The offset of a wheel is the distance from the mounting surface of the wheel to the true centerline of the rim. A positive offset means the mounting surface of the wheel is positioned in front of the true centerline of the rim / tire assembly. This in effect brings the tire in to the fender well more. Conversely, a negative offset means the mounting surface of the wheel is behind the true centerline of the rim / tire assembly. This will cause the tire to stick out away from the vehicle

You can compare the effects of changing the offset and width of your wheels by using a Wheel Offset Calculator

Why Rotate Your Tires?

techcenter-tirerotateThe front tires of your car will wear much more quickly than the rears. Not only that, but the right front tire might tend to wear out more quickly than the left front because the nature of American traffic means that left-hand turns (which load the right-front tire) tend to be taken at higher speeds, and under higher loads, than right-hand turns (which load the left-front tire). And, right-side tires are more likely to be faced with road hazards and hitting curbs. The result of all this is tires wearing out at different rates.

How To Measure Tire Thread Wear


  1. Take a penny and pinch between your thumb and forefinger.
  2. Put Queen Elizabeth II’s Crown into one of the grooves on the tread. Select a point on your tire where tread appears the lowest.
  3. If you can see the top of Queen Elizabeth II’s Crown, the treads are worn and need replacing.

Why Should I Put On Winter Tires?


All Season Tire

  1. Harder rubber, best grip on dry or wet road surfaces.
  2. Performs best at temperatures above 5c: loses traction and grip under -5c.
  3. In very cold waether, loses elasticity, causing adangerous accumulation of snow in the treads.
  4. On compacted snow and frozen road surfaces, longer braking distance than a winter tire.

Winter Tire

  1. Softer rubber, so it’s more flexible in snow and grips more in cold temperatures; performs well up to -40c.
  2. Tread is 10% thicker than on an all-season tire.
  3. More agressive footprint (30% more grooves), which assures greater traction and quicker ejection of snow and slush.
  4. Reduced braking distance by up tp 25% compared to an all-season tire.
