The 2021 Toyota Tundra’s towing capacity is dependent on trim level. The Tundra SR and SR5, the lowest tiers on the trim ladder, are still top of the game when it comes to towing, with a maximum towing capacity of 10,200 pounds.
While it might seem counterintuitive, the more expensive trim levels have lower towing capacities. The two most expensive with the 4WD Crewmax specs have a towing capacity of 8,800 pounds.
If your friend opted to save money buying his Tundra, he got the truck with the best towing capacity in the fleet. But if you need to tow 9,000 pounds or less, you can’t go wrong regardless of trim level.
