In the Costco thread, I mentioned that I was disappointed in their snow/slush performance, which is pretty much the reason why I buy winter tires. I want excellent snow/slush performance. These are definitely not the be-all and end-all.
So, I bought Blizzaks for the CX-3 instead. We'll see how that goes.
FWIW, my MIL has the Xi3s on a CX-3. I was blown away by how good the car, as equipped, performed in very wintery weather while they were snowbirding and I was making sure the battery didn't die (before we smartened up and just bought a trickle charger).
Thing is, I'm not sure how much of that was the tire vs the AWD system that Mazda has equipped its cars with of late (a very capable system, despite what some youtube tests show).
I'm sure with the WS80s you'll do great - I hope so, since that's what I've equipped my Mazda with
The Fozzie is still running WS70s from 2011, but have 9/32" left so I can't justify replacement. If traction sucks this winter, I'll swap 'em early in the season without blinking.
As for any thoughts on cheaping out/knock-off, no-name tires, I just don't get it. You're putting winter tires on to get more traction in colder/snowier/icier conditions. You're doing it for safety. You're doing it to be better off than the OEM/3-season/summer tires your car is already equipped with.
...so why would you ever consider a tire that may not perform any better? Why would you not want a top-tier tire? There are so many instrumented tests that show the cheapest winter tires perform the same or worse than 3-season tires. A little research goes a LONG way.
I just don't get it. I'll never get it.
