For your situation, I'd actually suggest looking at the Nokian Hakkapeliitta R5. I've tried many over the years, and honestly, they're legendary for deep snow. Since the Mazda 3 sits low, you really need that aggressive tread pattern.

Another solid technical choice is the Michelin X-Ice Snow. It's a bit more stable on cleared roads but still handles icy hills with caution. Definitely talk to a pro installer about sizing though... I'm always a bit paranoid about clearance! Hope this helps!

+1 to what was said earlier. Those Nokians are great, but honestly, the price tag is usually a total nightmare. Since you're driving a Mazda 3, I'd suggest Continental VikingContact 7 instead. I've had issues with road noise on other brands, but these are way quieter and much better value. Unfortunately, premium brands have gotten so expensive lately, so these are a solid, cost-conscious alternative for those icy hills. Hope this helps!

Quick question - what's your wheel size? Honestly, low-profile tires struggle with clearance. I've had issues with 18s, so I'd suggest Yokohama iceGUARD iG53 205/60R16 for better sidewall bite and safety.

In my experience, you should definitely prioritize safety since that Mazda 3 sits so low. Honestly, I've tried many over the years and I'd recommend Bridgestone Blizzak WS90. They're amazing for those icy hills! I'm always a bit cautious, so I'd also suggest chatting with a professional installer just to be 100% sure about the clearance.

TL;DR: Go with Bridgestone Blizzak WS90 for the best grip on ice. Seriously, don't risk it with cheaper sets!
