Increasing downward force on a pneumatic car tire without increasing tire pressure causes the tire's contact patch to deform, and you lose grip. This can happen in driving due to weight transfer.

You would need something other than pneumatic tires, or some sort of dynamic tire pressure system.

Either one seems more practical than rockets on a car. And modifying pneumatic tires to minimize this problem might be possible, if it's something that just hasn't been prioritized because it wasn't that big of a problem before. Also, a sophisticated fan system might be able to make the downforce larger, yet less variable than natural downforce.

You actually increase grip but lose traction overall.
