Deeper grooves improve traction for off road use but are noisy when on road use.
so they can have more traction
When it rains, cars sometimes hydroplane because the water underneath the tires supports the weight of the car and causes it to loose traction. Grooves give another channel for water to escape. As for off-road cars, the tire grooves are not much deeper rather they are larger and have more room to go up and down. In my Jeep Wrangler, the tire grooves are the same depth as an Acura TL and a Honda minivan. Maybe on other off-road cars they help the car travel through gravel, rock, sand, and snow to gain more traction.
The differences are the size and the purpose. Regular tires are made to grip the asphalt, and also fitted with grooves to push water away, keeping it from hydroplaning. The off road tires are thicker, and the grooves are much deeper, giving it the ability to have good traction in the dirt and rocks.
Tyres have treads to give better grip on the road, especially on a wet road.

Tires or the road.
Off-road tyres have deeper treads to help get a better grip on mud and gravel.
Yes, the tread is much deeper as well as the rubber is much softer.
Tires need the grooves to be able to get a grip when weather is not the best. They provide a place for water, ice and snow to go and allow the rubber tread to make contact with the road. Racing cars often use tires with no grooves at all, but the weather has to be dry and the pavement clean. On a passenger car, even a little water can cause hydroplaning, where the tire is on water rather than the pavement.
so you have grip on the road.
