275/65R17 Tire Size

All You Need to Know About 275/65R17 Tires

275/65R17 tires measure 275 mm in width, use a 65% aspect ratio, and mount on 17-inch wheels. This results in an overall diameter of approximately 31.1 inches, placing it in the same 31-inch truck tire category as many OEM fitments, but with a noticeably wider footprint. Industry standards support an approved rim width range of 7.5-9.5 inches, which aligns with wider factory and aftermarket truck wheel setups.

Compared to P265/70R17, the 275/65R17 size is slightly shorter but wider, making it a common upgrade when increasing road contact and lateral stability without significantly changing overall diameter.

Comparison of 275/65R17 With Similar Tire Sizes

Comparing 275/65R17 with similar tire sizes like P265/70R17 and 275/70R17 helps clarify how width and diameter changes affect fitment, clearance, and vehicle behavior.

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

The 275/65R17 is wider but slightly shorter in overall diameter compared to P265/70R17:

• 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%)

This means the 275/65R17 increases contact patch width and lateral grip, while P265/70R17 maintains slightly more ride height and cushioning. Because the diameter difference is small (~1.6%), both sizes are often interchanged, but width-related clearance must be verified.

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

The 275/70R17 maintains the same width but significantly increases sidewall height and overall diameter compared to 275/65R17:

• Width: identical (275 mm)
• Sidewall: 275/70R17 is ≈13.8 mm taller
• Diameter: 275/70R17 is ≈1.1 inches larger (~3.5%)

This ~3.5% increase pushes the 275/70R17 tire into the 32-inch class, improving ground clearance and off-road capability, but also increasing the likelihood of rubbing and affecting gearing.
