Fitment Guide
It’s crucial to ensure that the overall diameter difference falls within the acceptable range of 3%. In this case, the diameter difference is 1.4%, which is well within the limit. As a result, the interchange between these two tire sizes is generally recommended without requiring any significant adaptations.
On-Road Impact
Switching to 255/75R17 tires can have several effects on your vehicle’s on-road performance. Here’s what you can expect:
- Ride Comfort: The taller sidewall of the 255/75R17 tires provides a bit more cushioning, which can lead to a slightly smoother ride, especially on bumpy roads.
- Handling: The narrower width of the 255/75R17 tires may result in a minor reduction in handling responsiveness, particularly during cornering or sudden maneuvers. However, this difference is likely to be barely noticeable to most drivers.
- Speedometer Accuracy: The 1.4% difference in revolutions per mile will cause a slight speedometer discrepancy. At a indicated speed of 20 mph (32.19 km/h), your actual speed would be 20.29 mph (32.65 km/h). This difference is negligible and unlikely to cause any issues.
- Fuel Efficiency: The narrower width and taller sidewall of the 255/75R17 tires may provide a small improvement in fuel efficiency due to reduced rolling resistance.
Off-Road Impact
If you frequently take your vehicle off-road, switching to 255/75R17 tires can offer some advantages:
- Ground Clearance: The taller sidewall of the 255/75R17 tires will slightly increase your vehicle’s ground clearance by about 0.23 inches (5.75 mm). While this difference is minimal, it can be beneficial when navigating rough terrain or obstacles.
- Traction: The narrower width of the 255/75R17 tires can provide better traction in soft surfaces like mud or sand, as the weight of the vehicle is concentrated on a smaller area, allowing the tires to dig in more effectively.
- Durability: The taller sidewall of the 255/75R17 tires offers more flexibility and protection against damage from rocks, roots, and other off-road hazards.
What is the Difference Between 265/70R17 and 255/75R17?
