the girl that ive been kinda seeing just bought a 03 marauder w/ 35k on it . it has a few bugs but all easy fixes , be sides the traction control keeps activating , the car does have all the same size tires, and the dealer is putting the correct rear tires on before we pic it up and fixing the head lights for her . will the correct tires fix the traction control problem or it there something else wrong ???
