To receive roadside assistance you must call the toll-free number located on the Adventure Assurance card received at the time of purchase. A service provider will be dispatched to your location. In the event of a flat tire, the service provider will replace the tire with your inflated spare. Service will also include off-road towing for BFGoodrich tire customers whose vehicles are stranded in difficult terrain such as mud, snow, sand, or ice. With a couple of decades of experience supplying premier off-road tires to extreme enthusiasts, we know we have to look out for the service providers too, so service will depend solely upon safe tow truck access to the scene as determined by the service provider. The service professional will ask to see the card provided with purchase. If you need a replacement card, please contact the place of your tire purchase. This service is not transferable and is only for the vehicles for which the tires were purchased. Service is provided on a sign-and-drive basis. There is no out-of-pocket cost for the covered service, up to the maximum benefit allowed. You simply sign the receipt and drive away. If the cost of service exceeds the amount allowed, you will be responsible to pay the difference at the time service is rendered. Services are limited to a maximum of $60.00 per incident and three incidents per year per customer.
