175 vs 185 Tires

The most obvious distinction between 175 and 185 tires is their width. The 185 tires is about 10 mm wider than the 175 tires. The 175 tire measures 175 millimeters across the tread, whereas the 185 tire is 185 millimeters wide.

This difference of 10 millimeters may seem minimal, but it affects various aspects of your vehicle’s performance. A wider tire, such as the 185, provides a larger contact patch with the road, resulting in increased traction.

This improved contact can enhance your vehicle’s handling, especially during sharp turns or on slippery surfaces. Conversely, the 175 tire, being narrower, has less contact with the road, which often means reduced rolling resistance and potentially better fuel efficiency.

In addition to performance, aesthetic differences also play a role. The wider 185 tire may give your vehicle a more robust and sporty look, while the 175 tire maintains a more subtle, standard appearance. Your personal preference for aesthetics could therefore be a deciding factor in your choice.

On-Road Impact

The differences in width between 175 and 185 tires have several implications for on-road performance:

• Handling and Stability: The 185 tire generally provides improved handling, thanks to its wider contact patch. This greater contact area translates to better lateral grip, making the vehicle more stable during cornering or when driving at higher speeds. This is particularly beneficial for drivers who prioritize control and responsiveness.
• Fuel Efficiency: On the other hand, the 175 tire may be a better option for those who value fuel efficiency. The narrower profile creates less rolling resistance, meaning the engine doesn’t have to work as hard to keep the vehicle moving, resulting in improved fuel economy. This is especially noticeable during city driving, where frequent starts and stops can amplify the impact of rolling resistance.
• Ride Comfort: The 185 tire might offer a slightly more comfortable ride due to the larger contact patch, which can absorb more of the road’s imperfections. However, this can also lead to increased road noise, depending on the surface conditions. In contrast, 175 tires tend to be quieter but may transmit more vibrations from rough roads into the cabin.

Off-Road Impact

For those who occasionally take their vehicles off the beaten path, the choice between 175 and 185 tires can influence off-road capability:

• Traction on Loose Surfaces: The wider 185 tire provides enhanced traction on loose surfaces like sand, mud, or gravel, making it better suited for light off-road excursions. The larger contact area helps distribute the vehicle’s weight more effectively, reducing the likelihood of getting stuck in soft terrain.
• Precision and Maneuverability: In some off-road situations, however, a narrower tire like the 175 might be advantageous. The smaller width allows the tire to cut through loose surfaces more easily, providing better precision and making it easier to navigate through narrow trails or rocky terrain.

Speedometer Differences

Switching from 175 to 185 tires may also impact your vehicle’s speedometer and odometer accuracy. The overall diameter of the tire could change slightly, depending on the specific aspect ratio of each tire, which can affect how the speedometer calculates speed.

If the diameter of the 185 tire is larger, the speedometer may read slower than the actual speed, leading to inaccurate readings.

To maintain accurate speed and distance calculations, it may be necessary to recalibrate your vehicle’s speedometer after changing tire sizes. This ensures that your driving information remains reliable and consistent.

Benefits and Shortcomings

Benefits of 185 Tires:

• Increased Traction and Handling: The wider 185 tire offers a larger contact patch, resulting in enhanced traction and stability, especially during cornering and in wet conditions.
• Improved Aesthetic Appeal: Many drivers prefer the look of a wider tire, which can give the vehicle a sportier and more aggressive stance.

Drawbacks of 185 Tires:

• Reduced Fuel Efficiency: The increased rolling resistance of 185 tires can lead to slightly higher fuel consumption, which may be a concern for drivers focused on maximizing their vehicle’s efficiency.
• Potential Clearance Issues: Depending on your vehicle, the 185 tire might require more space in the wheel well, leading to potential clearance problems that could affect performance and safety.

Benefits of Staying with 175 Tires:

• Better Fuel Economy: The 175 tire has less rolling resistance, making it a more fuel-efficient choice, which is particularly important for daily commuting and long-distance driving.
• Easier Maneuverability: The narrower 175 tire may provide better maneuverability in tight city streets and parking spaces, making it ideal for urban drivers.

Drawbacks of 175 Tires:

• Less Traction: Compared to the 185 tire, the 175 has a smaller contact patch, which could lead to reduced traction, particularly on wet or slippery surfaces.
• Less Aggressive Look: For those who value aesthetics, 175 tires may not provide the same aggressive stance that wider tires offer, which could be a deciding factor for some drivers.

Difference Between 175 and 185 Tires

The main difference between 175 and 185 tires is the width. 185 tires are 10mm wider than 175 tires, which can significantly affect handling, stability, and overall vehicle performance.

Can I Use 175 Tires Instead of 185?

Yes, you can use 175 tires instead of 185 tires. The ideal rim width range for 175 tires (6.0-6.5 inches) overlaps with the minimum rim width for 185 tires (6.0 inches), ensuring compatibility.

However, keep in mind that narrower tires may not deliver optimal performance. It’s crucial to ensure that the new tires match the current aspect ratio and rim diameter. Any difference in overall diameter should not exceed 3% to avoid affecting speedometer accuracy and vehicle dynamics.

Can I Use 185 Tires Instead of 175?

Yes, you can use 185 tires instead of 175 tires. The ideal rim width range for 185 tires (6.0-6.5 inches) overlaps with the ideal range for 175 tires (6.0-6.5 inches), ensuring a proper fit.

Nevertheless, ensure that replacement tires have the same aspect ratio and rim diameter as your existing tires. Any variation in overall diameter should remain within 3% to prevent issues with speedometer readings and vehicle handling.

Can You Put 175 Tires on 185 Rims?

Yes, you can put 175 tires on rims designed for 185 tires. The ideal rim width range for 185 tires (6.0-6.5 inches) overlaps with the ideal range for 175 tires (6.0-6.5 inches), which ensures a suitable fitment.

Can You Put 185 Tires on 175 Rims?

It is possible to put 185 tires on rims designed for 175 tires, as the ideal rim width range for 175 tires (6.0-6.5 inches) overlaps with the minimum rim width for 185 tires (6.0 inches).

However, using wider tires on narrower rims may compromise handling and increase tire wear.

Our Observation

From our observations, the decision between 175 and 185 tires ultimately comes down to your driving preferences and priorities. If you’re looking for improved handling, traction, and a sportier look, the 185 tire is a great choice.

However, if fuel efficiency, maneuverability, and cost-effectiveness are more important to you, then sticking with 175 tires might be the best option.

Always consider the compatibility with your vehicle’s rims and available clearance before making a switch, and consult a professional if in doubt.
