The Annual Pit Bull Tires Mud Bash - is held the 3rd Saturday in October each year…60 miles South of St. Louis, in Bloomsdale, Missouri at Custom-Differentials’ location. The weather is always nice and the mud is always slinging on the 3 mud runs. There are usually 5,000 attendees who come to live large and Tear It Up.

The Rock Crawl course is always changing and is put to good use for Rock Races rather than traditional Rock Crawls.
Truck Pulls are held and the first place winner gets a free set of 35” Pit Bull Rockers.
Pit Bull gives away a set of 33” tires to one lucky attendee every year.
And yes, there is usually a Bikini contest which is always great fun for the contestants and on-lookers.
