Tire Size 235/80r16 vs 235/85r16
Switching from 235/80R16 to 235/85R16 tires can bring some noticeable changes to your vehicle’s performance.
While both sizes have the same width, the diameter difference can affect ride quality, speedometer accuracy, and overall handling.
- Increased ground clearance helps navigate rough terrain more easily
- Taller sidewalls provide a smoother and more comfortable ride
- Enhanced off-road performance with better obstacle clearance
- Improved vehicle appearance with a more robust and muscular look
- Speedometer may display inaccurate speed readings
- Potential for tire rubbing against wheel wells or suspension components
- Reduced acceleration and responsiveness due to larger tire size
Fitment Guide
it’s crucial to note that the new tire’s diameter is within the acceptable 3% range of the original tire’s diameter. This means the switch is generally feasible without major modifications.
However, the 6.3% increase in sidewall height could potentially lead to issues such as rubbing or clearance problems, especially under full suspension compression or sharp steering maneuvers.
On-Road Impact
Switching to a 235/85R16 tire can influence various on-road characteristics. The slight increase in diameter leads to changes in ground clearance and speedometer accuracy.
- Ground Clearance: The taller tire increases the vehicle’s ground clearance, allowing for better performance over bumps and uneven terrain. This can enhance stability and make off-road driving more comfortable.
- Gas Mileage: Larger tires may slightly affect gas mileage. The additional diameter means more weight and potentially higher rolling resistance, which can lead to decreased fuel efficiency.
- Ride Comfort: The increased sidewall height can improve ride comfort by providing better shock absorption on rough roads, resulting in a smoother driving experience.
- Speedometer Accuracy: With the change in tire diameter, your speedometer reading will be off. For instance, at 20 mph, the speedometer may read 20.6 mph. This discrepancy can impact your driving experience, as you might unintentionally exceed speed limits.
Off-Road Impact
Switching to a 235/85R16 tire offers several advantages and considerations when it comes to off-road performance.
- Ground Clearance: The additional height is beneficial for off-road driving. It allows for better clearance over obstacles, reducing the likelihood of undercarriage damage.
- Durability & Wear: Larger tires can sometimes provide better durability, especially in rugged terrains. However, they may also lead to increased wear on suspension components due to the added height and potential strain.
- Aesthetics Look: Taller tires can enhance the appearance of your vehicle, giving it a more rugged look, which is often desirable for off-road enthusiasts.
- Ride Comfort: The increased sidewall height helps in cushioning impacts from rough surfaces, improving overall comfort on uneven trails.

However, you may need to adjust for clearance issues and be aware of potential speedometer inaccuracies.
How Much Taller is a 235/85r16 Tire Than a 235/80r16?
A 235/85R16 tire is approximately 0.93 inches taller than a 235/80R16 tire, offering increased ground clearance and a higher sidewall for better shock absorption.
How Much Wider is a 235/85r16 Tire Than a 235/80r16?
The 235/85R16 tire is the same width as the 235/80R16, both measuring 9.25 inches. This consistency helps maintain stable vehicle performance and handling.
Our Observation
Switching from 235/80R16 to 235/85R16 has its benefits and shortcomings. The increased diameter offers improved ground clearance, enhancing both on-road stability and off-road capability.
However, the change can also lead to a decrease in fuel efficiency due to higher rolling resistance. On the downside, the speedometer will read inaccurately, which could lead to unintentional speeding.
While the difference in handling is noticeable, many drivers may find the change negligible for everyday use.
Ultimately, if you’re considering this switch, be prepared for potential modifications to avoid clearance issues, especially if you frequently navigate tight spaces or urban environments.
