In inches, the 275/60R20 tire size can be represented as 33.0" × 10.8" R20.
Is a 275-60R20 a 33-inch tire?
Yes, a 275/60R20 is considered a true 33-inch tire. While many tires in the 33-inch category actually measure slightly under or over, the 275/60R20 calculates out almost perfectly to the 33-inch mark with a 32.99" height, which essentially counts for 33.0’’.
Comparison of 275/60R20 With Similar Tire Sizes
Comparing 275/60R20 with other tire sizes, such as 285/60R20 and 265/60R20, helps highlight dimensional differences and clarifies whether alternative sizes are suitable replacements.
What Is The Difference Between 275/60R20 vs 285/60R20?
The main difference between 275/60R20 and 285/60R20 is the section width, with secondary differences in sidewall height, overall diameter, circumference, and radius. The 285/60R20 is 10 mm (≈ 0.39") wider, has a ≈ 6 mm (≈ 0.24") taller sidewall, and a ≈ 12 mm (≈ 0.47") larger overall diameter than the 275/60R20.
Although both tires share the same aspect ratio and rim diameter, the wider 285/60R20 results in a slightly larger overall tire.

Can I use 285/60R20 instead of 275/60R20?
Yes, using a 285/60R20 instead of a 275/60R20 is generally accepted. The overall diameter difference of approximately 1.4% remains within the commonly tolerated range and is unlikely to create clearance or suspension issues. However, the 285/60R20 is a physically large tire that sits at a "tipping point" for clearance on many 1/2-ton trucks. Many 275/60R20 tires are "P-Metric" (Standard Load). Also, many 285/60R20 tires are Load Range E (10-ply). This means the 285 will be significantly heavier and have a stiffer sidewall. You will notice a firmer, "truck-like" ride and may need to run higher tire pressures.
Even though 1.4% sounds small, the 285/60R20 is roughly 33.5 inches tall. On some stock 1/2-ton trucks (like a Chevy Silverado or GMC Sierra), this height and width can cause minor rubbing on the felt liner or the mud flaps during full-lock turns or while backing up. If you have a 3/4-ton truck (2500/F-250) or a 1/2-ton with a leveling kit, this is a perfect, "no-brainer" upgrade. If your truck is completely stock height, you may want to double-check fit for your specific year and model to ensure that the extra half-inch of height doesn't rub.

What Is The Difference Between 275/60R20 vs 265/60R20?
The main difference between 275/60R20 and 265/60R20 is the section width. Both tire sizes share the same aspect ratio and rim diameter, but the narrower 265/60R20 results in a slightly smaller overall tire.
Compared to the 275/60R20, the 265/60R20 is 10 mm (≈ 0.39") narrower, has a ≈ 6 mm (≈ 0.24") shorter sidewall, and a ≈ 12 mm (≈ 0.47") smaller overall diameter.

Can I use 265/60R20 instead of 275/60R20?
Yes, a 265/60R20 can be used instead of a 275/60R20 in most cases. The overall diameter difference is small (≈ 1.5%), meaning speedometer accuracy and ride height are only minimally affected. Since the 265/60R20 tire is both shorter and narrower than the 275/60R20, you will have absolutely zero rubbing issues. The narrower tread of the 265 tire can slightly reduce absolute grip in dry cornering or heavy braking. However, the narrower width is actually an advantage in deep snow or heavy rain, as it cuts through the surface rather than "hydroplaning" or "sledding" on top.
Many 265/60R20 tires are "Light Truck" (LT-metric) with a high Load Range (usually E/10-ply). If your original 275/60R20 tires were standard passenger-rated (P-metric), switching to an LT tire will make the truck ride significantly stiffer.Always ensure the Load Index of the new tire is equal to or higher than your vehicle's original requirements.
