Tire Size 215/65r16 vs 215/70r16
While the difference in size may seem small, it can have a noticeable impact on your vehicle’s performance and handling. Let’s explore the key differences between these two tire sizes and what you need to know before making the switch.
- Taller sidewall provides improved ride comfort and off-road compliance
- Overall diameter increases by 0.85″ for slightly more ground clearance
- Steering response and on-road handling may be reduced due to taller sidewall flex
- Speedometer will read about 3% slower and gearing is effectively 3% taller
- Borderline 3.1% diameter difference may require minor modifications to avoid rubbing
215/65r16 vs 215/70r16 Table
The main difference between 215/65R16 and 215/70R16 tires is the sidewall height. The 215/70R16 has a sidewall that is 0.42″ (10.75 mm) taller than the 215/65R16.
Fitment Guide
The diameter difference between the original and replacement tires should not exceed 3%. In this case, the diameter difference between 215/65R16 and 215/70R16 tires is 3.1%, which slightly exceeds the acceptable range.
While you can still make the switch, be aware that some adaptations may be necessary to prevent rubbing or clearance issues.
On-Road Impact
Switching to taller 215/70R16 tires can have several effects on your vehicle’s on-road performance. Here are some key aspects to consider:
- Ride Comfort: The taller sidewall of the 215/70R16 tires may provide a slightly smoother ride, as the increased tire volume can better absorb road imperfections and vibrations.
- Speedometer Accuracy: Because the 215/70R16 tires have a larger diameter, they will rotate fewer times per mile than the 215/65R16 tires. This means your speedometer will read slightly slower than your actual speed. At 20 mph (32.19 km/h), your actual speed will be 20.63 mph (33.2 km/h).
- Fuel Efficiency: The taller sidewall of the 215/70R16 tires may slightly reduce your vehicle’s fuel efficiency due to increased rolling resistance.
- Handling: The taller sidewall of the 215/70R16 tires may result in a slightly less responsive steering feel compared to the 215/65R16 tires.
Off-Road Impact
If you plan to take your vehicle off-road, the switch to 215/70R16 tires can offer some advantages:
- Ground Clearance: The taller sidewall of the 215/70R16 tires will slightly increase your vehicle’s ground clearance, which can be beneficial when navigating rough terrain or obstacles.
- Traction: The larger tire volume of the 215/70R16 tires allows for a larger contact patch with the ground, potentially improving traction in loose or uneven surfaces.
What is the Difference Between 215/65R16 and 215/70R16?
The main difference between 215/65R16 and 215/70R16 tires is the sidewall height. The 215/70R16 tires have a taller sidewall, which is 0.42 inches (10.75 mm) or 7.7% taller than the 215/65R16 tires.
This difference in sidewall height contributes to the overall diameter difference of 0.85 inches (21.5 mm) or 3.1% between the two tire sizes.
Can I Use 215/70R16 Instead of 215/65R16?
While it is possible to use 215/70R16 tires instead of 215/65R16 tires, it is not highly recommended. The diameter difference between these two tire sizes is 3.1%, which slightly exceeds the generally accepted 3% range.
Exceeding this range may require adaptations to prevent potential issues such as rubbing or clearance problems. It is always best to consult with a professional tire technician or your vehicle’s manufacturer before making any changes to your tire size.
How Much Taller Is a 215/70R16 Tire Than a 215/65R16?
A 215/70R16 tire is 0.85 inches (21.5 mm) taller than a 215/65R16 tire. This difference in height is due to the taller sidewall of the 215/70R16 tire, which is 0.42 inches (10.75 mm) or 7.7% taller than the sidewall of the 215/65R16 tire.
The overall diameter of the 215/70R16 tire is 27.85 inches (707.4 mm), while the overall diameter of the 215/65R16 tire is 27 inches (685.9 mm).
Our Observations
After analyzing the differences between 215/65R16 and 215/70R16 tires, we believe that the impact of switching will be noticeable but not drastic. On-road, you may experience a marginally smoother ride, but with a slight reduction in fuel efficiency and steering responsiveness.
Off-road, the taller sidewall can provide a small increase in ground clearance and traction. Ultimately, the decision to switch depends on your specific needs and preferences.
If you prioritize off-road performance and a softer ride, the 215/70R16 tires may be a good choice. However, if you prefer a more responsive on-road feel and don’t need the extra ground clearance, sticking with the 215/65R16 tires may be the better option.
