What is the maximum tire ground speed?

• A. 182 kts
• B. 170 kts
• C. 180 kts
• D. 186 kts

Answer: (A)

The main idea here is that tires have a speed rating, and the maximum tire ground speed is the highest speed at which the tires are allowed to roll on the ground. This limit comes from the tire design and is published in the aircraft’s limitations. Exceeding it increases the risk of tire failure due to centrifugal stress, heat, or tread damage during taxi, takeoff roll, or landing roll. For this item, the documented tire ground speed limit is 182 knots, so that value is the correct choice. The other numbers don’t match the published limit and either understate the allowed speed or risk exceeding the tire’s rating.
