How Do 55 and 60 Tires Differ? Everything You Need to Know

Comparing a 55-series tire versus a 60-series tire, it’s crucial to understand the importance of the aspect ratio and its effects on vehicle performance and comfort.

What Does the Number Mean?

The number 55 or 60 in the tire size is the aspect ratio. It measures the height of the tire’s sidewall as a percentage of its width.

For example,

• A tire with an aspect ratio of 55 – the height is 55% of the tire’s width.
• A 60 aspect ratio – the tire’s sidewall is 60% of its width.

I have reviewed both and given a detailed comparison – 55 Vs 60 Tire Comparison. I hope it will help you choose the right one that suits your car.

1. Ride Comfort

When the tire size is changed to a larger aspect ratio 55 series to 60 series, the flexibility between the tire and rim is greater, which gives you a smoother ride.

A 60 tire has a taller sidewall and provides a smoother and more comfortable ride. A 55 tire has a shorter sidewall, which makes the ride feel firmer.

Tire ratio	Sidewall	Ride comfort
55-Series Tire	shorter	sportier look less cushioning less comfortable ride
60-Series Tire	taller	minimized vibrations greater cushioning more comfortable ride

2. Handling and Stability

The 55 tire, with its shorter sidewall, improves how your car handles, when cornering or taking sharp turns. A shorter sidewall reduces the tire’s flex, making it more stable at high speeds. For drivers who prefer sharp handling, the 55 tire would be a better choice.

A 60 tire, on the other hand, offers less handling precision because its taller sidewall has more flex, which can make it feel less stable in fast turns.

55-Series Tire >> 60-Series Tire

Although 60-series tires offer a more comfortable ride, additional flex gets in during cornering. It can affect the vehicle’s precision and stability.

Comparatively, flex is diminished in 55-series tire with reduced sidewall flex, hence helps to maintain consistent grip and better handling.

3. Speed and Performance

Performance is another area where 55 and 60 tires differ.

A 55 tire typically offers better performance at high speeds, as it provides more stability due to its shorter sidewall. This makes it a good option for sports cars or drivers who like to drive at higher speeds.

A 60 tire, while offering a more comfortable ride, is not as focused on speed. It’s better suited for drivers who prioritize comfort over performance.

4. Fuel Efficiency

A 55 tire is more fuel-efficient than a 60 tire because it has less rolling resistance. Since 55 tires have a shorter sidewall, they are often lighter and need less energy to move, saving on fuel.

A 60 tire, with its taller sidewall, has more rolling resistance, which may lower fuel efficiency a little.

60-series tires have higher rolling resistance, which increases the fuel consumption compared to 55-series tires.

5. Speedometer Accuracy

The Speedometer Accuracy is affected by its aspect ratio. A tire with a higher aspect ratio has a larger diameter compared to a lower aspect ratio tire.

For instance, a 60-series tire covers more distance per revolution, which may cause the speedometer to under-report speed while a 55-series tire leads to an overestimation of speed.

6. Off-Road Capabilities

A 60 tire might serve you better if you drive on gravel, dirt roads, or any surface that isn’t smooth. The extra height of the sidewall makes it more durable for off-road driving because it can absorb the impact of rocks and bumps more effectively.

A 55 tire is less ideal for off-road conditions because its shorter sidewall may not handle rough terrain as well.

7. Cost

The price difference between 55 and 60 tires depends on the brand, type, and features of the tire. Generally, 55-series tires are more costly due to their performance features and the use of specialized materials than 60-series tires.

You can check the price of it on Amazon. (55-Tire & 60-Tire)

FAQ

1. What do 55 and 60 mean on tires?

The numbers 55 and 60 refer to the tire’s aspect ratio, which is the height of the sidewall compared to the width. A 55 tire has a lower profile, meaning the sidewall height is 55% of the tire width, while a 60 tire has a higher sidewall at 60% of the tire width.

2. Do 55 tires handle better than 60 tires?

Yes, generally 55 tires offer better handling due to their lower sidewall, which provides less flex during cornering. However, 60 tires offer a smoother ride because of the higher sidewall, which absorbs bumps better.

3. Will 55 and 60 tires affect fuel efficiency?

Tires with a lower aspect ratio, like 55, can slightly improve fuel efficiency because they are often lighter and create less rolling resistance. However, the difference is usually minimal between 55 and 60 tires.

4. Can I replace 55 tires with 60 tires?

You can replace 55 tires with 60 tires if they fit your vehicle’s specifications, but it will affect the ride quality and handling. Always check your car manufacturer’s recommendations before switching tire sizes.

5. Which tire size provides a more comfortable ride: 55 or 60?

60 tires typically provide a more comfortable ride due to their higher sidewall, which helps cushion impacts from road irregularities better than 55 tires.
