no to all of the above...2 season old winter tires, evenly worn, balanced, on brand new factory rims, old rims shot from age....summer tires 4 seasons old, balanced, on quality aftermarket alloy rims, steering wheel only slightly off center, remember Tire Rack personnel telling me the summer setup is slightly smaller in overall diameter than stock stetup...again, no problems, mostly just curiousity on my part...thanks to James and Klaus for their replies...
