Stock tires on 2010-13 Subaru Legacy with 17 alloy wheels are the Turanza EL400-02. They were reasonably acceptable on my 2010 Limited model, however, for 2013, the Legacy's suspension was tightened up to decrease body roll by 40%, resulting in an ultra-stiff & harsh ride except on only the smoothest of roads. The base model with 205/60/16 tires isn't as harsh but the 17 50 series tires on the Premium & Limited models pick up an excessive & unacceptable amt of road feel & roughness. After several trips to the dealer & mucho correspondence with Subaru of America, I decided, at only 3K miles, to take them off and replace them with the new Bridgestone Turanza Serenity Plus tires. The difference was amazing - the vehicle is transformed - I've lost only a minimal amt handling compared to the stock EL400 & the car still handles way better than comparable '13 Altima, Accord, Camry, Sonata & Optima - all of which I test drove, the Serenity Plus tires are not only quieter but most importantly take the edge of the feeling of getting your teeth knocked out at every expansion joint or patch in the road for a smoother more comfortable ride. Never in my 53 years have I ever had a new set of tires in the same size make such a positive and profound difference in a vehicle. If you're unhappy with the ride of your 2013 Legacy - I highly recommend the switch, you won't go wrong. Haven't rated them for snow yet, but wanted to get this up asap in case anyone's been as frustrated as I have been with the 2013 suspension changes. If you have a similar mid-size car like those mentioned previously with low profile tires - my guess is that you'd be even more satisfied with upgrading to the Serenity Plus - as many previous Michelin owners here on this blog have attested to.
