Tires Continental or Nokia

Others have recommended it the Conti Extreme Contact Sport (and Sport 2) are great tires for dry but one of the best wet tires as well. It out performs the Michelin in the Wet by a noticable amount with the current compounds

If you’re gonna be “cheap” and just run all seasons, I got no complaints with the Continental Extremecontact DWS 6

Blizzaks are great. Nokian Hakkapeliitta's are out of this effing world.

Not sure what you went with but the Nokian WR G4 are great tires. I've used 4 pairs of the WR type of tires over 15 years in Michigan, Oregon, Utah(In the Canyon), Washington and Colorado on a front wheel and AWD drive SUVs/cars. They work great and are snow tires.

I'm currently running continental premium contact 5's on my C30. They do certainly grip well! My only minor gripe with them is that the sidewall seems a little stiff for the suspension

The OEM Dunlops and Falkens are absolutely rubbish and needs to be replaced to get a true sense of ride and handling of the mazda6. I replaced by Dunlops at around 18k miles with Conti DWS 06 and it completely transformed my car.

I’ve driven an AWD crossover with Continental True Contacts in deep heavy snow without issue.

Go for the Nokian Hakkapeliitta. Best tires by far! They're not cheap but definitely worth it. I have the studded ones on both of my vehicles and they're bullet proof

when you lose traction, it feels like it will never get to a stop (and that's with Nokian Hakkapeliittas).

I've had a bad experience with Continentals. Difficult to balance, not a great ride, hard in cold temperatures.
