Every car would present some challenges with a significant slick size change. I can't think of any car that would present no challenges.
It's the cheapest and easiest way to quickly change the effective gear ratio, but if you don't have the rest of the car set up to handle the change, you can get yourself in trouble quickly too!!
We would drop from a 14 X32 X15 on a dragster we ran, to a 13 X29 X15 for certain shorter tracks. The slicks were mounted on wheels that interchanged and we're make adjustments with timing and a two step chip in the ignition.
