  • A tire with a higher circumference gives better mileage, which means you can travel more distances with less fuel consumption. 

With a circumference of 108.71 inches, the 315 75r16 tire is significantly larger than its counterpart 265 75r16, which has a measurement of 99.43 inches – a 9.28 inches big difference. This extra size gives you far better mileage when taking long journeys.

Section Width

  • The section width of the tire indicates how wide the tire is.
  • It greatly impacts the tire grip, traction, and smooth rolling.

In section width, 315 75r16 tire is 12.40 inches wide, and 265 75r16 tire is 10.43 inches wide. It means the 315 75r16 tire size is 1.97 inches wider. When it comes to grip, 315 tire gives more grip than 265 tires.

Rim diameter

  • Rim diameter means the outer parameter of the wheel.
  • It greatly affects the overall performance and stability of the tire.

Both 315 75r16 vs. 265 75r16 has the same rim diameter of 16 inches, so you don’t have to worry about compatibility issue.

Sidewall height

  • Sidewall height means the height of tires from the wheel rim to the tread.
  • Tires with higher sidewalls give more comfortable riding even on bumpy roads.

The sidewall height of a 315 75r16 tire is 9.30 inches, while its 265 75r16 counterpart stands at 7.82 – giving you an extra 1.48-inch cushion when driving on bumpy roads for smoother rides. However, you may feel some vibration due to this additional sidewall height.

Construction Type

  • Tire construction type is a term that describes the manufacturing process and purpose for which the tire was created.
  • Regarding the construction type, the performance varies on different roads.

The construction type of 315 75r16 and 265 75r16 tire size is radial. They both have the same manufacturing process and provide a comfortable ride on dry roads.

However, due to the additional width, the 315 75r16 tire gives better grip and stability than its counterpart in wet conditions.

Revs Per Mile (RPM)

  • The Revs or revolution per mile (RPM) of a tire means how many times a tire will rotate for each mile it travels.
  • A higher RPM gives better fuel consumption, as the engine needs less effort to rotate the tires.

The 315 75r16 tire has an RPM of 582.85, and its 265 75r16 counterpart stands at 637.23. So, the 315 75r16 tire is more efficient since it has 54.38 less RPM than the other tire.

Aspect ratio

  • A tire aspect ratio is the ratio of the sidewall height to the section width.
  • The more aspect ratio, the more comfortable and enjoyable your ride will be.

The aspect ratio of the 315 75r16 tire is 75, and the 265 75r16 tire is also 75. This means there is no difference between their aspect ratios. However, when it comes to sidewall height, 315 tires are higher than the other one.

Approved Rim Width

  • Approved or recommended rim width of a tire means the width of the rim that you should use for the best performance of the tire.
  • By selecting a rim width that is not approved, you risk shortening the tire lifespan and reducing traction on the road.

The recommended rim width for the 315 75r16 tire size is 8.0 – 10.00 inches, and 7.0-8.0 inches for the 265 75r16 tires. So, you should use a smaller width rim for the latter one.


  • Tire radius means the distance from the center of a wheel to its outer edge.
  • It is measured as half of the overall diameter.

The radius of a 315 75r16 tire is substantially larger than the 265 75r16, measuring 17.3 inches compared to 15.825 inches, respectively. This difference of 1.475 inches in favor of the former makes it quite worth considering if you’re looking for optimal performance and reliability.

  • The tire pressure refers to the amount of air inside the tire.
  • Tire pressure has a great effect on tire performance and fuel economy.

The load range (C, D, and E) of both 315 75r16 and 265 75r16 tires yield three disparate classes. As seen in the accompanying chart, the maximum tire pressure for a Load Range C 315 75R16 is 35 PSI, while that of a 26575R16 is 60 PSI – this marks an important differentiation between the two types. Even there exist 15 PSI differences among other ranges as well.

Speedometer Reading

  • The speedometer of the tire is the reading of the tire’s actual speed in terms of miles or kilometers per hour.
  • Speedometer reading varies on different tires due to their size.

The 315 75r16 and 265 75r16 tires have a 9.35% disparity in speedometer reading. To put that into perspective, when driving at 10 mph with the former set of tires, you’ll feel like you’re going 0.935 mph faster if fitted with the latter – making your total speed 10.935 mph.

Other Details Of 315 75r16 Vs 265 75r16 Tire Size

Here are the details of the additional differences – outlined in the previous chart. Read thoroughly to know them properly.

Load Capacity

  • A tire’s load capacity means the maximum amount of weight it can take without compromising its performance.
  • To measure your tire’s maximal loading capabilities, you must pump the tires to their designated pressure and drive them at full velocity.

You already know that both the 315 75r16 and 265 75r16 tires come in 3 different load ranges. For example, a 315 75R16 C range tire can hold up to 2535 lbs, while a 265 75R16 C range tire can hold up to 2470 lbs. This is a difference of 66 lbs. 

The D range tire for a 315 75r16 can take a weight of 3195 lbs, while the other can only hold 3000 lbs. This means that the D range 315 tires can take 195 lbs more weight than the other.

And, when it comes to E-range tires, the 315 75r16 can hold up to 3860 lbs, which is 445 lbs more capacity than the 265 75r16, which can hold up to 3415 lbs.

Tread Depth

  • The tread depth of a tire means the grooves and tread blocks of a tire.
  • Tread depth is the most important factor when it’s about to get more lifespan of a tire.

The 315 75r16 tire has a tread depth of 21/32, and the 265 75r16 tire has a tread depth of 18/32. So, the difference between them is 3, meaning that if you want better performance from your tires and more longevity, you should go for the 31575R16 model.

Grip on road

  • The grip of a tire depends on its width, tread, and pattern of it.
  • The wider the tire and deeper the tread, the better grip it will provide on wet roads and snow-covered roads.

The 315 75r16 tire is better than the 265 75r16 in this regard. The wider surface area and deeper tread of the 315 series give it a superior grip over the 265 series, making it more suitable for wet roads, icy conditions, and off-road driving.

Speed Rating

  • The speed rating of a tire denotes the maximum speed at which it can be safely driven.
  • This rating can be identified from the Letter of the tire model name.

With the Q series 315 75416 tires, you can travel up to a maximum speed of 160 kph. But if you opt for the R series 265 75r15 tire instead, then your rate of acceleration is even higher – reaching an impressive 170 kph. This differs in terms of speed, model design, and capabilities.


  • Ground clearance of a tire means the distance between the road and the lowest point of a tire.
  • It also means, after installing a tire, how much gap is there between the road and the fender.

By upgrading your 265 75r16 tires to 315 75r16s, you’ll experience a significant boost in ground clearance of 38.00 mm. The additional height will be especially useful for navigating rough terrain, providing improved vehicle performance and stability.

Traction Rating

  • The traction rating of a tire indicates its performance level on wet and dry roads.
  • It also impacts the grip and control of the tire on different roads.

The 315 75r16 and 265 75r16 tires have a uniform traction rating of A in any weather. This indicates that both will offer similar amounts of grip and traction on the road.

Tire Price

  • Tire price is an important factor when deciding to purchase one.
  • It is a sign of affordability.

If you’re looking for a way to save money on tires, the 265 75r16 is the best choice at only $47.99 in starting price.

But if load capacity, RPM, more grip, and speedometer reading are important considerations for you, then the 315 75r16 might be a better option despite its higher starting cost of $140.26.

315 75r16 Vs 265 75r16 tire size: Our Recommendation
