Rubber is decent, but recommended for drivers with decent experience due to the sharpness of reaction and instability in the rut (rut grooves on asphalt) With its pros: Low price, good tenacity both on asphalt (dry and wet) and on the ground. Soft. Low noise level. Cons below: Very sharp reaction to the actions of the wheel. Valkaya (it may be necessary to try to increase the pressure). Bad friends with the rut.
