It is possible that a 165 tire could provide a more comfortable ride compared to a 185 tire. The narrower 165 tire has a smaller contact patch with the road, which can result in less road noise and potentially better performance on uneven surfaces.
However, other factors like tire construction, sidewall height, and vehicle suspension can also influence ride comfort. Considering all aspects before deciding which tire size will provide the most comfortable ride for your specific vehicle and driving conditions is essential.
Wet & Snow Traction
In adverse weather conditions, 165 tires often provide superior traction due to their higher pressure per square inch (PSI) rating. This increased PSI enables the narrower tire to more effectively penetrate snow, slush, and rain compared to a wider 185 tire.
Although a larger contact patch can enhance dry traction, it can also hinder the tire’s ability to slice through snow and make contact with the ground beneath.
The 185 tires generally provide better traction on dry roads compared to the 165 tires. The primary reason for this is the wider contact patch of 185 tires, which allows more rubber to grip the road surface.
This enhanced grip improves stability and handling, particularly during cornering and acceleration. However, it’s essential to consider other factors like fuel efficiency and wet weather performance when choosing between 165 and 185 tire sizes for your vehicle.
Aesthetically, many people find that 185 tires appear more appealing than 165 tires due to their wider profile. Wider tires can give a vehicle a sportier and more aggressive look, which is often preferred by car enthusiasts.
However, personal preferences vary, and the ideal tire size for your vehicle will depend on your specific taste and the overall appearance you desire.
Regarding fuel economy, a tire’s size can make a big difference. The general rule of thumb is that the larger the tire, the more rolling resistance it will have, resulting in lower fuel economy. It is important to note that other factors such as vehicle weight and engine output also affect fuel economy.
If a vehicle has higher power output or heavier weight, then it may achieve a different level of fuel efficiency when using a larger tire size. It is always best to consult with an expert before making any changes to your vehicle’s tires to ensure you are achieving optimal performance and efficiency.
What Does 165 Mean On A Tire?
The number “165” on a tire refers to the tire’s width in millimeters. Precisely, it measures the tire’s section width, which is the distance between the outermost points on the tire’s sidewalls when it is mounted on a standard rim and inflated to the recommended pressure.
For example, a tire with the marking “165/65R14” indicates a width of 165 millimeters, an aspect ratio of 65, and is designed to fit on a 14-inch rim. The aspect ratio, represented by the second number in the marking, is the ratio of the tire’s height to its width.
How Much Wider Is A 165 Tire Than A 185?
The 185 tires are wider than the 165 tires. In fact, a 185 tire is approximately 20 millimeters wider than a 165 tire. To be more specific, a 165 tire typically has a width of 165 millimeters. In comparison, a 185 tire typically has a width of 185 millimeters. Keep in mind that the actual width can vary slightly depending on the specific tire model and brand.
How Much Taller Is A 185 Tire Than A 165?
The overall diameter of a tire is determined by the combination of its width, aspect ratio, and rim diameter. The aspect ratio is the ratio of the tire’s height to its width.
Assuming that both the 165 and 185 tires have the same aspect ratio and rim diameter, and only the width of the tires is different, the 185 tires would be approximately 26 millimeters taller than the 165 tires.
To provide a specific example, let’s say that both the 165 and 185 tires have an aspect ratio of 65 and a rim diameter of 15 inches. In this case, the overall diameter of the 165 tires would be approximately 595.5 millimeters. In contrast, the overall diameter of the 185 tires would be approximately 621.5 millimeters. Therefore, the 185 tires would be approximately 26 millimeters taller than the 165 tires.
Can I Replace 185 Tires With 165?
It is important to consider the manufacturer’s tire size, aspect ratio, and rim width recommendations. These recommendations are based on the tire’s design and intended use and help ensure proper performance and safety.
In general, it is possible to replace a 165 tire with a 185 tire as long as the rim width is within the recommended range for the 165 tires. The recommended rim width range for 165 tire sizes is 4.5 to 5.5 inches. On the other hand, the recommended range for the 185 tires is 5 to 6 inches.
If the rim width of your vehicle falls within the recommended range for the 185 tires you are considering, you should be able to use it as a replacement for the 165 tires. As we can see, there is an overlapping in the rim width range. That means we can Replace 185 Tires With 165 tire sizes.
In conclusion, our observations have led us to the consensus that switching from a 165-size tire to a 185-size tire is beneficial in certain circumstances. However, it is important to take into consideration the disadvantages of both sizes before making such a switch.
The increased height of the 185-size tire may provide better performance on dry roads and wet surfaces, but it also comes with an increase in rolling resistance and drag that can negatively impact fuel economy.
Furthermore, the wider width of the 185-size tire may be beneficial for improved stability on curves and straights. Still, it can also lead to increased wear on suspension components due to additional loading forces.
