Purchased a set just before driving from Toronto to Florida and back. Based on the other reviews and a good sale price, they seemed like the right choice. This review is strictly based on the 3300 miles driven over a 2 week period.
Weather / Traction
We covered three seasons during this drive. Light snow/slush/rain going through the Poconos and New York State in both directions; and, fall turning to summer conditions as we went from the Carolinas into Florida. It felt like very solid dry pavement driving, even in the snow and the rain. I held back from giving them a 10 in a few cases only because the conditions weren't extreme enough to see how they would do when really pushed.
If you have read the literature, you know that tires are based on a lot of tradeoffs. You don't get the highest mileage on tires that provide really good grip. I keep my tires pumped pretty hard (37 psi in this case) and that helps the mileage a bit. I ended up with 35.8 mpg on this trip which is about average for this car. Driving at 80 mph on many long stretches (with a heavily loaded car) isn't consistent with great gas mileage. On a previous trip to Florida (with fairly new Sailun tires), I got closer to 40 mpg but that was on a different route with slower average speeds.
I like how they ride. Especially with the higher psi, you get quite a bit of noise going over significant bumps but I'm used to that so it didn't bother me.
I am very satisfied with their performance so far. I felt very confident in their performance with the extended periods at high speeds. I have no regrets and would certainly buy them again based on what I have seen to-date. Time will tell on other topics like tire wear.
