I live in SC, which has similar weather, and our roads are JUNK. I've run those on three diff Mazdas an a CR-V. With 5,000 mile rotations, you won't have any issues getting 60,000 out of them.
Bingo. You'll appreciate them, for real.
And as far as being $240 more, look at it this way: these tires will last at least 60,000 actual miles. Assuming 12,000 miles per year, that's 5 years, or $4 per month. Pretty much nothing.
Know this: none of these cleaners will do *anything* for the valves. Those you have to clean manually. Luckily it's a hell of a lot easier that you probably think. I had never done it before, and it was 2 hours from pulling the car into my garage to pulling back out. I could do it in WAY under...
I have a Kuda in my Mazda. They look so good, pretty much like the factory would have made.
I hot glued a big magnet to the back and it works great.
