Rear Shimmy

So logic tells me this isn't a problem but maybe, just maybe it is. Daughter's 1995 lumina has a terrible sway in the bag at low speeds. All four wheel are balanced. But I noticed in the back one is a 205 and one's a 215. So there is a slight height difference.

Being front wheel drive and the rear being IRS and no ABS. would that slight difference in size make this thing sway?

Logic tells me that it's a trailing system, so no power is being delivered to it. It's IRS so it should independently keep tire in the proper place. Compensating for that 1/2 inch should be par for the coarse.
