Tire Size 315/75r16 vs 265/75r16

The main difference between 315/75R16 and 265/75R16 tires is the width. The 315/75r16 tires are 1.97 inches (50mm) wider than 265/75r16 tires.

This means that the 315/75R16 tire will have a wider footprint on the road, which can improve traction and handling.

265/75r16 vs 315/75r16

This table is designed to help you quickly understand the differences between the options.

Fitment Guide

Replacement tires should be within 3% of the original tire’s overall diameter to avoid clearance issues or speedometer inaccuracies.

The 315/75r16 diameter is 2.95 inches (75mm) larger than the 265/75r16, an 8.5% difference.

This exceeds the 3% limit, so the 315/75r16 may require modifications like a lift kit to prevent rubbing at a complete turn.

Ground Clearance

The taller 315/75r16 tire provides 2.48 inches (63mm) more ground clearance than the 265/75r16 size. This added clearance is useful for off-roading, helping avoid scrapes over obstacles.

However, the larger diameter also causes a lower speedometer reading. The 265/75r16’s reduced clearance increases the risks of scraping but gives a more accurate speedometer.

Gas Mileage

The narrower 265/75r16 tire will likely provide slightly better fuel efficiency than the 315/75r16.

With less rolling resistance and rotational mass, the 265 width confers efficiency benefits for daily driving and long trips. The wider, heavier 315 detracts from mileage.

Ride Comfort

The 315/75r16’s larger diameter and taller sidewall absorbs bumps and impacts better than the 265/75r16. This cushier ride is advantageous on rough, uneven terrain.

However, the 265/75r16 offers a smoother, more comfortable highway ride with its shorter sidewall and smaller contact patch.

Aesthetics

Visually, the difference is pronounced. The 315 width has a more aggressive, “stretched” look than the narrower 265 tires.

Trucks and SUVs often suit the wider presence, but drivers preferring a streamlined appearance may favor the 265.

Handling & Stability

The 265/75r16 provides quicker steering response and sharper handling due to its shorter sidewall and smaller contact patch.

But the 315/75r16’s larger footprint offers more excellent stability, especially off-road, where the extra grip and flex are beneficial.

Noise & Vibration

With more air volume and sidewall flex, the 315/75r16 dampens road noise and vibrations better than the 265/75r16.

However, both tires deliver a quiet, comfortable ride. The 265 transmits slightly more road feedback, but the differences are modest.

Durability & Wear

The narrower 265/75r16 exhibits potentially longer tread life and more even wear patterns than the wider 315/75r16.

The heavier 315 also stresses vehicle components more during rotation. However, the 315 withstands impacts better.

Adverse Conditions

In snow and ice, the narrower 265/75r16 can cut through to the road surface more effectively.

But in mud, sand, and deep snow, the wider 315/75r16 provides superior traction with its larger footprint. Both perform well in wet conditions.

Speedometer Reading

At an actual speed of 20 mph, the speedometer reads 18.29 mph with the 265/75r16 tire compared to 20 mph with the 315/75r16. This 1.71 mph difference is due to the smaller overall diameter of the 265 size.

What Is A 315 75r16 Equivalent To?

The tire size 315/75R16 is equals the tire size 34.6×12.4R16 in the high flotation system.

The 315/75R16 tire has a diameter of 34.6 inches (878 mm) and a tread width of 12.4 inches (315 mm). It can be mounted on a 16-inch (406 mm) wheel.

What Is A 265 75r16 Equivalent To?

The tire size 265/75R16 is equal to 31.7×10.4R16 when converted to inches.

The width of the 265/75R16 tire is 10.4 inches, which is the distance from its inner sidewall to its outer sidewall. Additionally, this tire can be mounted on a 16-inch wheel.

Our Observation
Based on the comparisons, the 315/75r16 is better for off-roading and rugged terrain. Its wider footprint, taller sidewall, and increased ground clearance give it superior traction and impact absorption for uneven surfaces.

However, the 265/75r16 excels for regular road use. Its narrower width provides sharper handling, potential fuel savings, and a more streamlined appearance ideal for paved roads.

Ultimately, we recommend the 315/75r16 tire for drivers who frequently go off-road or require maximum durability. The 265/75r16 is likely the better option for mainly highway use.
