What 245/40R17 tires means
The 245/40R17 size code is a precise description of the tire's shape. The first number, 245, is the section width in millimeters (about 9.65 inches) measured across the widest part of the tire. The 40 is the aspect ratio, meaning the sidewall height is 40% of the section width, which works out to roughly 98 mm (3.86 inches) tall. The R17 indicates a radial construction built for a 17-inch wheel diameter.
Put together, these numbers produce an overall tire diameter of about 24.72 inches and roughly 816 revolutions per mile. Those figures matter to you as a buyer: a shorter sidewall in the low-profile 40-series delivers crisp steering response but leaves less cushion over bumps, while matching the correct overall diameter keeps your speedometer and odometer readings accurate. Staying within this size range also protects fender and suspension clearance.
Vehicles & uses
A relatively wide, low-profile size like 245/40R17 is commonly found on performance-oriented cars and sport sedans where handling and cornering response are priorities. Shoppers choosing this size typically want stability at speed and a planted feel through corners rather than maximum ride comfort. Because exact fitment depends on your specific vehicle, always confirm the size against your door placard or owner's manual before ordering.

How to choose
Season
Decide first on the season rating. Summer tires maximize dry and wet grip in warm weather, all-season tires balance year-round usability, and winter tires are engineered for cold, snow, and ice. Many 245/40R17 options are all-season, but summer performance choices are available too.
Treadwear & UTQG
The UTQG treadwear grade helps you compare expected tread life within a brand's range: higher numbers generally suggest longer wear, while grippier performance compounds often carry lower numbers. Check the mileage warranty offered with each model as well.
Load index & speed rating
The load index and speed rating (the numbers and letter after the size) must meet or exceed your vehicle's requirements. Match these to your original equipment specification to keep handling and safety consistent.
