20.8R42 R-2 USAGE ON CASE/IH MAGNUM TRACTORS (CAUTION)
F-043-X Date: JULY, 1992 CAUTION Do not use 20.8R42 R-2 tires on Case/IH Magnum tractors. Case/IH engineers have advised of a fitment problem with 20.8R42 R-2 tires on their Magnum tractors. In wet conditions, the build-up of mud on the tire could cause fender damage due to the close tolerance between fender and tire.
