I run Nokian Hakkapilitta studded winter snow tires 285 35 R19 on Z06 knock off wheels I ordered from c7z06owners.com . Pretty reasonable cost. As I recall, all four wheels were $1,100 U.S. and they are literally identical to my stock chrome wheels with the exception of the center cap. For that you need to order some Corvette decals on ebay. I got 19" all around, since Nokian doesn't make a 20" snow tire in the dimensions you need. Besides, with a 285/35 the sidewall is higher, and they fit perfectly. Also, you can get the snow tires at Kal Tire. They deal in Nokian Hakkipilittas. I swear by them, and will never buy any other brand of snow tire. I have them mounted on my Z06 knock offs, as well as on my WRX STi, and my son runs them on his '02 Bug Eye WRX. Don't settle for less than those tires. You won't be dissapointed. Then, when spring comes, I simply use my race ramps to lift the car up. Jack it a touch and install jack stand, and swap my summer Pirelli PZeros on. I've shelved the Michelin Cup 2s.....after about 5000km they were toast. I could use one in a pinch as a spare, or for the track, but other than that, they are worthless...... If you don't have "race ramps" (that's the actual name of the brand) get some. They make working on the car for stuff like this effortless. I can swap all four wheels out in about a half hour.........................no charge.................done.
