Give Size My Tires a Facebook Like and Win $100

Size My Tires is an interactive tool to help users find the original tire size for their vehicle. Since launching last year, more than 500 users have "liked" us on Facebook and nearly 50 Google Plus users have done the same.

To celebrate our modest success with social media, we are giving away a $100 prize to the person behind the 1,000th Facebook like.

Why do people like Size My Tires? First, the tool on the front page of the website works very quickly. Written in jQuery, it looks up a vehicle's tire size in five quick steps without re-loading the page. Just select your 1) make, 2) year, 3) model, and 4) options, and you'll discover your 5) tire size in less than 30 seconds.

If you want more information about your vehicle's tire size, just click on the link in the final step. You'll see a color-coded tire code with an explanation behind each color. With the help of a tire code broken down by color, you can easily determine the width, recommended rim size, speed rating, etc. for your vehicle.
