All You Need To Know About LT285/70R17 Tire Size

LT285/70R17 has a 285 mm section width, a 70% aspect ratio, fits a 17-inch wheel, and produces an overall diameter of approximately 32.7 inches with a sidewall approximately 7.9 inches high. A P285/70R17 version exists with the same nominal dimensions, but its passenger-tire designation follows different load and inflation standards from LT285/70R17. Review the differences between LT and P-metric tires and confirm the required load capacity and inflation pressure before considering either designation.

LT285/70R17 Alternative Tire Sizes

Drivers comparing LT285/70R17 alternatives frequently consider LT275/70R17 and LT295/70R17. LT275/70R17 is narrower and slightly shorter than LT285/70R17, while LT295/70R17 is wider and slightly taller. Both alternatives remain within the applicable ±5% LT overall-diameter guideline, leaving room for interchange after vehicle-specific checks. This dimensional result alone does not establish compatibility; wheel width, load capacity, load range, inflation requirements, clearance, gearing, drivetrain requirements, and the vehicle manufacturer’s tire specifications still require verification.

LT285/70R17 vs LT275/70R17

LT275/70R17 has an overall diameter approximately 1.69% smaller than LT285/70R17, which is within the applicable ±5% guideline for LT tire-size comparisons.

• Width Difference: LT275/70R17 is nominally 10 mm narrower than LT285/70R17.
• Diameter Difference: LT275/70R17 is approximately 0.6 inches smaller in overall diameter than LT285/70R17, a difference of 1.69%.
• Interchangeability: The LT275/70R17 diameter difference falls within the applicable ±5% LT guideline and leaves room for interchange with LT285/70R17, but the percentage alone does not confirm complete vehicle compatibility. Verify approved wheel-width compatibility, load capacity and load range, required inflation pressure, radial and lateral clearance, speedometer and odometer effects, gearing and drivetrain requirements, and vehicle-specific tire requirements.
• Practical Difference: LT275/70R17 reduces nominal section width by 10 mm and complete tire height by approximately 0.6 inches compared with LT285/70R17.

LT285/70R17 vs LT295/70R17

LT295/70R17 has an overall diameter approximately 1.69% larger than LT285/70R17, which is within the applicable ±5% guideline for LT tire-size comparisons.

• Width Difference: LT295/70R17 is nominally 10 mm wider than LT285/70R17.
• Diameter Difference: LT295/70R17 is approximately 0.6 inches larger in overall diameter than LT285/70R17, a difference of 1.69%.
• Interchangeability: The LT295/70R17 diameter difference falls within the applicable ±5% LT guideline and leaves room for interchange with LT285/70R17, but the percentage alone does not confirm complete vehicle compatibility. Verify approved wheel-width compatibility, load capacity and load range, required inflation pressure, radial and lateral clearance, speedometer and odometer effects, gearing and drivetrain requirements, and vehicle-specific tire requirements.
• Practical Difference: LT295/70R17 adds 10 mm of nominal section width and approximately 0.6 inches of complete tire height compared with LT285/70R17.
