My '94 E320 wagon wobbles a little in the front end below 45 mph when beginning to drive. It either settles out or I become used it. I think the chances of the cause being suspension related is low so my question is about the tires. I am running stock size Bridgestone Potenza 950 with about 10,000 miles on them properly rotated. Pressure is always about 35 psi front and rear. Do they get a 'flat spot' while resting even in fairly warm weather and then smooth out after a while?
