Does anyone know what the is widest tire size that will fit on to the stock rim of a 2002 eldorado? I've seen street/truck tires in the size of 255/55/16 but don't know if they would be too wide for my stock rim or how they would handle. I also have seen 245/55/16 but they were summer only tires and I live in the midwest snowbelt and drive the car year round. I want a lower profile, wider, better handling all season tire.
