It sounds like the tire or tires are improperly balanced. That is the most likely answer, though it could be other things, too.
you might have run out on your rotors as well as bad balance on your front tires.
Your car probably has abnormally worn in tires, caused by misalignment. Worn rotors can cause this as well.
It could be your rims are bent. Or it could be the rotors are warped
Tires,inner tie rod bushings, if the steering wheel shakes when brakes are applied - brake rotors warped.
prob a broken belt in one of the front tires
You need new rotors or they need to go on this belt at the mechanic that re groves them.
bad rotors
Radial tire may have separated. Take off front tires and look at thread to be sure it does not have a wavy pattern to it. If does, have to replace the tire or tires. If shake when put on brake, rotors are probally out of round and need to be turned. If worn to thin will have to replace rotors.
Bad tires and bad alignment can cause the car to shake at certain speeds.
If a car shakes during acceleration the brake rotors may be damaged. If the rotors are damaged they will be unstable as the tires rotates making the whole car shake.
No,but tires out of balance will cause this. Have them balanced and rotated.
Tire or tires out of balance and when stopping brake drums or rotors out of round or warped
