the knuckle headed installer severely overtightened the lug nuts and has warped the brake rotors they can be machined flat again if they are thick enough and tell knuckle head that torque sticks [a torque limiting device for impact wrenches] have been available for more than 20 yrs. and to get the 80 ft.lb. one, color code light blue.

The brakes pulsating is only caused by bent rotors. The question you need answered is; how and when did they become bent?
If they were pulsating before you took it in for tires then you need a brake job.
If it only started after the tire installation there is a chance that the Mechanic used an impact wrench that was set too heavy for your vehicle. If an impact wrench is used improperly the massive torque can warp the rotors causing a pulsating brake pedal.
It is very tough to get a repair shop to admit to this.

Did they pulsate before? If not then when the tires were bolted back on the vehicle they probably didn't tighten the bolts in the correct sequence or over torqued them. This is more prone to happen on disc brakes than drums brakes. The fix is to turn the rotors and put in new brake pads. Notice I said AND new pads Do not put old pads on new or freshly turned rotors or you will end up with the same problem. Make sure they use a torque wrench ro tighten the lug nuts and go back 50-100 miles later and heve them checked again. Any reputable shop should be doing this anyway but it doesnt hurt to ask to make sure.

If your brakes are pulsating, it likely has nothing to do with your new tires. Chances are, your brake rotors are warped and you are in need of a brake job. Your rotors either need to be "turned", which means a small amount of metal is shaved off the rotor to make it uniform and smooth, or they may need replacement if they are too far gone. The new tires just may have made this existing problem more noticeable.

Did you have your tires spin balanced. Also could need a front end alignment if this happened just after having tires installed. Did they tell you that you need new brakes. Usually when you get new tires, the shop does a general look at the brakes.

if the pulsation occurs when the brakes are applied then possible you have warp rotors...but if the pulsation is rotational (occurs when the wheel is rotating all the time) the tires probably were not balanced, bent rim or your definition of new tires are used tires.....not really NEW NEW tires
