What is the maximum tire ground speed?

• A. 195 kts
• B. 205 kts
• C. 180 kts
• D. 210 kts

Answer: (A)

Tire ground speed is limited by the tire’s speed rating—the maximum rotation speed the tire can safely handle while rolling on the surface. This rating comes from the tire design and is published in the aircraft’s performance data. For this airplane, the published maximum tire ground speed is 195 knots, so you should not exceed that on taxi, takeoff rollout, or landing rollout. Values higher than 195 would push the tire beyond its rated limit and risk failure, while a lower value would still be safe but isn’t the maximum. Therefore, 195 knots is the true upper limit on the ground.
