Tire Size 235/75r16 vs 245/75r16
Upgrading from a 235/75R16 to a 245/75R16 tire may seem minor, but it’s crucial to understand exactly how these changes affect your driving experience. This guide delves into these differences, helping you decide whether to switch.
- Wider tires provide better grip on various road surfaces
- Enhanced stability improves handling during turns
- Increased ground clearance helps navigate rough terrains more easily
- Taller sidewalls offer a smoother and more comfortable ride
- Fuel efficiency may decrease slightly due to larger tire size
- Potential for clearance issues if the vehicle isn’t properly fitted
Fitment Guide
The diameter of the 235/75R16 tire is 29.88 inches (758.9 mm), while the 245/75R16 tire measures 30.47 inches (773.9 mm). The difference of 0.59 inches (15 mm) is about 2%, making this switch acceptable.
However, if the difference exceeded the 3% threshold, it would not be recommended without additional adjustments to prevent issues such as rubbing or clearance problems.
On-Road Impact
Switching to a wider tire can significantly affect how your vehicle handles on the road. A wider tire generally offers:
- Increased traction: The larger contact area provides better grip, especially during cornering.
- Improved stability: Wider tires can enhance stability at high speeds, making them safer for highway driving.
- Speedometer accuracy: The 245/75R16 tire will rotate fewer times per mile due to its larger circumference, leading to a slight increase in speedometer reading accuracy. For example, at 20 mph, the actual speed may read 20.4 mph, reflecting this difference.
While these advantages are appealing, it’s important to note that there might be a slight reduction in gas mileage due to the increased rolling resistance. However, this difference may not be significant enough to cause concern for most drivers.
Off-Road Impact
For off-road enthusiasts, the benefits of switching to 245/75R16 tires are even more pronounced:
- Ground clearance: The increased tire height can improve ground clearance, allowing your vehicle to navigate rough terrain more effectively.
- Ride comfort: A larger sidewall height can absorb bumps and irregularities in the terrain better than a narrower tire, leading to a smoother ride off-road.
- Durability: Wider tires can provide better support when driving over rocks and obstacles, reducing the risk of sidewall damage.
However, the negligible differences in off-road performance may vary depending on the specific conditions. If you’re primarily driving on smooth trails or pavement, the advantages may not be as noticeable.

What is the Main Difference Between 235/75r16 and 245/75r16?
The main difference between the 235/75R16 and 245/75R16 tires lies in their width and sidewall height. The 245/75R16 tire is wider by 0.39 inches (10 mm) and has a slightly taller sidewall.
This results in a more substantial contact patch with the road, which can enhance traction and stability.
Can I Use 245/75r16 Instead of 235/75r16?
Yes, you can use 245/75r16 instead of 235/75r16 as the diameter difference is within the acceptable range of 3%, ensuring that fitment is feasible without major vehicle modifications.
How Much Taller Is a 245/75r16 Tire Than a 235/75r16?
A 245/75r16 tire is taller than a 235/75r16 by approximately 0.3 inches, which translates to about 4.3% in terms of sidewall height, providing better clearance and a smoother ride.
How Much Wider is a 245/75r16 Tire Than a 235/75r16?
The 245/75r16 tire is wider than the 235/75r16 by about 0.39 inches or 4.3%, which increases the contact patch with the road for improved traction and handling stability.
Our Observation
Switching from 235/75R16 to 245/75R16 tires offers several benefits, including enhanced traction, stability, and comfort both on and off the road.
The 0.59-inch diameter difference is within the acceptable range, making this switch feasible without major modifications.
However, while on-road performance may improve due to increased grip and slightly better speedometer accuracy, you might experience a slight decrease in fuel efficiency.
Off-road, the added ground clearance and ride comfort can significantly enhance your driving experience, making it easier to tackle rugged terrains.
Nevertheless, for everyday driving, the changes may feel negligible to some, so it’s essential to weigh your specific driving needs before making the switch.
