Frequently Asked Questions
It is the tire size information. 255 is the width of the tire’s tread in millimeters. 45 equals the aspect ratio and measures the height of the sidewall as a percentage of the tread 45% of 255 mm equals 114.75 mm. R is associated with radial construction. 17 shows the diameter of the wheel rim in inches.
255/45R17 tires can be found on a range of automobiles, including sports sedans, performance coupes, and performance-oriented SUVs and crossovers. The BMW 3 Series, Audi A4, Nissan Maxima, Ford Mustang, and the majority of medium-sized SUVs are all great tire choices.
Consider replacing your 255/45R17 tires every 6 years, regardless of tread depth, since the tire compound can degrade with time. When the tread depth is below 2/32 of an inch or there is evidence of more wear, cracks, bulging, or other defects, other manifestations of damage are evident. Tire rotation and regular inspections can help maximize tire life.
Although 255/45R17 tires are suitable for multiple driving environments, they may not be the ideal option for an extreme winter. To promote maximum traction in snow and ice, it is recommended to pick between winter or all-weather rubber with the respective tread patterns and tire compounds. For the majority of high-performance summer tire models, driving in the wet, during cold temperatures, and on ice patches may prove to be quite difficult.
A 255 45R17 tire is 10.0 inches wide at the tread. It is approximately 4.5 inches from the wheel to the tread. Moreover, it has an overall diameter of about 25.9 inches on a 17-inch wheel rim. These dimensions strike a balance between tread width and sidewall height and are ideal for many performance-focused cars.
