Therefore, a 275 60R20 tire is a large SUV or pickup truck tire with 10.8 inches section width, 20.00 inches rim diameter, 103.6 inches circumference, and 33 inches overall diameter.

This tire is further designed to deliver 612 revolutions per mile, and they are mounted on 7.5 inches – 9.5 inches wide wheels. The 275 60R20 tires are also manufactured for use in larger SUVs and pickup trucks like GMC Yukon, Toyota Tundra, Ford F–150, Dodge RAM 1500, etc.

275 55R20 Vs 275 60R20 Differences

Although the 275 60R20 features “60” on its tag name, it is simply the latest variation of 275 55R20 tires. However, there are some slight differences you can easily spot from their designs as you consider their measurements.

If you’re contemplating, “What’s the difference between 275 55R20 and 275 65R20?” The following analysis on the comparison table below attempts to bring the design features of both 275 55R20 and 275 60R20 tires to bear.

Although both tires have a similar section width, there are other features that clearly distinguish them. Let’s briefly analyze three (3) of them.

Overall Diameter

The overall diameter of a vehicle’s tire is the outer diameter. It is measured by taking note of the two sidewalls – the upper sidewall above the wheel and the lower sidewall (touching the ground) below the wheel and the wheel’s diameter aside from the tire itself.

Typically, the 275 60R20 diameter is 33 inches as against the 31.9 inches overall diameter of 275 55R20. So, it is obvious that 275 60R20 is taller than 275 55R20.

Aspect ratio

A vehicle’s tire aspect ratio depicts the height of its cross-section in relation to the width. Although both tires have a similar section width of 10.8 inches; however, 275 60R20 features an aspect ratio of 60%.

Conversely, 275 55R20 comes with an aspect ratio of 55%. That’s clearly a difference of 5%. So, even though both tires have the same width, you need to take cognizance of the aspect ratio before considering one for the replacement of the other.

Wheel Circumference

The circumference indicates the distance around the outer region of the vehicle’s wheel. This also includes the tire’s additional width. The circumference enables a vehicle to maintain balance and brake as fast as possible.

Typically, a larger circumference means more balance and swifter braking. So, since the 275 60R20 has 103.6 inches circumference as against the 100.2 inches of the 275 55R20, it will most likely provide a better balance and braking engagement. This is clearly beyond the 27555R20 ride quality.
