Fitment Guide
It’s crucial to ensure the new size is within 3% of the original tire’s overall diameter. In this case, the 225/75R15 has a diameter that is 2% smaller than the 235/75R15, which falls within the acceptable range.
This means that switching from 235/75R15 to 225/75R15 should not cause any major fitment issues.
On-Road Impact
Switching to a slightly narrower tire like the 225/75R15 can have some effects on your vehicle’s on-road performance. Here are a few potential changes you might notice:
- Ride Comfort: The narrower tire may provide a slightly firmer ride due to reduced sidewall flex.
- Fuel Efficiency: The 225/75R15 tire will have a marginally lower rolling resistance, which could lead to a minor improvement in gas mileage.
- Handling: The narrower tire may offer slightly more responsive steering, particularly during initial turn-in.
- Speedometer Accuracy: The 2% difference in diameter will cause your speedometer to read about 2% faster than your actual speed. Keep this in mind when monitoring your speed.
Off-Road Impact
If you use your vehicle for off-road adventures, here’s what you might experience with the switch to 225/75R15 tires:
- Traction: The narrower tire may provide slightly less traction in loose terrain like mud or sand due to the reduced contact patch.
- Ground Clearance: The 0.59-inch (15 mm) reduction in overall diameter will slightly decrease your vehicle’s ground clearance, but this difference is generally negligible for most off-road situations.
- Sidewall Strength: The narrower tire will have a slightly shorter sidewall, which may marginally reduce the tire’s ability to absorb impacts from rocks or other obstacles.
What is the Main Difference Between 235/75r15 and 225/75r15?

Our Observation
After analyzing the differences between 235/75R15 and 225/75R15 tires, we believe that switching to the narrower size is a viable option for most vehicles.
The 2% difference in diameter and 4.3% difference in width are within acceptable ranges and should not significantly impact your vehicle’s performance or safety.
However, it’s essential to consider your specific driving needs and preferences. If you frequently drive in challenging off-road conditions or prioritize maximum traction and sidewall strength, sticking with the original 235/75R15 size might be the better choice.
