CSV, I'm running the 295/70/17's and yes you'll need to recalibrate other you'll have all sorts of problems with ESC kicking in - ask me how I know. Depending on your engine and gearing you'll notice a hit to performance as well. I've got the 3.8L auto with 4.10 ratios and I noticed a big hit to power, especially with long winding uphill sections of the highway.

This was my concern... I've got a 3.6L auto with 3.56 gears hahah. This is goin to be expensive if I want it right... I was hoping 4.10 gears would do it though... Have u upgraded ur Dana axles?

Still running the stock D30 and no problems yet touch wood, but the tyres have only been on a short while. The 3.6 along with the 5-speed will help a lot compared to the 3.8 and 4-speed slush box. I wouldn't be too worried.

3.56 gears? Should be 3.21. Even still the 5 speed Merc auto box of the 2012 onwards has a much better first gear ratio than the old CRD 5 speed or the old petrol 4 speed.

Would that be 3.73? Since it's an auto.
