The mud tires are Q rated, and only certified up to 99 mph. That's why the Rubicons and Mojaves are limited at 97. The tires have a top speed rating of 99. You don't want to go faster than that, because it'd be dangerous. Too much heat. All tires have a speed rating. The S rated tires on other gladiators have a speed rating of 112, so those gladiators top out at 110.My JTR has MT's and rides really well at "highway speed" on the interstate (not the river bed). However, its not fun to be passed by a GMC pickup.
You don't want to drive faster than your tires' speed rating, or bad things could happen, quickly. Some Rubis and Mojaves come with S rated AT tires, but they took the lowest rating for them.
Even on sports cars, you'll always find that the limiter is set below the max speed of the OE tires, unless the tires are rated beyond the capability of the vehicle.
