Narrower tires with harder rubber
It is better to have less friction because it will be easier to get out.
less
Compared to previous versions of tires, radial tires have less rolling friction or less friction with the road while in motion. The result of this is that the tires are generally quieter when driving on the road than the previous version and also allow for better fuel economy.
smaller cross-section of tread in contact with road
More
New tires actually have less friction on dry surface than old, bald tires, but once the old tires hit water, you new tires quickly win.
The more friction, the quicker the vehicle will stop, meaning less stopping distance.
they create more friction that's how they stop
When a vehicle hydroplanes, the friction the tires are against is something other than the roadway - typically, it's a layer of water between the tires and the roadway. As the water has much less resistance and friction than asphalt, the tires spin much more freely.
Flabby tyres produce more friction with the road.Less air pressure creates more surface friction, the less surface friction there is the better. (Example look at the very skinny narrow tyres on road racers as they don't need a lot of surface friction while mountain bikes have thick tyres as they need more friction)
so that less friction is caused, and to improve speed
Yes if you want better road holding. No if you want less friction and better fuel economy.
