Frequently Asked Questions
This information refers to the tire’s dimensions and characteristics. In this case, 215 is the width of the tire in millimeters, 65 is the aspect ratio, or the percent of width between the road and the edge. R is a construction method in the form of a radial, and 17 is the diameter of the studs.
The tread width is the key difference between these tire sizes. As for the similarities, both sizes have the same rim diameter of 17 inches, while the proportion of the sidewall height to the tread width is 65%. However, the tread width is 225 millimeters on a 225/65R17 tire and 215 millimeters on a 215/65R17 tire.
A 215/65R17 has an overall height or diameter ranging from about 28.5 inches to 724 millimeters. This is determined with the help of tread width, 65% of which is the height of the sidewall, and the 17” diameter of the rim. The larger overall diameter of this size plays an integral part in increasing the ground clearance and off-road suitability of the size for SUVs and light trucks.
Yes, they are suitable for all-season tires. They behave perfectly on the road in all weather conditions. These tires work best on dry, wet, and light snowy roads as they offer great traction.
215/65R17 tires strike a balance between fuel consumption and traction, making them favorable for regular driving. The width is narrower which results in less rolling resistance meaning that the car will use less gas. However, the aspect ratio of 65 increases the sidewall’s height which increases traction on rough roads and negatively affects fuel economy.
