Tires must not exceed which rating?

• A. Tire inflation limit
• B. Tire manufacturer's maximum static load rating
• C. GVWR
• D. Recommended load for operation

Answer: (B)

Tire safety hinges on not exceeding the tire’s capacity to carry weight. Each tire is engineered to support a specific maximum static load, a rating published by the tire manufacturer. You must not load a tire beyond that limit, because exceeding it can cause overheating, sidewall failure, or a blowout even if the overall vehicle weight seems acceptable. The vehicle’s GVWR is a general limit for the whole vehicle, not the per-tire capability, so it can be higher than what a single tire can safely carry, which is why the tire’s own rating is the controlling factor when determining allowable loads. The inflation limit governs pressure, which matters for safety and performance too, but it is a different kind of rating than the load a tire can bear. The “recommended load for operation” is guidance rather than a formal maximum; the hard constraint you must respect is the tire’s maximum static load rating.
