7.0 to 9.0 inches. As there is an overlap in the rim width range. Based on that, we can say that 215 And 255 Tires are Interchangeable.
