The 265 75r16 tire size is a metric designation. The first number, 265, refers to the width of the tire in millimeters. The second number, 75, refers to the height of the sidewall as a percentage of the width. The “R” in this case stands for radial construction, and the 16 refers to the wheel diameter in inches.
Tire Width
The width of the 305 70r16 tires is 12.10 inches or 305 millimeters, and the width of the 265 75r16 tires is 10.43 inches or 265 millimeters. When comparing these two sizes, the first thing you’ll notice is that the 305 70r16 tires are more comprehensive than the 265 75r16 tires.

Aspect Ratio
Aspect ratio is the second number in metric tire size. It’s expressed as a percentage of the width, and it tells you the height of the sidewall. For example, in a 265 75r16 tire, the height of the sidewall is 75% of the width of the tire. This means that the sidewall of the 265 75r16 tires is approximately 198.75 millimeters tall.
The aspect ratio of the 305 70r16 tires is 70, which means that the sidewall is approximately 213.50 millimeters tall. The taller sidewall of the 305 70r16 tires gives them a bigger contact patch, which is the area of the tire that touches the ground.
Construction Type
The last letter in a tire size designation is “R,” which stands for radial construction. Radial tires are the most common type of tire on the market today. They’re made with steel belts that run across the tread and provide strength and durability. Both the 305 70r16 and 265 75r16 tires are made with radial construction, so there is no difference in this aspect.
Rim Size
The last number in a tire size designation is the diameter of the wheel that the tire is meant to be used with. In our example, both tires are 16 inches in diameter. Suppose you’re unsure about what size wheels you have on your vehicle. In that case, you can usually find this information on the placard that is located on the driver’s side doorjamb.

The 265 75r16 tires have an RPM of approximately 637.23. As you can see, the 305 70r16 tires have a slightly higher RPM than the 265 75r16 tires.
Our Observation
Now that we’ve gone over the basics of tire sizes let’s talk about the pros and cons of each size. The wider width of the 305 70r16 tires gives them a bigger contact patch, which means they have more traction. They also have a taller sidewall, which provides them with a smoother ride. However, the taller sidewall also means that they’re more susceptible to damage from road debris.
The 265 75r16 tires are narrower and have a shorter sidewall. This makes them lighter and more agile than the 305 70r16 tires. They’re also less likely to be damaged by road debris. However, the shorter sidewall means that they have a harsher ride.
