P265/70R17 Tire Size

All You Need to Know About P265/70R17 Tires

P265/70R17 tires measure 265 mm in width, use a 70% aspect ratio, and mount on 17-inch wheels. This configuration results in an overall diameter of approximately 31.6 inches, placing it in the common 31-32 inch truck tire class used on midsize pickups and traditional SUVs. Industry standards support a 7.0-9.0 inch rim width range, which aligns with typical OEM wheel widths on vehicles like the Tacoma and 4Runner.

P265/70R17 Quick Specs

• Overall diameter: ≈31.6 in
• Sidewall height: ≈186 mm
• Section width: 265 mm
• Rim width range: 7.0-9.0 in
• Wheel diameter: 17 in

Note: The calculated overall diameter of P265/70R17 is ≈31.6 inches. Actual mounted diameter can vary slightly (±0.1-0.3 inches) depending on tread design, manufacturer specs, and whether the tire is P-metric or LT-rated.

Common Vehicle Fitments for P265/70R17

P265/70R17 is a widely documented OEM and replacement size for midsize trucks and ladder-frame SUVs, where a taller sidewall improves ride compliance without exceeding factory gearing limits.

• Toyota Tacoma (2005-2023, SR / SR5 / TRD trims)
• Toyota 4Runner (2003-2024, base and SR5)
• Ford Ranger (2019-2023)
• Chevrolet Colorado (2015-2022)
• GMC Canyon (2015-2022)
• Nissan Frontier (2005-2024)
• Jeep Grand Cherokee (WK / WK2 base fitments)
• Isuzu D-Max / MU-X (global spec platforms)

These trucks and SUVs are engineered around a 31-to-32-inch tire diameter. Because the P265/70R17 sits right in that sweet spot, it's a "plug-and-play" size that keeps your speedometer accurate and ensures the transmission shifts exactly how the factory intended.

P265/70R17 Dimensions in Inches

A P265/70R17 tire converts to approximately 31.6 inches in overall height, 10.4 inches in width, and a 7.3-inch sidewall, which explains its balance between ride comfort, ground clearance, and load stability.

P265/70R17 in inches: all measurements

• Overall diameter: ≈31.6″
• Sidewall height: ≈7.30″
• Section width: ≈10.43″
• Circumference: ≈99.3″

P265/70R17 in inches: 31.6″ × 10.4″ R17

The P265/70R17 size sits in a critical transition zone between smaller crossover sizes (~29-30") and larger off-road upgrades (~32-33"), which is why it is often used as a baseline for upsizing decisions.

Comparison of P265/70R17 With Similar Tire Sizes

Comparing P265/70R17 with similar tire sizes like 275/65R17 and 265/65R17 highlights how small changes in width and sidewall height affect clearance, ride quality, and overall gearing.

Difference Between P265/70R17 and 275/65R17 Tire Sizes

The P265/70R17 is slightly taller, while the 275/65R17 increases width but reduces sidewall height slightly.

• Width: 275/65R17 is 10 mm wider
• Sidewall: P265/70R17 is ≈6.7 mm taller
• Diameter: P265/70R17 is ≈0.5 inches larger (~1.6%)

In practical terms, the wider 275/65R17 provides a broader contact patch, which can improve traction under load, while the P265/70R17 maintains slightly more ride height and vertical compliance. Because the diameter difference stays within ~3%, this swap is generally considered safe, but clearance at full steering lock and wheel offset should still be verified.

Difference Between P265/70R17 and 265/65R17 Tire Sizes

The P265/70R17 keeps the same width but uses a taller sidewall, resulting in a noticeably larger overall diameter compared to 265/65R17.

• Width: identical (265 mm)
• Sidewall: P265/70R17 is ≈13.3 mm taller
• Diameter: P265/70R17 is ≈1.0 inch larger (~3.3%)

This difference is more significant. The taller P265/70R17 increases ground clearance and ride cushioning, while the 265/65R17 lowers the vehicle slightly and tightens gearing, which can improve acceleration but reduce off-road capability. At ~3.3%, this change sits right at the edge of acceptable tolerance, meaning fitment and speedometer impact should be evaluated carefully.
