Are you a 2012? I am not and I drive fine and accelerate fine on surface streets. When you notice the underperformance is highway driving, trying to pass or driving on hilly highways. The Jeep struggles to stay at speed. If you are a 2012 w/ the 3.6L, it is doable since there is the more powerful engine and new transmission combo Chrysler put in there.
As for the measurment of the KM2, there are well documented cases of the 35's actuall measuring just over 33" mounted. Make sure you arent over inflated on them. Most all tires come in under their stated size but some are worse than others.
