I am awaiting the delivery of my 392 and I am looking to do the same as you are doing with switching the tires before delivery, with the dealer doing it they are also say that they are willing to do the speedometer recalibration, I`m not sure if that will really happen or will I have to go the Tazer or other reprogrammer. What tires did you decide go with? Actual 35"s E range or the 315/70/17 C range identical to what came stock on my Raptor? Thanks for the updates and please keep them coming. I am really looking forward to getting mine whenever it gets hereLooks great. Living through you for the time being till mine gets delivered.
As for the 33s vs 35s its all about the CAFE standards. Jeep will take a hit with their average CAFE rating and even squeezing one more MPG out of it by putting 33s on it helps. Anyone who buys this could care less about MPG. More about the fun factor. Ive had a TrackHawk for 2 years now and I smile every time I hit the gas. I'm sure this will have the same effect on my facial muscles. I'm thankful they finally put a V8 in hit and I've already made arrangements to put 35s on it before I take delivery.
