P275/65R17 Tire Size

All You Need to Know About P275/65R17 Tires

The “P” prefix identifies the P275/65R17 as a P-metric (passenger-rated) tire, meaning it is engineered for ride comfort, lower rolling resistance, and everyday driving, rather than maximum load capacity. While the external size matches 275/65R17 (no prefix) and LT275/65R17, the internal construction and load behavior are different.

P275/65R17 Size Quick Specs (P-Metric)

• Approved rim width range: 7.5–9.5 in
• Overall diameter: ≈31.1 in
• Section width: 275 mm
• Sidewall height: ≈179 mm
• Wheel diameter: 17 in
• Load rating: Typically Standard Load (SL) 
• Some models available in Extra Load (XL)

Note: The calculated overall diameter of P275/65R17 is ≈31.1 inches. Actual mounted size may vary slightly depending on manufacturer's construction, tread design, and whether the P275/65R17 tire is standard load (SL) or extra load (XL).

Common Vehicle Fitments for P275/65R17

Full-size truck and SUV platforms, including the Chevrolet Silverado 1500, GMC Sierra 1500, Ford F-150, Ram 1500, Toyota Tundra, and Nissan Titan, may use P275/65R17 in standard-load, non-towing configurations, depending on the trim and factory specification.

P275/65R17 does not correspond to a separate set of vehicles from the 275/65R17 designation, as both share the same overall dimensions. The P-metric designation reflects the tire’s load standard and intended use, not a different fitment group: P275/65R17 is typically suited for light-duty, comfort-oriented applications. 

P275/65R17 Dimensions in Inches

A P275/65R17 tire is about 10.8 inches wide, 31.1 inches tall, and features a 7.0-inch sidewall height, providing increased ride cushioning compared to smaller 30-inch class sizes such as 265/65R17 (≈30.6") or 255/70R17 (≈30.9").

P275/65R17 in inches: All Measurements (P-metric)

Comparison of P275/65R17 With Similar Tire Sizes

Comparing P275/65R17 with similar tire sizes like 275/65R17 and 275/60R17 highlights how tire designation and diameter affect load capacity, ride comfort, and fitment.

Difference Between P275/65R17 and 275/65R17 Tire Sizes

The key difference lies in load rating methodology: when used on trucks and SUVs, P-metric tires (P275/65R17) are typically derated by a factor of 1.10, resulting in about 9% lower effective load capacity compared to a non-P-metric tire of the same load index.

The 275/65R17 designation generally refers to standard (non-P) passenger or Euro-metric tires, while LT275/65R17 represents a separate light-truck construction with higher load capacity and a stiffer casing designed for towing and heavy-duty use. P-metric tires (P275/65R17) may be available in Standard Load (SL) or Extra Load (XL), but do not use LT load range classifications.

Difference Between P275/65R17 and 275/60R17 Tire Sizes

The 275/60R17 is slightly smaller in diameter, with a shorter sidewall compared to  P275/65R17:

• Sidewall: P275/65R17 is ≈13.8 mm taller than 275/60R17 
• Diameter: P275/65R17 is ≈1.1 inches larger (~3.7%) than 275/60R17

The ~3.7% diameter difference between P275/65R17 and 275/60R17 exceeds the 3% rule, meaning tire sizes can’t be replaced without verifying fitment and speedometer impact.
