I’ve been running some 205/50R16s on my 2007 Corolla in Buffalo, NY, and they’re pretty solid. The ride’s smooth and handling is great—perfect for nitty-gritty winter conditions. A buddy of mine opted for 215/45R17s for a sportier look and edge, but I’d recommend weighing the weather and your usual driving scene first. Everyone’s different—what works for someone might not work for another. Plus, check that they fit without affecting clearance issues!
Remember, chat with some local mechanics in the USA/Canada if you’re still unsure. They might have useful insight based on your area’s climate and terrain nuances. Go with what feels right for you!
