Firefighters from Las Vegas and North Las Vegas joined forces Wednesday morning to battle a blaze at an auto service shop on Las Vegas Boulevard North near Carey Avenue. Crews responded just after 1 a.m. to a fire at Sinaloa Tires, 2403 Las Vegas Blvd. North. About 15 units responded. No injuries were reported. North Las Vegas Fire Department Capt Joe Calhoun said crews saw heavy smoke coming from a garage. When they opened the garage door, crews found debris piled to the ceiling. Fire crews had considered calling for a bulldozer to clear the debris, which included dozens of fenders and tires.
