What 245/45R17 tires means
The size code breaks down into exact measurements. The 245 is the section width in millimeters (about 9.65 inches). The 45 is the aspect ratio, meaning the sidewall height is 45% of that width — roughly 110.2 mm, or 4.34 inches. The R means radial construction, and 17 is the wheel diameter in inches the tire mounts to.
Add the sidewall on both sides to the rim and you get an overall tire diameter of about 25.68 inches, which turns roughly 785 revolutions per mile. Those numbers matter to you as a buyer: overall diameter drives speedometer accuracy and clearance in the wheel well, while the relatively low-profile 45-series sidewall trades a little ride cushion for sharper steering response.
Vehicles & uses
This is a common fitment class for sporty sedans and coupes, where a wider tread and shorter sidewall support responsive handling. Because it is a mainstream performance size, you'll find everything from grippy summer tires to all-season and even winter compounds. Always confirm the size against your door-jamb placard or the sidewall of your current tires before ordering, since the correct fitment depends on your specific vehicle.

How to choose
Season
Summer tires give the most grip in warm, dry and wet conditions but stiffen in the cold. All-season tires balance year-round usability. Winter tires, such as the Viking Contact 7, are purpose-built for snow and ice.
Treadwear & UTQG
The UTQG treadwear grade helps you compare expected tread life within a brand's line — a higher number generally suggests longer wear, often at some cost to ultimate grip.
Load index & speed rating
Match or exceed the load index and speed rating your vehicle requires; note that several options here carry an XL (extra load) designation. Check the manufacturer's mileage warranty as a final tiebreaker between similar tires.
