Usage on Case/IH Magnum Tractors

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.

Call the Firestone Sales Engineering office at 1-800-847-3364 or your local Case/IH dealer if there are any questions.
