What Does 265/65R17 Mean?
The tire size 265/65R17 is a common size used on many trucks, SUVs, and other larger vehicles.
Here is what each part of the size designation represents:
- 265: This number represents the width of the tire in millimeters. In this case, the tire is 265 millimeters wide.
- 65: This number represents the aspect ratio of the tire, which is the height of the tire's sidewall as a percentage of its width. In this case, the sidewall height is 65% of the tire's width.
- R: This letter indicates the tire's construction type. “R” stands for radial construction, which is the most common type of tire construction today.
- 17: This number represents the diameter of the wheel that the tire is designed to fit on, in inches. In this case, the tire is designed to fit on a 17-inch wheel.

How To Convert 265/65R17 Into Inches
The 265/65R17 conversion is fairly simple. The first number in the tire size, 265, represents the width of the tire in millimeters. To convert this to inches, we divide 265 by 25.4 (since there are 25.4 millimeters in an inch). This gives us approximately 10.4 inches.
The second number in the tire size, 65, represents the aspect ratio or the height of the tire as a percentage of its width. To calculate the height in inches, we multiply 10.4 by 0.65, which gives us approximately 6.8 inches.
Finally, the last number in the tire size, 17, represents the diameter of the wheel rim in inches. Therefore, the tire size 265/65R17 can be expressed in inches as roughly 10.4 inches wide, 6.8 inches tall, and designed to fit a 17-inch wheel rim.

When choosing the right tires for your vehicle, understanding the speed rating is crucial. But what exactly is a speed rating, and why does it matter?What is a Tire Speed Rating?
A tire's speed rating indicates the maximum speed a tire can safely sustain over time. It's a manufacturer's assurance of tire performance, marked by a letter on the tire's sidewall. This rating is determined under controlled laboratory conditions and is part of a broader standard established by industry entities like the European Tyre and Rim Technical Organisation (ETRTO) and the U.S. Department of Transportation.Common Speed Ratings Explained
- P-Rated: Up to 94 mph - Suitable for smaller sedans or light-duty vehicles.
- Q-Rated: Up to 100 mph - Often found on SUVs and light trucks with consistent highway use.
- R-Rated: Up to 106 mph - Typically for medium-duty trucks and vans.
- S-Rated: Up to 112 mph - Common for family sedans and larger vehicles with moderate performance.
- T-Rated: Up to 118 mph - Optimal for family vehicles, including minivans and some coupes.
Why is the Speed Rating Important?
The speed rating is not just about how fast you can legally drive; it's about safety and performance:- Ensures Safety: It guarantees that the tire can handle certain speeds without overheating and failing, which can prevent blowouts.
- Optimizes Performance: Higher ratings often indicate better handling characteristics, important for maintaining vehicle stability.
- Legal and Insurance Considerations: Matching the speed rating suggested by your vehicle manufacturer can be essential for insurance and warranty purposes.
