What is the maximum tire ground speed?

• A. 185kt
• B. 195kt
• C. 200kt
• D. 190kt

Answer: (B)

Tires on an aircraft have a maximum ground speed rating, which is the highest surface speed the tire can safely rotate on the runway. This rating is set by the tire’s construction and testing to prevent excessive heat buildup that could lead to tire damage or failure during taxiing, takeoff roll, or landing rollout. The widely used value for this limit is 195 knots, so that’s why 195 knots is the best choice. It’s a ground-speed constraint tied to the tire itself, not the aircraft’s airspeed limits. Other numbers like 185, 190, or 200 knots aren’t the standard tire-ground-speed rating used in typical ops.
