I too drive in Canadian "summers" and for that reason recommend you consider fitting the latest ultra high performance all season tires instead (did I really say that?). I'm not kidding. On the street these are actually higher performance than the dedicated summer tire most of the time.

Reason becomes clear if you've ever got your summer tires into their proper temperature window just driving on the road. The first time you do is a revelation. Trouble is you need about 30 minutes of pretty hard driving, cornering hard, getting on the gas and braking hard, to get those tires "up to temperature". A couple of laps on track will do it easily but not so much on the road.

The relatively softer compound used in the all season versions heats up to its optimum much more readily. Bottom line is you are able to drive the all season tire at its best temperature more of the time on the road then you can do with a summer tire. I'm not knocking the summer tire. If I lived in CA it'd be a no brainer. Up here, not so much.

Bonus, the all season tire still grips very well down to freezing whereas the summer tire gives up when ambient drops below about 10 C. I'm a happy convert.

PS you still need winter tires for snow and ice.


What?! So you're saying a set of Michelin pilot super sports wouldn't perform as soon as an all season set like maybe our stock primacies? Can someone else confirm this? I have a friend running super sports in our Canadian weather and they are pretty damn grippy.. well then again that's compared to my nearly bald primacies.

I do have a set of winter tires.
