Thanks for that feedback on the Pure Contacts. I think I've narrowed it down to either the Pure Contacts or the Serenity Plus for when I do finally get rid of the Michelin Energy Savers.
I read most of the reviews for both of them on Tire Rack, and it seems the Pure Contacts are reviewed a bit better. My two priorities are noise level and ride comfort. If you look at their tread patterns, both of them have some funky designs going on in the middle area of the tread area, so that could be the source of a bit of tread noise.
Update:
Well, back in 2013, I went with a set of Michelin Premier A/S, although they didn't come in the exact OE size. Part of the reason I went with them was the great reviews on Tire Rack. I don't like the fact that Michelin is trying what IMO is a gimmick with this business of only providing 8/32" of tread depth. However, the tires rode pretty well and were fairly quiet.
Recently, although the Premier A/S still had some tread depth left, my wife expressed concern that the car was squirrely on wet roads(she is the primary driver of the Genesis now). I again checked reviews on Tire Rack and found that Michelin has come out with the Premier LTX, which is billed as a SUV Grand Touring tire. (I have a set of Pirelli Cinturato P7 on my 2012
Buick LaCrosse and, although they are quiet on a perfectly smooth and quiet surface, they are pretty noisy on any sort of coarse surface, and you also feel most any surface irregularities. So, I had ruled out the P7 for the Genesis.) A number of the Premier LTX reviews were from people who had driven on both the Premier A/S and the new Premier LTX, some of whom loved the LTX so much that they didn't even know why Michelin even still sold the A/S. Overall, the reviews indicated that the Premier LTX were the quietest tires they had driven on. As noise comfort is one of my top considerations, I wanted to try a set. The reviews also indicated that the LTX were the best for ride comfort. I would have tried a set of Bridgestone Ecopia, but I don't think they were not available in that size.
I was pleased to find that the Premier LTX was available in my OE tire size. Now, Michelin is still going with the shallow, 8/32" tread depth, but since my wife's commute to work is so short, I figured the tires would last a long time. Upon physical examination of a set of LTX, I did indeed notice immediately that the rubber compound was comparatively(to other tires) malleable and what I was looking for.
So, with Discount Tire's 30-day test drive feature in mind, I bought a set of the Premier LTX. I figured that, even though they bill it as a SUV tire, the Genesis pushes 4,000 pounds and they might work out fine. The new Premier LTX were immediately more supple riding and quiet than the Premier A/S, even when the A/S were new. The soft compound of the LTX just eat up small irregularities on the road. They are very quiet overall, although there is a bit of tread pattern noise. I think it is an acceptable slight amount of noise that is necessary in order for them to achieve the wet performance they get out of them. Overall, a great set of tires, unless you're looking more for a performance tire.
