What's wrong?
The tires on 2018-2025 Mack Granite (Gr) and Granite (Gu) trucks carry the truck's weight, keep the tread in contact with the road, and absorb heat and load during service. For heavy trucks, DOT testing under FMVSS 119 confirms that a tire is certified for use in the United States and suited to the vehicle class it is sold on.
On these Mack trucks, certain BGSTL317 tires were installed even though they had not been DOT tested and confirmed for the vehicles. Mack traced the issue to its sales tool, which allowed non-DOT certified tires to be ordered for trucks intended for the United States. The defect is not a broken tire part in the usual sense. It is a certification and fitment problem: the tire on the truck lacks the required DOT compliance confirmation.
An owner will not feel this compliance issue through the steering wheel or brake pedal. There is no warning sign before failure. The dealer remedy uses an FMVSS 119 DOT compliant tire in place of the affected tire.
