Not always, a warped rotor can cause vibration while driving. I used to think this as well, but I had a nasty shake in my '88 GT-S. I put new tires on it (they were worn anyway, I was just looking for an excuse to replace them) and had the wheels balanced. Didnt cure the problem, after awhile it got worse and I started noticing some vibration under braking, however it was hard to distinguish if it was worse under braking because it seemed to shake constantly while cruising. My Tie Rods were fine, and I usually always replace ball joints when I buy a car if the boots are ripped, a good habit to get into.
(Also on the GT-S I ruled out the axles as they had been replaced somewhat recently, the boots arent torn, and they werent making any noise)
I replaced both front rotors and it cured the problem. My MR2 had the same problem, and I even replaced the rack bushings as stated before I even tried the rotors.
