Why it matters: If this were to occur, power steering assist would be lost and increased steering effort would be required. On vehicles equipped with hydro-boost power brakes, it could also result in loss of power brake assist and increased braking effort would be required. If the power steering fluid spray were…

In addition, the label May also be missing the tire load rating on the label. Although this information is not required by the standard, if a…
Why it matters: If a customer replaces a wheel and only relies on the rim size designation that is indicated on the label, a wheel that is of a different rim contour designation May be installed. It May be difficult or impossible to mount the tire on a wheel with the wrong contour. If the tire is mounted on the…
