These tires were very smooth and quiet when they were new. We have about 20,000 miles now on this set and they have terrible wear patterns developing. Bad cupping and irregular wear from inside to the outside. The vehicle is not at fault. I have personally aligned the car 3 times since installation of these tires and they continue to wear in strange ways. The very inside edge is almost to the wear bars as is the outer 2/3 of the tread yet the second to the innermost tread blocks have at least 6/32 of an inch left. Almost as if that section of the tire is a much harder compound than the rest of the tread. This results in a very nervous handling car that follows every groove imaginable. Our previous set of Hankook tires wore down perfectly even and tracked just fine. I've had three sets of Cooper tires on other cars and they were great but these are very disappointing. Definitely not worth the money.
Purchased in Spring 2014 after my worthless Kumho factory-installed ones had zero grip in the snow. They perform very well on wet and dry surfaces and are surprisingly good in the snow. Falken added a substance to the 950s for longer life because the 912s would wear out too soon. Great tread life, good grip in all weather, all at an unbeatable price. What more could you ask for?
I bought this tire for my turbo Sonata because they can be rotated across all 4 weeks, being asymmetrical. I was concerned about premature tire wear. Treadwear has actually been fine after 25k miles. Noise is average for a performance-oriented tire, but my winter tires are definitely noisier. The other thing I liked is that they can handle a light winter storm.
They were a downgrade from my summer Falkens FK452 in dry handling. They feel "floatier" than those tires and they do not handle quite as well either. Still, dry handling is FAR better than the junk stock optimo's the car came with. They do not tramline like my Falkens did, though.
They are not very good in wet and have poor resistance to hydroplaning. They break free constantly at highway speeds and I am very afraid of hydroplaning. I'm at 50% tire life and they sometimes scare me. They are especially bad approaching freezing temps, when they can't get up to temp. During run of the mill rainstorms, cars fly by me but I'm struggling to keep the sonata on the road at 55.
If anyone is wondering how they are in snow- I got caught in an early season snowstorm. They will be safe up to 2in of snow and that's it. Starting uphill is toughest, but once you get going you can generally maintain from there. Still this is an emergency-only winter tire. I haven't got caught in ice yet with this tire (thank god!).
Overall I would probably buy again. It's hard to find asymmetrical sport tires like this.
I live in Denver and grew up in Iowa and Michigan so I am a pro at driving in snow. The OEM Sonata tires were a joke, designed to inflate the MPG ratings for Hyundai. They were dangerous except on dry roads but they got amazing MPG. The Hankooks were the opposite. The first winter the snow traction was incredible, based on the more aggressive and varied siping but I lost about 3 MPG. Tires sounded a little more like snow tires than all season. Great traction in snow and road noise tend to go hand in hand because the tread is more aggressive. This is my 2nd winter and traction is still very good in snow. They would be better but they are inflated higher than normal because I now have NitroFil (nitrogen in my tires) so I get a softer ride even with higher tire pressure. It does effect the traction negatively as you might suspect but my tire wear is negligible this way. So far these are great tires but if you look at some of the reviews, I am noticing that owners of light weight vehicles are not impressed. Look at the advertising by Hankook and that makes sense. "Luxury sedans" may indicate a heavier car and the tire may do better with some weight. Personally, my lighter weight cars always got Michelin tires because one of their characteristics always used to be softer sidewalls which meant even a light weight car would depress the tire and you would get a softer ride. Not sure that is still true today but it was for 30 years or so.
Former GM cold weather test driver now living in Edmonton, Alberta. I drive like I was trained to drive, with these tires on a FWD Hyundai, light car and live on a seldom plowed street, parking in the back. No problem at all getting through moderate light snow (6 to 8 inches) and on the icy streets, they did not often get sucked into ice ruts. On flat icy roads, they handle almost like summer.
Studded, they sound like popcorn, so I just turned the radio volume up a notch. Very stable. Sold the car and after seeing how well they worked, my wife has me selling the Blizzaks on her Elantra and she is taking these over to drive my kids around on. GREAT tires.
Not a bad tire... very good traction in wet and dry conditions. My mileage dropped by about 5%. Started off quiet but became very noisy. After 20k these tires would hum loudly. I had to replace them with Michelins since the Cs4's were unbearably loud. My advice is to spend the extra $$ and get Michelins. They cost more but are definitely worth it.
