well, yall could save a bunch of time and headache by just asking techs in the field. while brake performance may not be affected greatly, brake pad and rotor life is shortened. take the stock 16" aluminum wheels off a tahoe and swap them for 22" steelies and watch the pad life be cut in half. some drug dealer at my old GM dealer did this. he was in every 8-10k miles for a front brake job. and he didnt tow anything with it either. i would guess average front brake pad life on those tahoes was about 20k miles, depending on driver habit.
