The Sidewall design ensures maximum flexing without fatigue, the profile has excellent vertical stability for load retention and return side support. The design allows for high compression to ensure smooth inner deflection around small radii. Another important design feature is that the Sidewalls can be pressed from both sides when mounting, this offers much higher bond strengths and security.The fabric insertion is of the diagonal type which gives excellent tear resistance and also allows the Sidewall to flex more easily.The rubber compounds used have been tested to ensure maximum flexibility along with high abrasion resistant and high tensile strength.Sidewalls has proved the design and rubber compounds work together in harmony increasing the life of the Sidewall and ensuring maximum durability.Type SStandard Construction in heights from 40mm to 120mmType SRStandard construction but with Diagonal Fabric Reinforcement.Type HDSRHeavy duty construction including fabric reinforcement as standard in heights from 120mm to 300mm.The fabric reinforcement is of the diagonal type ensuring maximum flexibility with high vertical stability.
