Depends on what you're thinking about. On a hard, even surface a tire w/o treads can generate more friction than a tire with treads, as it will have a bigger engaged surface area.
OTOH a tire with little/no treads will be prone to hydroplaning, which is very low friction.
Then if you're talking about a soft surface a smooth tire will be able to generate less friction than a treaded tire. On a soft surface the treads can bite in which offers more engagement than a smooth tire that might just slide on the top.
If you were to look at the rolling resistance of the wheel as a whole, then a smooth out tire will roll lighter than a treaded tire.
A big part of rolling resistance is the energy lost in deforming the tire as it rolls along. With treads you get something called tread squirm, where the different blocks and ridges of the tire tilts and wiggle around under the pressure, with each tilt and wiggle meaning that there is energy lost to the deformation of the rubber. And energy lost means increased rolling resistance.

How is friction increased in tires?
by lowering the pressure in the tires but it depends on what kind of soil the track is in, for example for wet conditions you need more traction as you need to lower the pressure in the tires so you get more drive. Buy a pressure Gauge.
How do you stop a toy car from going down a ramp?
Either decrease the slope of the ramp, increase the friction on the axels of the car, or make the tires stick to the ramp in some fashion.
Why increase friction?
You would increase friction so that you wouldn't slip, by using the brakes on your car of bike you increase friction to stop yourself. Hikers increase friction between their feet and the ground by wearing hiking shoes that grip the ground better. Tires on cars that create more friction make the car go faster, because instead of sliding, the tires grip the ground and push off.
Does friction increase or decrease when tires are worn out?

As there's less rubber in a worn tire it will deform more easily, offering lower rolling resistance.Depends on road conditions.On a firm, dry surface a smooth tire will have more friction than a treaded tire. That's why race cars tend to have smooth tires AKA slicks.The reason why treaded tires are generally required for road use is that slick tires do very poorly in rain. When you drive through a puddle, water gets squished between the contact patch and the road, and w/o the tread pattern allowing water to escape, the tire is lifted off the road and hydroplaning occurs.Slick tires also do very poorly on softer Surfaces where treads would have dug in and found grip.
What are five examples of friction being increased?
~Putting chains on truck tires in the snow ~Rubbing your hands together ~Car Brakes ~Race Cars have special tires to increase traction and friction ~When you walk it's friction that keeps you from sliding all over the place
Do wheels have treads?
No, tires have treads.
Why tires have grooves on their surface?
To increase friction

Does the spoiler of a car increase or decrease friction between the tires and the road?
The spoiler on a car is meant to create down force on the back or front of a car depending on where it's placed... Which means that yes it does increase friction but it also helps with traction at higher speeds
Do truck tires have tread on them?
Yes, all vehicle tires have treads on them. Truck tires will usually have larger and deeper treads than regular sedans.
How do you stop a toy car from going down a ramp?
Either decrease the slope of the ramp, increase the friction on the axels of the car, or make the tires stick to the ramp in some fashion.
What would be an example of a helpful decrease in friction?
Deep tread added to snow tires.
What are found on tires of vehicles to increase friction?
Cuts, curves and gaps.
Why do we need rough on tires?
we need rough tyres to increase friction

How does tire tread increase friction between tire and road?
tires are made of rubber and rubber can cause friction
What can you do to increase friction between the tires and a race track?
The track and tires are both sprayed with a special solvent compound.
