What is the minimum that the coefficient of static friction of the car without skidding?

A car going at v = 29.7 m/s (67 mph) rounds a curve of radius R = 50.0 m, where the road is banked at an angle of θ = 30.0◦. What is the minimum that the coefficient of static friction between the tires and the asphalt must be so that the car can go through the curve without skidding?
