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.
What else can I help you with?
Would wider tires increase or decrease friction?
Wider tires increase friction due to larger contact area with the road. This can provide better traction and handling, especially in wet or slippery conditions. However, wider tires can also increase rolling resistance, which may affect fuel efficiency.
Does friction increase or decrease when the vehicles are on the road?
Friction between the tires and the road increases when vehicles are on the road. The friction helps the tires grip the road surface, allowing the vehicles to accelerate, decelerate, and corner effectively.
Give some examples to show that friction is increased deliberately?
One example is using sandpaper to increase friction between objects. Another example is applying anti-slip mats or tapes to surfaces to prevent sliding. Additionally, car tires are designed with treads to increase friction with the road for better traction.
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.
Does friction increase or decrease when tires are worn out?

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.

Do wheels have treads?

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.

What would be an example of a helpful decrease in friction?
Deep tread added to snow tires.
How do you increase friction on a bike?
You can increase friction on a bike by using tires with a higher tread pattern, inflating the tires to the recommended pressure, and keeping them free from debris. Additionally, using brake pads with more grip and adjusting them correctly can also help increase friction when braking.
Why do we need rough on tires?
we need rough tyres to increase friction
