14" Rims on a '91, 740 Turbo?
 

I am getting ready for winter here in Maine and last year was the last year my studded snow tires were any good. I have an opportunity to pick up some nice new studded snow tires that are already on rims and were originally bought for my friend's 240.

1) My 740 has 15" rims on it right now, can I put 14" rims on it?

2) Besides a slight odometer/speedo discrepency, will there be any badside effects to switching to 14" rims with studded snow tires for the winter?

Thanks,
