Priorities for Sizing Winter Tires Are Different

Does your sports car, coupe, or sedan use wide, low profile tires that are mounted on large diameter wheels? Or does your light truck use large flotation-sized tires? If you're going to drive through lots of snow this year you'll want your winter tires and wheels in sizes that help put the laws of physics on your side.

A wide, low profile or large tire has to "plow" a wide path through snow which causes more resistance. The narrower the tire, the easier you can get through snow. We'll help verify sufficient load capacity and the appropriate diameter for your vehicle when you speak with one of our sales specialists or use Winter Shop by Vehicle.

Winter tire sizes should be based on one of the following:
The Optional Tire and Wheel Size from Your Vehicle's Base Model

This is often the easiest way to select an appropriate narrow tire for your car or truck. For example, a 2003 Lexus IS300 would store its original 215/45R17 tires in favor of optional 205/55R16 tires on 16" wheels.
A Minus Size Tire and Wheel

Minus Sizing is simply traditional Plus Sizing techniques used backwards. For example, a 2003 Volkswagen Jetta GLX VR6 would store its original 205/55R16 (or optional 225/45HR17) tires in favor of Minus One or Minus Two size 195/65R15 tires on 15" wheels.

In both of these examples, not only would snow traction be enhanced, but the cost of a Base Model or Minus Size winter tire & wheel package is usually lower than a package maintaining your vehicle's original size tires and wheels.

Winter Tire and Wheel Packages are available for many vehicles. Build one today or select our Preferred Package* for your vehicle.

Since Tire Rack was used by you as a reference maybe you can use this one too.
