- yencabulator 6y agoIf you have rugged off-road tires and you sort of know what you're doing (know how low you can go, can measure PSI, etc): yes. If you have factory highway tires in your average passenger car, beware, you're pretty likely to tear a sidewall.

- yencabulator 6y agoAll tires are fine to lower the pressure on, to a point where the sidewalls don't yet start bending and twisting. Factory (= cheap) highway tires have weak sidewalls, so if you drop PSI too low they'll tear the sidewall pretty easily, or slip off the wheel. Off-road tires have stronger sidewalls. Many American car owners have never even put on a spare tire. Telling that crowd to start lowering their tire pressure is a recipe for damaged tires.
- joshocar 6y agoI would not recommend someone who can't change a tire drive on sand. Most of the time you are going to be driving a truck if you want to go on sand, which will have truck highway tires and can handle lower pressures just fine. We regularly run down at 17-18psi with standard truck highway tires when on sand.
