175 vs 185 Tires

175 vs 185 tires

The main difference between 175 and 185 tires lies primarily in their width, with 175 tires measuring 6.89 inches (175 mm) across, while 185 tires stretch slightly wider at 7.28 inches (185 mm), a difference of 0.39 inches (10 mm).

Ride Comfort

Ride comfort sees a slight shift between these sizes. The narrower 175 tires may offer a smoother experience on well-paved roads, thanks to their smaller footprint and reduced tendency to pick up road irregularities.

In contrast, the 185 tires, with their broader base, can absorb impacts better, providing a more comfortable ride on less-than-ideal surfaces.

Ground Clearance

Ground clearance is not directly affected by the width of the tires but rather by their overall diameter.

However, assuming identical diameters, the primary concern shifts towards how these widths can influence your vehicle’s ability to clear obstacles, with wider tires potentially offering a marginally better approach to navigating rough terrains.

Gas Mileage

In the battle for fuel efficiency, the narrower 175 tires take the lead. Their smaller contact patch and lighter construction contribute to less rolling resistance, translating into better gas mileage.

The wider 185 tires, on the other hand, might slightly reduce fuel efficiency due to increased rolling resistance and weight.

Aesthetics Look

Aesthetically, the choice between 175 and 185 tires might depend on personal preference and the vehicle’s design. The 185 tires offer a beefier look, potentially enhancing the vehicle’s aggressive stance and appeal.

Conversely, 175 tires maintain a more traditional appearance, complementing the aerodynamics and sleek lines of a vehicle.

Handling & Stability

Handling and stability see a nuanced difference between the two sizes. The narrower 175 tires might provide sharper handling and quicker response on asphalt, benefiting urban drivers and those who prioritize agility.

The 185 tires, however, offer increased stability and traction, especially on uneven surfaces or during off-road adventures.

Noise & Vibration

Noise and vibration handling can vary, with 175 tires likely offering a quieter ride on smooth roads.

The 185 tires, especially if equipped with aggressive tread patterns, might generate more noise but could also better dampen vibrations thanks to their larger air volume and sidewall height.

Durability & Wear

Durability and wear patterns might not significantly differ between the two, but the 185 tires’ wider footprint could potentially lead to more even wear over time. Yet, this can also depend on driving habits and tire quality.

Adverse Performance

In adverse conditions such as snow or mud, the performance gap becomes apparent. The 175 tires might navigate through snow more effectively, cutting to the road below.

While the 185 tires could provide better traction in muddy conditions, thanks to their wider surface area.

What Does 175 Mean On A Tire?

The first number in the series typically represents the tire’s width in millimeters. For example, in the case of 175, this number refers to the width of the tire from sidewall to sidewall.

Therefore, a tire with a width of 175 millimeters is more comprehensive than a tire with a width of 155 millimeters.

How Much Wider Is A 185 Tire Than A 175?

The numbers in tire size, such as 175 and 185, represent the width of the tire in millimeters.

So, a 175 tire has a width of 175 millimeters, while a 185 tire has a width of 185 millimeters. Therefore, the difference in width between a 185 tire and a 175 tire is 10 millimeters.

How Much Taller Is A 185 Tire Than A 175?

The numbers 175 and 185 refer to the width of the tire in millimeters. While the height of the tire depends on other factors such as the aspect ratio, the load index, and the rim size.

Assuming both tires have the same aspect ratio and rim size, the difference in width between the two tires will only have a minimal effect on the overall diameter.

However, if we assume that both tires have the same aspect ratio of 65, the overall diameter of a 175/65r15 tire would be approximately 608.5 mm, while the overall diameter of a 185/65r15 tire would be approximately 621.5 mm. Therefore, the 185 tires would be around 0.51 inches or 13 mm taller than the 175 tires.
