Anthony,
Excess tire rubbing on the rear of the wheel housing for the front wheels was an issue with some of the SMC (Magnum chassis) built Patriots. If the Tire rubs on the front of the wheel housing, the wheel housing can be moved, but since the air bag is directly behind the rear of the wheel housing, excessive rubbing is difficult to correct. On some of the early Patriot coaches with a Magnum chassis, tire size needed to be increased because of overloading, and on those coaches, SMC printed out detailed instructions on how to move the front axle forward enough to clear the larger tires to prevent air bag damage.
