I've seen this done at my local dealer and my truck is in an was wondering what was all involved i mounting up the big rubber?My new truck is the 6.5 box Crew with 5.4 3.73 LS rear end 4x4 and the XTR package with the 18" polisehed rims.I know that the stock 18" rims work I was wondering about recalibration for shift points and correct speedometer and the 2" leveling on the front.Also any input on how they drive compared to the stock rubber ie: handling ,gas mileage,tire wear.
Thanks for replying Ryan

 

OK, I'll advise here: just do a search for these items on this forum.. there is so much info on your various topics that it will make your head spin!

I will answer your calibration question though.. you will need to buy a tuner to correct speedo and adjust shift points. The MPG question is just obvious.. its gonna drop with those huge tires.
