What Does 265/70r17 vs 265/65r17 Tire Mean?
First and foremost, the 265/65R17 and 265/70R17 tire sizes are the tire specifications established during production.
You may find this information easily in the owner’s handbook for your car or in a few other places, such as the door frame standing next to the driving seat, under the glove box cover, or on the gasoline tank cap.
When you read the numbers from left to right, you will see that the first figure is the tire’s width as measured in millimeters.
Aspect ratio, or the ratio between its height and width, is represented by the second digit. You can follow the third letter as the type of construction, and the fourth value indicates the tire’s diameter in inches.
What is the difference between 265 65r17 and 265 70r17? A quick chart specifically interprets the parameter’s values as described in the following:
| Meaning | 265 65r17 | 265 70r17 |
| Tire width in millimeters | 265 | 265 |
| The height/width aspect ratio | 65 | 70 |
| Type of construction | R | R |
| The wheel’s (or rim’s) diameter | 17 | 17 |
What Is The Difference Between 265 65r17 vs 265 70r17?
Overall diameter, section width, circumference, sidewall height, revolutions per mile, construction type, wheel size difference and clearance, show the distinctions between the tires.
Let’s scroll down to receive the information if you want to make comparisons of these tires in more detail:
Overall Diameter
The 265 65r17 diameter has a 30.6-inch measurement, compared to 31.6 inches for the 265 70r17 tires.
These two sizes don’t differ that much from each other. Nevertheless, it is something to bear in mind while making a choice.
Why? That is because a tire’s overall diameter equals the sum of the tire’s sidewall height and the diameter of the wheel.
Understanding this is crucial as it may impact how well your tires fit. Your automobile might be unable to accommodate a tire with a lower diameter.
But wait – not that’s all. A wheel with a greater diameter may be heavier, which will cause a little reduction in speed when accelerating.
The too big tire is also one of the reasons why your car sounds like a lawn mower.
Section Width
What makes tire width crucial? The tire width will influence the price and several other features, like grip, noise level, comfort while driving, and appearance.
Fortunately, the section width of the 265 70r17 and the 265/65r17 tires is 10.4 inches. The difference between those two tire sizes is zero.
However, if the tire widths differ in inches, we recommend replacing the narrow tire with the wider one. That will normally reduce rolling resistance and fuel usage.
Circumference
Since each car’s computer is programmed by the size of the tires affixed to the vehicle, the circumference will change depending on various parameters such as distance and current speed.
Your speedometer might not be correct if the circumference of your fantastic tires are not on par with what the manufacturer suggested.
The 265 70r17 tires’ circumference is 99.3 inches, whereas the 265 65r17 tires’ circumference measures 96 inches. The difference is about 3.3 inches or roughly 3.4%.
Revolutions Per Mile
The 265 70r17 tires turn 638.1 revolutions per mile, whereas that number is 659.9 revolutions per mile for the 265 65r17. These two tire sizes differ by 31.8 revolutions per mile or around 3.3%.
The number of revs per mile may impact your vehicle’s fuel efficiency. Typically, a tire with fewer miles per revolution has greater fuel efficiency than a tire with more miles per revolution.
For individuals looking to reduce their fuel expenditure in this situation, the 265 70r17 is a wise choice.
Sidewall Height
A taller sidewall often provides a smoother ride than a shorter sidewall. The difference in sidewall height between the 265 65r17 and 265 70r17 tires is 0.5 inches, representing nearly 7.7%.
Additionally, the taller sidewall doesn’t improve grip, but it reduces the chance that a wheel would flex if you hit a pothole or curb.
That is a typical justification for using a smaller wheel and a taller tire during winter.
Construction Type
Radial structure, also known as R, is the most widely used tire and an automobile industry standard. B, D, or E are the possible additional ratings.
The indication may impact your tires’ ability to ride smoothly. When compared to non-radial tires, radial type tires often offer a smoother ride.
Thankfully, there isn’t much uncertainty, as the 265 65r17 and the 265 70r17 tires are made of radial materials.
Radial tires provide excellent traction on the road, even though they might not be the ideal choice for off-road driving.
Wheel Size
Two actual tire sizes that fit 17-inch wheels are 265 70r17 and 265 65r17.
If you have fantastic tires with a smaller diameter, your vehicle may not be able to handle them due to the wheel size’s potential influence on how well your tires cooperate.
In truth, these two choices are more comfortable, quieter, and less expensive with the 17-inch wheels.
