Additional Features
This tire does not feature a dedicated rim protection, which typically provides a reinforced area to shield your wheel rims from curb damage and scratches. Furthermore, it is not a run-flat tire.
The Wintercraft WS71 is constructed with reinforced rubber, contributing to its higher load capacity. Reinforced tires (often marked ‘XL’ or ‘Extra Load’) are designed to carry heavier loads than conventional tires. Always consult your vehicle’s owner’s manual or registration document to confirm if your SUV requires tires with reinforced construction.
