Tire Size 225/75r16 vs 235/70r16
These tire sizes may seem similar, there are some important differences to consider before making the change. We’ll explore the key factors you need to know to make an informed decision.
- Increased tire width improves handling and stability
- Slightly reduced overall diameter minimally affects ground clearance
- Minor speedometer inaccuracy of 0.23 mph at 20 mph
- Wider tires may slightly decrease fuel efficiency
- Enhanced traction on loose off-road surfaces like sand or gravel
- Possible improvement in durability and puncture resistance
Fitment Guide
It’s crucial to ensure that the new tires’ overall diameter is within +3 of the original tires.
In this case, the diameter difference between 225/75R16 and 235/70R16 tires is -1.1%, which falls within the acceptable range.
However, it’s still important to consider other factors before proceeding with the switch.
On-Road Impact
Switching to wider 235/70R16 tires can have both positive and negative effects on your vehicle’s on-road performance. Let’s explore some of the key areas:
- Ride Comfort: The wider tires may slightly improve ride comfort by providing a larger contact patch with the road surface, helping to absorb bumps and vibrations.
- Handling: The increased width of the 235/70R16 tires can enhance your vehicle’s handling, particularly in dry conditions, by offering better grip and stability during cornering.
- Speedometer Accuracy: Due to the slight difference in tire diameter, your speedometer reading may be affected. At 20 mph (32.19 km/h), your actual speed will be 19.77 mph (31.82 km/h), which is a negligible difference.
- Fuel Efficiency: The wider tires may cause a slight decrease in fuel efficiency due to increased rolling resistance. However, the impact is likely to be minimal.
Off-Road Impact
If you plan to take your vehicle off-road, the switch to 235/70R16 tires can offer some benefits, but there are also some drawbacks to consider:
- Ground Clearance: The slightly smaller overall diameter of the 235/70R16 tires may result in a minor reduction in ground clearance (-0.33 inches or -8.5 mm). This difference is unlikely to have a significant impact on most off-road situations.
- Traction: The wider tires can provide better traction on loose surfaces like sand or gravel, thanks to the increased contact area with the ground.
- Durability: Depending on the specific tire model and brand, the 235/70R16 tires may offer better durability and puncture resistance due to their wider profile and potentially thicker sidewalls.
