All You Need To Know About LT265/70R17 Tire Size

LT265/70R17 has a 265 mm section width, a 70% aspect ratio, fits a 17-inch wheel, and measures approximately 31.6 inches in overall diameter with a 185.5 mm, or 7.3-inch, sidewall. The LT prefix identifies LT265/70R17 as a Light Truck tire size. A verified 265/70R17 version has the same nominal dimensions, but its load capacity, inflation requirements, and service description must be checked separately; the LT tire designation guide explains these differences.

LT265/70R17 Alternative Tire Sizes

Drivers comparing LT265/70R17 alternatives frequently consider LT275/70R17 and LT285/70R17. LT275/70R17 is wider and slightly taller than LT265/70R17, with a relatively close overall diameter. LT285/70R17 is wider and taller, and its diameter exceeds that conservative guideline of 3% for passenger vehicles, yet still accepted for light trucks (+/- 5%). These dimensional results alone do not establish interchangeability; the ±3% tire-size guideline is only a starting point, and each LT265/70R17 alternative requires vehicle-specific verification.

LT265/70R17 vs LT275/70R17

LT275/70R17 has an overall diameter approximately 1.74% larger than LT265/70R17:

• Width Difference: LT275/70R17 is nominally 10 mm wider than LT265/70R17.
• Diameter Difference: LT275/70R17 is approximately 0.6 inches taller than LT265/70R17, an increase of 1.74%.
• Interchangeability: The LT275/70R17 diameter difference falls within the commonly used ±3% guideline (5% for Light Trucks), but this alone does not confirm interchangeability with LT265/70R17. Wheel width, load capacity, clearance, and vehicle requirements must still be checked.
• Practical Difference: LT275/70R17 adds 10 mm of nominal width and approximately 0.3 inches of tire radius compared with LT265/70R17.

LT265/70R17 vs LT285/70R17

LT285/70R17 has an overall diameter approximately 3.49% larger than LT265/70R17, placing the difference within the commonly used ±5% guideline for LT tire-size comparisons.

• Width Difference: LT285/70R17 is nominally 20 mm wider than LT265/70R17.
• Diameter Difference: LT285/70R17 is approximately 1.1 inches taller than LT265/70R17, an increase of 3.49%.
• Interchangeability: The 3.49% diameter difference between LT285/70R17 and LT265/70R17 remains within the ±5% guideline used for LT tire-size comparisons, leaving room for interchange. The 20 mm width increase and larger overall diameter still require confirmation of wheel-width compatibility, tire clearance, load capacity, inflation requirements, and vehicle specifications.
• Practical Difference: LT285/70R17 adds 20 mm of nominal width and approximately 0.6 inches of tire radius compared with LT265/70R17.
