275/70R17 Tire Size

All You Need to Know About 275/70R17 Tires

275/70R17 tires are 275 mm wide, with a 70% aspect ratio and a 17-inch wheel diameter, producing a 32.2-inch overall diameter and a 7.6-inch sidewall height. The rim width range for 275/70R17 tires is 7.0–9.0", with a measuring width of 8.0". 

The 275/70R17 size sits between the common 265/70R17 and 285/70R17 truck sizes, and is typically chosen by drivers who want a slightly taller and wider setup without moving all the way into a full 33-inch-class off-road fitment. 

On many vehicles, 275/70R17 tire size is an upgrade size rather than a factory baseline, so wheel width, offset, and clearance matter more here than they do with smaller stock-equivalent sizes, such as 265/70R17.

275/70R17 Common Vehicle Fitment

275/70R17 is more often an upgrade size than a widespread OEM baseline. It is commonly run on leveled or lightly modified Tacoma, 4Runner, F-150, and Silverado builds where the driver wants more ground clearance and a wider section width without stepping to the heavier 285 class. On most of these platforms, running 275/70R17 requires verifying wheel width, offset, and arch clearance, as it is not a straight stock swap.

275/70R17 Dimensions in Inches

The 275/70R17 tire size is ≈10.83 inches wide, ≈32.16 inches tall overall, and has a sidewall height of ≈7.58 inches. 

At 32.2 inches, 275/70R17 sits clearly above the 31-inch class but below the true 33-inch group, which is why it often works as a middle step for drivers who want more tire without going to the visual and clearance demands of 285/70R17.

Comparison of 275/70R17 With Similar Tire Sizes

275/70R17 sits directly between 265/70R17 and 285/70R17 in both section width and overall diameter. Compared to 265/70R17, it adds a modest amount of height and width while staying within the ±3% range. Compared to 285/70R17, it remains slightly narrower and shorter, which is often enough to reduce clearance pressure on stock or near-stock trucks.

Difference Between 275/70R17 and 265/70R17 Tire Sizes

The 275/70R17 is moderately wider and slightly taller than the 265/70R17:

• Width: 275/70R17 is 10 mm wider than 265/70R17
• Overall diameter: 275/70R17 is ≈0.55 inches (≈1.7%) larger than 265/70R17

The overall diameter change stays within the ±3% rule, so 275/70R17 and 265/70R17 are generally considered interchangeable from a diameter standpoint. The main thing that still needs verification is added width, especially on narrower wheels or tighter front-end clearances.

Difference Between 275/70R17 and 285/70R17 Tire Sizes

The 285/70R17 is one step larger than the 275/70R17 in both width and overall height:

• Width: 285/70R17 is 10 mm wider than 275/70R17
• Overall diameter: 285/70R17 is ≈0.55 inches (≈1.7%) larger than 275/70R17

Because the diameter gap remains under ±3%, 285/70R17 and  275/70R17 sizes are usually interchangeable. Even so, the 285 adds enough section width that the rubbing risk often increases sooner than the raw diameter change suggests.
