only thing with brakes was to straighten out the metal lines to adjust for new brackets. while your dealer is correct, in theory, he is wrong. Yes the larger tires have a larger mass and rolling resistance, but its not much different than adding weight. To get larger brakes you would need larger rotors, and also larger rims. i am running 17 inch rims and have no problem stopping.

a POSSIBLE upgrade may just be better brakes than stock.

the only way that i can see to recalibrate the speedometer is to either get a speedometer re calibrator ($300) or a tuner ($350), OR to replace your gears to compensate

 

Thanks for the tips. BTW, your truck looks great! How much was your mileage affected by the lift and tires?

 

Not sure what the stock specs are on our trucks but what you got there is not so good...even without stock specs I can tell you somethings wrong with those numbers.

Lifted trucks should be aligned to the stock specs.

Tell your technician that and have him re-set it to factory specs.

Let me know how it goes...
