If vehicle has duals, read dual capacity from tire and multiply by 2 to obtain dual assembly load capacity. THE EFFECT OF TOWED VEHICLES OR TRAILERS If your RV is towing a vehicle, you need to know the RV’s GCWR (Gross Combined Weight Rating), the total actual loaded weight of the RV, plus the total actual loaded weight of the towed vehicle. Even though the GCWR has more to do with the design limits of the drivetrain (engine, transmission, axle, brakes, and bearings), the additional weight can also affect the tires and the RV’s handling. Also, always remember to consider the tongue weight of the trailer and its effect on handling. 76 Section Five: MICHELIN RV Tires ®
