How many gallons is a Toyota Tundra gas tank?
The standard fuel tank on most current Toyota Tundra models is 26.4 gallons. In this article, we explain what that means for everyday driving, how the size is applied across different configurations, and how to verify the exact capacity for your vehicle.
Current generation tank size
Official Toyota specifications for the current-generation Tundra (model years 2022 through present) consistently list a 26.4-gallon fuel tank across most trims and cab/bed configurations sold in the United States. There is no widely advertised larger factory option for this generation.
Key details about the current tank size:
- The standard capacity is 26.4 gallons (approximately 100 liters) for most 2022–present Tundra models.
- Capacity generally applies across common cab and bed configurations in the U.S. market.
- Some aftermarket modifications or regional variations may affect perceived capacity, but they are not factory specifications.
In short, for the majority of current Tundra buyers, the fuel tank sits at 26.4 gallons, with no widely available factory option to increase that single-tank capacity for this generation.
Why tank size matters
Fuel capacity influences how far you can travel between fill-ups, especially when towing or traveling in areas with limited refueling options. While the 26.4-gallon tank provides a solid range for most everyday driving, actual range depends on engine choice, drivetrain, payload, terrain, and driving style.
Summary
Bottom line: the Toyota Tundra’s gas tank is 26.4 gallons for the current generation. Always verify the exact capacity for your specific trim and year using the owner’s manual or the factory window sticker, especially if you’re looking at special editions or regional variants.
