All season tires and Celica just doesn't ring into my head. I have driven on the stock all season tires and they sucked. I have driven on high performance "summer" tires and they sucked ten times in the snow.
I have said this before and I will say it again for the degenerates. If you drive in regions of the US that produce snow some months of the year and you drive a $20,000 + car or a Celica get snow tires. Period. amongst the periods...
Get a cheap 15" or even 16" stock Celica wheels and equip them with snow tires. The narrower the better. Nokian HR, WR or something are the best you can get and I made the research on it. Most of us have aftermarket wheels, so keep them for dedicated summer/wet and dry tires and the cheap throw backs for the winter tires.
In fact, my friend that owns a Dodge F-150 just put on his winter tires and doesn't haven't the luxury of an extra set of wheels. I'm going to slap on my 15" stock wheels with my winter tires already on there in a couple of weeks also. Good luck all
