Sorry to hear about the curb!! The F1-G2 tires are expensive also. Just saying...
There are several threads on winter/cold weather tires for the SVTPP. Bottom line, stock G2's are not recommended to be driven on below 40 deg f. It's in the manual. Goodyear put out a warning about tire cracks with pictures. They have no traction below 40 deg. The owner's manual says to do what I did- get a spare set of wheels and all seasons for winter use. The G2's actually work well when warm.
I run Nitto Invo's on the front 275/35/19 and 315/35/20 on the back.
Do you have any clearance problems with the nitto's? I like the svtpp wheels. Don't really want to switch back and forth. Only drive my car when it is really nice outside. No rain, salt, sand, or snow.
