Tire and Wheel Info
38×14.50 tire on standard offset wheel
IMPORTANT DISCLAIMER: The provided tire/wheel fitments are approximate.
Actual dimensions of a given tire size can vary considerably from one brand to another.
Manufacturers’ wheel offset and backspacing measurement points are not always consistent.
Backspacing greatly impacts tire-to-fender clearance when turning.
Wheel width and backspacing influence whether the tires protrude past the fenders, and to what extent.
Considering these important factors, we recommend that you fit-check your tire/wheel selection prior to purchasing.
1977.5-91 models require clearancing (machining) of the front driveshaft CV cluster to prevent binding. If vehicle has single exhaust, the cross-over pipe requires modification to clear front driveshaft.
Optional extended length brake hoses recommended.
