If your wheels regularly send road gravel and chippings flying into cars at high speed, you've "got pressure".
After a fresh pump, I managed to chip the windows of a fried chicken shop *and *hit a bus window really hard with flying gravel, but the bus did not chip.

Felt guilty, but did not stop. Bad me.
