A question about wheel size...

Right now the wheels I have on my car are the 16" stock 5 spoke chrome wheels. The tires on there are really good dry/wet tires, but they suck ass in the snow. My Cavalier is being scrapped and I have a set of snow tires on that on steel rims, but they are 15". My question is, would it be ok for me to put those on my Grand Prix, or do I have to get 16" steels and rubber?

The Cavalier bolt pattern is 5 X 100mm. Your Grand Prix is 5 X 115mm. The wheels from the Cavy will not fit on the Grand Prix hubs.

DOH! lol... thanks for the response... guess ill just sell the tires to a friend... they only have about 600km on them
