Which speed corresponds to the maximum tire ground speed in this context?

• A. 195 Knots
• B. 215 Knots
• C. 185 Knots
• D. 205 Knots

Answer: (A)

Tires have a maximum safe speed set by their construction, expressed as tire ground speed. This rating relates to how fast the wheel can turn on the ground without causing excessive heat or structural stress in the tire. Exceeding that rating risks tire failure during taxi, takeoff, or landing. In this scenario, the tire’s maximum ground speed is 195 knots, so speeds of 205 or 215 knots would exceed the tire’s rating and aren’t safe. A speed of 185 knots is below the limit, but it isn’t the maximum safe value. Therefore, 195 knots is the highest speed at which the tire can safely operate in this context.
