Sidewall tear!

Ugh! That tire does not look good at all. Please get it replaced ASAP. You do not want to drive too far on that; in fact, I'd change over to the spare, but that's me. You stated you have a GT but a 16-inch rim? I thought all GT's had 18s (size 215/50R18), but maybe Canada is different? If you have 16's, then you might have better luck with tire selections, especially if you are going to replace all four. A quick check of Tire Rack shows they now offer, in size 215/50R18, a Pirelli Cinturato P7 all season as well as the stock Yoko Avid S34. The Pirelli's are less expensive, plus well-rated with a longer expected tread-life. Again, that's the 18-inch rim, which is what my GT has. Glad that someone now offers an alternative A/S tire to the stock Yokohama's. Anyway, if you do have 16-inch rims (size 215/60R16), then you have many choices. Personally I like Continental, as I have considerable experience with this tire brand. I had Conti's on my Acura and they performed better than the stock Michelin's. Plus you can usually get them at a very competitive price. Good luck.
