Worth knowing about the 2026 Enclave
- Spare. This vehicle carries a compact (temporary) spare.
- Tire chains. The manual says not to fit tire chains on this vehicle; wheel-well clearance is too tight.
- Tires. The manual says not to use tire chains or textile traction devices on any size.
- Torque. Tighten lug nuts to 140 ft-lbs in a star pattern with a torque wrench, and re-check after the first 50 miles. This figure is from the owner's manual; an impact gun will overshoot it.
- Roof load. The 220 lb roof limit is the dynamic figure for driving and includes the rack itself. It is not a limit for a rooftop tent when parked; the manual gives no static figure.
- Roof. The 220 lb limit includes the cross rails, or the accessory maker's lower rating if it is less.
- Fuel. All-wheel-drive models have a 21.7-gallon tank.
