These are the second set on my current car. The first set lasted only 25000 Km and were replaced on an optional protection plan when they were branded "defective". During the first 20000 Km they performed very well in all categories, most notably snowy conditions. For the next 5000km they were noisy and very difficult to balance. An alignment in the last 2000 km was ineffective. Concurrent to replacing, I changed out the shocks, struts and completed an alignment. So far they feel great, quiet and vibration free. After 50000 Km I'll submit a new review.
