I have an '07 G6 GT w/sport package. It includes traction and stability control and 225/50 VR 18 Goodyear Eagle LS2 tires. Although the tires are labeled M&S, I'm suspicious of their "all season" capability in snow. Unfortunately, there are only 3 tires available for this car the Goodyear, Bridgestone Potenza (also M&S), and Bridgestone Blizzak Winter Tire.
I'm looking for a reasonably priced alternative to the tires. Would it be possible to drop down to 225/55 17 tires which are half the price. I don't know what that would do to the handling (traction/stability control).
Any ideas?
