The RY023 has a five-rib tread design. The semi-rounded shoulder treatment reduces shoulder tearing and step wear, and provides lateral stability and water dispersion. The RY023 offers improved performance and traction for any RV. Sidewall abrasion guard reduces damage to sidewall caused by curbing. Heavy-duty construction will exceed the demands of any RV applications. Note that the tires come with a max recommended speed of 75 MPH or 110 KMH.
