About 25 years ago I picked up a '66 Coronet 440 4 speed car for $1500 because the guy got a flat on the freeway, removed his 15" wheel, and installed a 14" spare that was about 2" less in diameter. He only made it about 35miles before he tore up the rear end. I run different sizes on my '65 GTO and carry a spare that fits the stock size front wheels. If I get a flat in the rear, I'll have to rotate the other front tire to the rear and the good rear to the front (it will barely fit) and drive lopsided. Better lopsided than burn up my limited slip. So far, no flats!! In fact, in over 40 years of driving GTO's, I've NEVER had a flat in one. I get flats in my Toyota 4x4's ALL the time, though!!
