Experts say that you must check your tire pressure at least once a month and before going on a long trip.For tires manufactured prior to the year 2000, three numbers instead of four indicate the date of manufacture.Also, during the early 1990’s, Continental added a triangle (◄) to the end of the character string to distinguish a tire built in the 1990’s from previous decades (e.g., a tire with the information "DOT XXXXXXX274◄” was manufactured in the 27th week of 1994).
