"Speed ratings are based on scientific tests where the tyre is run at speeds in 6.2 mph steps in 10 minute increments until the required speed has been met."

"The code is made up of one or two letters, or one letter and one number. It indicates the maximum permitted speed that the tire can sustain for a ten minute endurance without being in danger.[citation needed]"

My Surf does more than that. However I forgot which speed rating my General Grabber A/T's are. I know MT's are Q which is 99mph.

Mine will do 85mph if I'm going downhill with the wind behind me

i did 85mph in mine towing the trailer with a surf on.I was a bit shocked when i looked at the speedo and slowed down again

Even my 2.4 did 90 on flat ground. Come to an incline and the speed dropped though. L200 intercooler, 11psi boost, 2.25" free flowing exhaust.
