Check the following webiste and scroll down the large coefficient of friction table. http://www.roymech.co.uk/Useful_Tables/Tribology/co_of_frict.htm The table contains COF valus for rubber on cement in both wet and dry conditions. Also, understand that rubber is a considerably soft material, the COF is easily effected by the amount of normal force, the temperature, etc. Hope this helps.
According to the the Physics Hypertextbook(URL http://physics.info/friction/) the coefficient of kinetic friction of a car tire on dry grass is 0.35.
The coefficient of static friction for rubber on tile is 0.39 according to the book "Mathematical Methods For Accident Reconstruction" by Harold Franck and Darren Franck, 2010, pg 65.

You need two different materials to determine the coefficient of friction. Without another material you cannot know what the coefficient of friction is.
Over 9000!
Rubber has more friction than an ice cube. Ice has almost no friction what so ever.
Depends on the other surface. Coefficients of friction are generally tabulated for pairs of materials. Emery cloth on Teflon, for example, will have a lower coefficient of friction than emery cloth on rubber.
It doesn't work that way - friction is not something that is "produced". The way it works is that you have a coefficient of friction for two surfaces that are in contact. Then you use that coefficient of friction, and multiply it by the normal force, to calculate the actual FORCE of friction.For the coefficient of friction, you need to specify a PAIR of substances; for example, carpet against glass would probably have less friction than carpet against rubber.

A higher coefficient of friction indicates that two surfaces in contact have a greater resistence. A lower coefficient of friction indicates that the two surfaces in contact have less resistence. Soccer cleats on grass have a greater coefficient of friction than skates on ice.

Rubber will have a high coefficient of friction on most surfaces, but we cannot know whether there is more or less friction unless we have something to compare it to.

the equation for static friction coefficient is:static friction coefficient = force required to break bond / weight of object (tire)you need the friction coefficient between rubber and grass, say its 0.5, this means the force you have to apply to equal the friction force is:0.5 = x / 30x = 0.5 * 30x = 15 lbs fanything greater than 15 lbs f will break the bond and accelerate the tire.notes :1 / moving friction coefficient is usually less than static friction coefficient, so youve less drag once its moving.2 / friction coefficients are never greater than 1.0actually , some friction coefficients do exceed 1.0 , see google / friction coefficients table

A high coefficient of friction between the rubber bottom of the shoe and most types of terrain.
No. Coefficient of friction is not measured in units.
quality of the Surface is affected to the Coefficient of friction
