PLEASE NOTE---When it comes to going by tire sizes, these tractors are 35 years old, a lot can happen to them in that time.  Also if a customer wanted a different tire size the dealer could have either switched tires from tractors in his stock or ordered and installed different tires.  So if your tractor does not have the "correct" tire size, do not get alarmed, as this only shows how it left the factory.  Thanks.
