They'd have an outer radius about 1" larger (about 8%) than the stock size. I think they'd fit ok but the speedometer/odometer will be off and the overall gearing will be a little higher. The usual recommendation is to stay within about 3 - 4% of the stock radius.
They should work fine, do yourself a favor, if you haven't had the car in the snow before, put about 100lbs of something in the back... It really helps keep the rear planted.. I used corn in 50lb bags over last winter... In the spring it went to my dads chickens....lol....
I think there may be clearance problems. The already anemic Vibe will have even less power due the higher final drive ratio of the larger tires. 7.4% larger tires put more load on the brakes. At 100km/hr the speedo will read 92.5km/hr which in Quebec will undoubtedly lead to an eventual speeding ticket. Narrow is better for winter. 195/65/15 is what most people use and even they handle kind of squishy compared to the stock 205/55/16. There's cut off point between saving money and taking unnecessary risks.

LOL Oh, I know man, I wasn't questioning that, I was just concerned if you had, had the Vibe in the snow yet... I'm from Buffalo NY(was) and live in VT just below you.. So I know my winter driving well myself, and I can tall ye, some weight in the back of the Vibe in the white stuff helps quite a bit...
Anti-lock brakes work based on differential rotation speeds. As long as the tires are all the same size there shouldn't be an issue with that.On both of our '06 Vibes, the speedometer reads about 3% higher than actual with the stock tires. So substituting the specified size would result in it reading about 4 - 5% low instead. Just keep it in mind when you're driving and you shouldn't get undue speeding tickets. (But I'd suggest timing a few miles on a road with mileage markers at a steady speed to check the calibration - or use a GPS, but timing is usually more accurate.)I agree with those who suggested that narrower winter tires would be better. But if the choice is between the OEM 'all-season' and good winter-specific tires that are a little wider then I'd opt for the winter tires.
