Can and will dealer make adjustments for larger tire sizes?

I plan to have the dealer mount, balance, install and align my new wheels and tires. I'll be going from the stock 32" Sahara wheels/tires to 33" LT285/70R17. Will the dealer be able to reset/calibrate and make the necessary changes to account for the larger tires? or will i have to get a Procal? Will the dealer reset the TPMS system to my preference? I'm getting closer. My new Sahara is supposed to be at the dealer Monday.
2014 2 Door Sahara, Granite, 3.73, 17x9 BirdDog Wheels, 33" Goodyear Silent Armors. Teraflex Leveling Kit, Hanson or Hyline Bumpers, etc. coming soon.

They not only can but my dealer recommended using them for it if I change tire size to avoid warranty issues. Some dealers will try to void engine warranties if you recal yourself with a procal or similar device. My dealer said it was like $90

Some dealers will recalibrate the tire size for free.....My dealer charged me $15. But they all can do it.
As for recalibrating the TPMS....I can't tell if they'll do it or not. In some states it's considered "tampering" with a safety device. It's just a question of doing something legal or not. I think if you have a Procal, you can do it yourself.

This got me thinking. I upgraded my stock 16 wheels to the rubi take offs. I bought the procal and calibrated accordingly. I will be taking my jeep in to have the auto tranny looked at because of continued weird shifting mostly 1 and 2 gears. I will be reprogramming everything back to stock prior to taking it in.

I have a slight concern as the dealership might blame the rubi wheels for my tranny shifts being off. I can't tell them that I used a procal and it still sucked, so do I play stupid? I've owned two TJ's and find it hard to believe that some rubi wheels would grant them the ability to use that excuse. Especially when people are running much larger wheels than me.
