NASCAR teams use 53-ft trailers customized into mobile garages not only to haul race cars and support equipment to and from every event but also to provide a lounge area for drivers and pit crew members alike for rest.
NASCAR teams may use between nine and 14 sets of tires per race; which equates to between 36 and 56 total tires. Multiply by the 43 cars typically competing per race and that can add up to between 1,548 to 2,408 tires overall. By the way, each tire costs $449 each yet lasts only about 100 miles, with teams spending an average of $20,000 on tires for a single race.
During a season, the NASCAR teams travel over 38 weekends across 23 different areas or "markets" within the U.S. and that doesn’t include test driving sessions. Parts and personnel are typically flown in and out of the different racing venues, with trucks hauling the cars and bigger components.
Regular Class 8 highway tractors do the hauling for NASCAR teams. Note the grill being used at the back of the trailer: teams stay on site all race day long and in the main cook their own food.
NASCAR race weekends are broken up into two main events: the Nationwide race on Saturday and Sprint Cup series on Sundays. Nationwide cars are 100 lbs lighter and 300 hp slower than their bigger Sprint Cup brethren. Nationwide teams also cost less to operate, with annual budgets of around $10 million versus $30 million for Sprint Cup teams.
Sunoco provides NASCAR Nationwide cars with an E15 blended fuel; comprised of 15% ethanol blended with 85% 110-octane gasoline. Nationwide cars have to date raced 5 million miles on this blended fuel.
E15 is still highly flammable so great care is taken by the crews assigned to reloading the pit fuel dispensers used by NASCAR teams.
Firefighters are stationed right at NASCAR race refueling depots just in case anything goes wrong.
Trailers are even used to provide mobile registration booths for NASCAR events.
