The aspect ratio is a critical sizing factor in tire fitment and should be evaluated along with wheel diameter to obtain the optimum tire and wheel combination. Let’s discuss tire aspect ratio 60 vs 55.
There are so many sizes and widths available that it can seem challenging to narrow down the choices. However, if you want the giant tires available, fear not! Any size 55 or 60 tire will have adequate tread on the road surface to fit any driver.
People’s main problem with this selection is usually what they think is attractive rather than anything else. So don’t waste time determining if the size is wider-just choosing the one that best suits your requirements and preferences!
Your tires are an integral part of your vehicle and play a critical role in keeping you safe on the road. There are numerous factors to consider when shopping for new tires, but one essential factor is width.
Since different tire sizes have varying dimensions, there is no one-size-fits-all solution for your vehicle. Thus, we will discuss some of the distinctions between size 55 and 60 tires and how they can help you choose the right one for you.
Tire Aspect Ratio 60 vs. 55 Features
Features | Description | 55 | 60 |
Comprehensiveness | The numbers 55 and 60 refer to the size of the tire. The first number indicates the width in millimeters, while the second is the height, or aspect ratio, which shows how taller the object is than the width. | A 55-series tire will be more comprehensive than a 60-series tire. | The 60 perform better in sedan models than trucks |
Wide | However, they are called the 55 series because their aspect ratio (ratio of the section height to section width) is less than 60. This means they cannot be used on vehicles manufactured after World War II when the standard size became popular. | When the width of the 55 is increased, the ratio of revolutions per kilometer decreases (as long as it remains at 15% or less). | When the width of the 60 is increased, make the revolutions per mile. |
Stability | Additional aspects to consider are sidewall height, which is shorter on 55-series tires than on 60-series tires. Sidewalls are critical in determining the tire’s contact patch and grip. | The shorter sidewall height of 55-series tires results in a larger contact patch, resulting in more excellent grip and stability. | The sidewalls of 55-series tires are somewhat shorter than those of 60-series tires. |
A high and wide combination | This value indicates the balance of a tire’s sidewall height to its width and height. | An aspect ratio of 55 indicates that there is one 459 mm (117.5 inches) segment of width for every 100 mm or 3-inch piece of height, which equates to approximately 1:2, as stated above in the “1: 2 male/female ratio” | A 60-inch tire should be between 8.5 and 11 inches wide. For a 60-inch tire, the most common wheel and tire size range are 8.5′′–11′′′. |
Which tire size is more comprehensive, 55 or 60?

When evaluating the tires available for your car, you can determine which is wider by comparing the width of each tire to the width of your choice. There is no need to reach heights because both types will be approximately the same size. You will undoubtedly notice that tires for smaller vehicles, such as compact sedans or hatchbacks, have a smaller aspect ratio than those for SUVs and larger trucks.
Are 60 Tires Wider Than 55?
When you think about automobile tires, the first image that generally springs to mind is those enormous, tall ones with numerous sidewalls. However, there is another type: the shorter ones! These “short ones” come in various sizes, like the regular 275. The width changes when moving from the 60 to the 55 series.
How Wide Are 55 Inch Tires?
It is critical to understand all the ratio elements when calculating the height and width of your tire.
- The 60 aspect ratio indicates that the section height and width are about 1:1.5, making it a relatively small tire compared to 55s (about 1:1.7).
How wide is a 60-inch tire?
Your 315/60R15 tires have a diameter of 29.9 inches, a section width of 12 inches, and wheel sizes ranging from 15 to 20 inches for your truck, SUV, or van!
This equates to approximately 675 rotations per mile for each tire, which helps keep you safe on the road when circumnavigating the city.
What Does 55 Mean On Tires?
55 signifies the aspect ratio of the tire. A tire with an overall diameter of 25 inches and a section height of 5 inches, for example, has an aspect ratio of 55 (25′′ x 5 inches).
55-series tires have a sidewall height equal to 55% of their width. The sidewall heights of 60-series tires are equal to or greater than their section widths.
Bottom line
If you’re looking for new tires, it cannot be obvious to determine which size will be best for your car. Compared to 60-series tires, 55-series tires have somewhat shorter sidewalls. This means that the lower sidewall height of 55-series tires translates into a larger contact patch, which translates into more grip and stability. A 60-inch tire should be between 8.5 and 11 inches wide.
Your 315/60R15 tires provide a 29.9-inch diameter, a 12-to 4-inch section width, also a wheel diameter of 15 inches or more for your truck, SUV, or van. Each tire spins about 675 times per mile, which helps keep you safe on the road.
