JConcepts has released a newly designed t-shirt based on the popular JC Racing tires theme. This new t-shirt sports a completely detailed front logo design including the popular JConcepts.net along with graffiti type ‘Racing Tires’ font. The image is based around the Dirt Nitro Challenge championship tire, the Metrix. The back of the shirt includes an even larger version of the front print identifying the elements that go into a successful race tire line. The shirts are made of a heavy-duty 50/50 Cotton/Polyester blend and are available in the usual range of sizes.
