Don't let the low price of these tires scare you away. They are great; these tires are very quiet with good grip on dry pavement. I haven't had the chance to drive in a down pour yet but so I don't know how well they will do in reducing hydroplaning but I have driven in light rain and they returned great road grip. Light rain is the best judgement for tires as it isn't enough to wash away the oil on the road but enough to lift it up and make the road slippery. So if you are on the fence with these tires just take the plunge because you won't be disappointed.
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.
