rotated tires now have a shimmy, road force them, fail, got 2 new tires, still a shimmy, rotate tires shimmy gone, The bleeding continues, front end shimmy stopped when the back tires got placed on the front. Logic says it was those 2 new tires, so replaced, put them on the front, shimmies back, balanced multiple times, one guy says good, next guy says their out. Shop replaced all 4 tires with cooper tires,2 tires needed excess weight off they go, got a wheel alignment, and now worse than before, shakes everywhere and pulls to one side. Any recommendations in Edm Alberta canada area. Tire shop has the elite hunter machine telling me 20lbs is normal, oh what a headache.
