Tire Marks: Why Are They on My New Garage Floor?

tire marks garage floorHave you ever wondered why you find tire marks on your new garage floor?

In the late 1940’s Michelin tire started to develop a replacement material to the natural rubber being used in the manufacturing process of the automotive tire.  By 1968 almost 80% of all automotive tires had some concentrate of SBR (styrene-butadiene). This co-polymer was designed for better traction of the tire to various road surfaces. Today 100% of all automotive tires have a high level of SBR. This solvent based plasticizer through centrifugal force works its way to the perimeter of your tire. When your tire travels, it creates heat, along with warm or hot pavement the temperatures can be well over 100 degrees.

When you pull your car into your garage, these 4 hot tires come in contact with a cooler surface (your concrete or coated surface). During the initial contact and throughout the cool down phase this solvent softens most top coats. This causes in many cases, the previously coated surface to “grab” on or attach itself to the tire tread pattern. When you back out of your garage your inferior coating comes with your tires, or leaves “paw prints”.

However, NOT with MuscleGloss! We have top coats tested against the latest chemical compositions of SBR, and so far we have not had one claim of “paw prints” or tire marks on our top coats!
