Tips & Warnings
Rest one tube on the top of the trunk and the other on the side of the trunk for a sedan-model vehicle.
Rest both tubes on the back glass of the trunk's door for a lift-back window (minivan) or SUV. Open the two arms of the bike rack and position them away from your vehicle.
Pull each strap after traveling over especially rocky or rough terrain to eliminate any slack that may have built over the course of your trip.
