I recently picked up an A4 Quattro with badly cupped tires (noise above 40 kph, vibration when braking at high speeds). While I'm planning on getting an alignment done, I'm not sure when the best time would be to get it, or whether or not it even makes a difference: - Now, with the cupped all-seasons on OEM alloy rims. - Next week, when I put on new winters on steel rims. - Next Spring, when the cupped tires are replaced. Would I need multiple alignments?
