Quick answer

TSB: During the manufacturing process, tires are mounted on the vehicle as matched sets to help reduce conditions such as pulling or drifting. If the wheels are replaced or refinished before vehicle delivery, it is important that the tires remain on the vehicle in the same location and in the same direction of rotation.

What this bulletin may mean before buying

Treat this as service research, not a verdict on one car. Before you buy, compare this communication with official recall campaigns, model-level owner complaint patterns, and the exact vehicle’s VIN-decoded specifications. A bulletin can help you ask a seller or dealer sharper questions about software updates, known repairs, warranty extensions and service history.

Frequently asked questions

What is NHTSA service bulletin 10174877?

How should a used-car buyer use this bulletin?

Use it as a research signal. Compare it with recalls, owner complaints, service records, a VIN report and an independent inspection before buying.
