More friction, you need friction in order to get out. Place something in front or behind the tire in order to get out, even a cloth towel will help.
It is better to have less friction because it will be easier to get out.

It is better to have less friction when a car tire gets stuck in mud or snow because less friction allows the tire to spin more easily and gain traction to get out of the obstacle. Increasing friction in these situations can worsen the situation by making the tire more likely to dig into the mud or snow.
Sledding on snow, ice skating, and sliding on a playground slide are activities that work better with less friction.
A baseball curveball is better with less friction. Less friction allows the spin on the ball to be more effective in creating movement, causing the ball to break or curve more sharply as it approaches the batter.

Friction is force that opposes an objects motion. Therefore, the less friction the object encounters, the less opposition it will have to its direction of travel. The less opposition it has, the faster it may go. Theoretically, a moving object that encounters no friction will continue to travel at a constant rate for EVER.
Ice skating: Less friction allows for smoother gliding on the ice. Aerodynamics: Reduced friction helps vehicles like airplanes move more efficiently through the air. Roller coasters: Less friction between the wheels and the track allows for faster, more thrilling rides. Bearings: Reduced friction in bearings enables smoother movement in machinery and devices.
Trains are better for the environment - as they produce less pollution per passenger than cars do.
so that less friction is caused, and to improve speed
less wind resistance, better fuel mileage
Less weight = better fuel mileage.
