It does when going off road...

I've never heard of this, but I don't think that's true.

An under-inflated tire will “flex” more when cornering and stopping. Under-inflated tires don't respond as quickly as they would if they were properly inflated, so you lose some of the performance and safety benefits built into the tire by the manufacturer.

What you're mentioning:
Quote:
Off-roading
When traveling over rough terrain, mud, or deep sand, many off-roaders will “air down” (decrease tire pressure) to keep more of the tire’s footprint gripping the ground. They also decrease their speeds, since their tires will now be less responsive when it comes to steering and stopping.

I could maybe see the an under inflated tire grips loose ground better than hard ground, but I don't think and under inflated tire is a good idea on asphalt or winter conditions.
