Reinforced Tyres
Reinforced tyres feature additional structural layers in the sidewall and casing to support greater loads at higher pressures. Marked with 'RF' or 'Reinforced' on the sidewall, they are functionally equivalent to XL tyres. Fitting reinforced tyres is essential when the vehicle manufacturer specifies them, as standard tyres would be unsafe under the required loads.
