Frequently Asked Questions
The major difference is the diameter ratio – the side wall of a 225/65R16 tire is 65 percent tall as compared to the shorter 60 percent wall of a 225/60R16 tire. Therefore, when fitted on the same 16-inch wheel, the 225/65R16 tire has a larger overall diameter and is taller.
On this tire size, 225 is the tread width in millimeters, while 65 is the aspect ratio. The aspect ratio is the ratio of the percent of the sidewall height to the tread width. R refers to the radial construction and 16 represents the wheel diameter in inches.
When correctly mounted on a 16-inch wheel and inflated to 35 psi to hold the tire up, this tire size requires 27.6 inches in overall diameter. Its tread width is 8.9 inches, including a sidewall height of 7.2 inches due to a 65% aspect ratio.
These tires typically have a lead index/speed rating of 98H (1653 lbs max load, 130 mph max speed), 101H (1819 lbs, 130 mph), or 101T (1819 lbs, 118 mph). Make sure to check which index/speed matches your vehicle.
This tire size suits a broad range of vehicles. Some sedans, like the Toyota Camry, Honda Accord, and Nissan Altima. Crossovers, such as the Ford Escape, Toyota RAV4, and Subaru Outback. And minivans, such as the Chrysler Pacifica.
