Last name: Kiefer. This interesting and unusual surname is of Germanic origin, and is a metonymic occupational name for a maker or repairer of wooden vessels such as barrels, tubs, casks and vats. The derivation is from the German kief(e), kufe, itself coming from the Old High German kuofa, barrel.
Commercial Driver's License (CDL) A CDL is required to drive any of the following vehicles: Any combination of vehicles with a gross combined weight rating (GCWR) of 26,001 or more pounds, providing the gross vehicle weight rating (GVWR) of the vehicle being towed is in excess of 10,000 pounds.
This is the equivalent of dividing the tireâs sidewall branded load capacity by 1.10. For example, a P265/75R16 114S tire has a maximum load rating of 2,601 lbs. at 35 psi. However, when this tire is installed on a light truck, the load rating is reduced by a factor of 1.10 to 2,365 lbs.
