The Difference Between 185 70R13 and 175 80R13 Tyres: What You Need to Know

The 185 70R13 has a lower profile, while the 175 80R13 has a higher profile.

185 70R13 Vs 175 80R13

When it comes to tire sizes, the differences between 185 70R13 and 175 80R13 might seem perplexing and difficult to understand. The numerical combinations after the size (R13) refer to the width of the tire on a 13-inch wheel diameter. Therefore, 185 70R13 stands for a tire 185 mm wide with a sidewall height of 70 and a 13-inch diameter rim. In contrast, 175 80R13 stands for a narrower tire at 175 mm in width but with an increased sidewall height at 80 mm.

Choosing between these two tire sizes can depend on personal preference or driving conditions like rain, snow, or other hazards. Wider tires typically provide better acceleration, cornering, and braking capabilities because they have larger contact patches with the ground and greater stability due to deeper tread design that allows more traction. On the other hand, narrower tires are lighter in weight, offer lower fuel efficiency due to reduced rolling resistance, and require less power from your vehicle to reach top speeds. Ultimately, selecting a tire size is based on what works best for you specifically based on your needs and preferences.

185 70R13 Vs 175 80R13


The size of a tire is determined by three measurements – the width, the aspect ratio and the wheel diameter. The 185 70R13 tire size means that the tire has a width of 185 mm, an aspect ratio of 70% and a wheel diameter of 13 inches. On the other hand, the 175 80R13 tire size has a width of 175 mm, an aspect ratio of 80% and a wheel diameter of 13 inches. The two tires have different widths and aspect ratios which will cause them to have different performance characteristics.


The 185 70R13 tire can offer better handling on dry roads due to its wider contact patch which creates more grip between the tire and the road surface. This also means that it will offer less rolling resistance when driving on smooth roads making it an ideal choice for highway driving. It also offers improved steering response when cornering as well as better traction in wet conditions. The 175 80R13 tire offers greater stability at higher speeds due to its taller sidewall which creates a larger contact patch with the road surface. This makes it ideal for off-road conditions as it can handle more bumps and uneven surfaces without compromising on control or traction.

Cost Comparison

The cost of tires can vary significantly depending on factors such as brand, quality, warranty, availability and type of vehicle they are intended for. Generally speaking, the 185 70R13 tires tend to be slightly more expensive than the 175 80R13 tires due to their wider width and shorter sidewall which increases their performance capabilities but also adds to their cost. However, it is important to note that this does not mean that all 185 70R13 tires are more expensive than all 175 80R13 tires as there are many other factors that can affect price such as brand and quality levels.

Features Comparison

When comparing features between different types of tires there are several key elements to consider such as ride comfortability, durability/longevity and noise levels. In terms of ride comfortability, both types offer a comfortable ride but due to its shorter sidewall height, the 185 70R13 provides better handling while still offering good cushioning over bumps and potholes in comparison to its taller 175 80R13 counterpart which provides greater stability but less cushioning over bumps or uneven surfaces. In terms of durability/longevity both types provide good wear resistance but due to its wider tread pattern with deeper grooves for improved water dispersion;the 185 70R13 tends to perform better when driving in wet conditions making it a more suitable option for year-round use in most climates although both types should last several years depending on how often they are used and how well they are maintained.

Road Types Suitability

When choosing between these two sizes it is important to consider what type of roads you will be driving on most often as each type offers different benefits depending on your needs: For highway driving then the shorter sidewall height offered by the 185 70r13 provides better handling at higher speeds while still offering good comfortability compared with its taller counterpart; however if you intend doing any off-road driving then you should opt for the taller 175 80r13 which provides greater stability over bumps or uneven surfaces while also providing improved traction in wet conditions due to its deeper grooves allowing for better water dispersion from beneath your vehicles tyres helping you stay safe no matter what terrain is thrown your way.

Traction & Safety Comparison

When comparing the traction and safety of 185 70R13 and 175 80R13 tires, performance on wet surfaces and resistance to hydroplaning are key factors. 185 70R13 tires provide better traction on wet surfaces due to their wider tread pattern, which helps disperse water more effectively. This improved wet performance allows the tire to grip the road better in rain and snow, providing better control and stability. In addition, the wider tread pattern of 185 70R13 tires also helps reduce hydroplaning by channeling water away from the tire more efficiently. The narrower 175 80R13 tires do not offer as much traction on wet surfaces as their wider counterparts, so they are not as adept at dispersing water or reducing hydroplaning.

Noise Level Comparison

The noise level comparison between 185 70R13 and 175 80R13 tires is also important when deciding which one is best for your vehicle. Generally speaking, 185 70R13 tires produce less cabin noise than their narrower 175 80R13 counterparts due to their larger surface area which helps absorb sound waves more effectively. In addition, these larger tires also provide less road noise due to their wider contact patch with the ground which helps reduce vibrations that can cause noise. On the other hand, 175 80R13 tires provide less cabin noise absorption due to their smaller surface area but still offer a decent amount of reduction in road noise compared to other narrow-width tires.

Brand Preference & Expert Opinion

When it comes to brand preference and expert opinion, there are a few key factors that come into play when deciding between 185 70R13 and 175 80R13 tires. When looking at brand preference, some brands may be more popular than others depending on certain factors such as price point or quality of materials used in production. Additionally, expert opinion can also be taken into account when selecting a tire size as certain experts may have different opinions on which size is best for various types of vehicles or driving conditions. Ultimately, it is up to the individual driver to decide which size tire they prefer based on their own personal preferences and needs.

Fuel Efficiency Comparison

Lastly, fuel efficiency comparisons between 185 70R13 and 175 80R13 tires should also be taken into consideration when selecting a tire size for your vehicle. Generally speaking, wider 185 70R13 tires tend to be more fuel efficient than their narrower 175 80R13 counterparts due to their lower rolling resistance which allows them to move with less effort from the engine thereby improving fuel economy overall. On the other hand, narrower 175 80R13 tires tend to offer slightly better handling characteristics but sacrifice some fuel efficiency in return due to their higher rolling resistance compared to wider tires.
