What Size tire on a 1998 Chev blazer 4X4 factory?

Answer:
there are two factory tire sizes for that truck. a 235/70R15 was standard, while a 235/75R15 was optional.
you would need to have your VIN ran to find out which one your truck was built with.
there is almost an inch difference in diameter between the sizes, and can result in a little over 3% speedo error (aprox 2MPH @ 60MPH)
