15 MPG combined is the price you pay for unadulterated capability in the 2025 Chevrolet Silverado Mud Terrain Tires 4WD, powered by the 6.2L V8. No one choosing this Silverado prioritizes efficiency. They need its off-road ability, its strong towing capacity, and the visceral experience of a big, naturally aspirated engine. Fuel economy is simply a secondary concern, a practical reality accepted in exchange for this kind of performance.

City and highway performance

The EPA estimates the 2025 Chevrolet Silverado Mud Terrain Tires 4WD 6.2L V8 manages 14 MPG in the city and 17 MPG on the highway. The city figure reflects the engine working harder in stop-and-go traffic, battling its own substantial weight plus the added rolling resistance of the mud-terrain tires. The highway number, while better, still reveals the fundamental truth of a large-displacement engine pushing a full-size truck through the air. While the 10-speed automatic transmission tries to optimize efficiency, the engine’s appetite is undeniable. Owners living in rural areas may see slightly better real-world highway numbers thanks to fewer stops and higher average speeds.

Annual fuel cost

The EPA calculates that the annual fuel cost for this specific Silverado configuration is $3,850. This figure is based on driving 15,000 miles per year, with a mix of city and highway driving, using the national average fuel prices. It’s an important number to consider, as it highlights the ongoing expense of owning a truck built for serious work and play. If your driving habits lean more towards city driving or you frequently tow, you can expect this annual cost to be even higher. While fuel prices fluctuate, $3,850 provides a clear benchmark for budgeting.

Real-world expectations

Do not expect to consistently achieve the EPA numbers in the real world. This Silverado’s natural habitat often includes challenging terrain, heavy loads, and aggressive driving. Mud-terrain tires, while fantastic off-road, significantly impact on-road fuel consumption due to their aggressive tread pattern and increased rolling resistance. The 6.2L V8 is also incredibly responsive to throttle input, and its sound encourages drivers to its power. If you frequently indulge in heavy acceleration or off-road excursions, your MPG will plummet below the EPA estimates. The aggressive aesthetics, its burly stance, encourage drivers to *use* the power on tap.

How it compares

The Ford F-150 Raptor, while offering superior off-road performance in some scenarios, achieves a slightly worse 15 MPG combined with its high-output 3.5L EcoBoost V6. A Ram 1500 TRX, with its supercharged 6.2L V8, is rated at a dismal 12 MPG combined. The buyer interested in less gas might consider the standard 5.3L Silverado, which can approach 17 or 18 MPG combined in 4WD configuration but lacks the raw power and capability of the 6.2L. Even the smaller Chevrolet Colorado ZR2 struggles to match the non-ZR2 Silverado’s efficiency, highlighting the compromise inherent in maximizing off-road capabilities.

Tips to maximize efficiency

Regularly check and maintain your tire pressure. Mud-terrain tires are especially sensitive to pressure changes, and proper inflation significantly reduces rolling resistance, improving fuel economy. Consult the sticker on your driver’s side doorjamb for the recommended PSI when running these tires on the road.

Anticipate traffic and avoid aggressive acceleration. The 6.2L V8 is responsive, but every hard acceleration burns fuel unnecessarily. Smooth and gradual acceleration will significantly improve your city MPG, though it may require some restraint.

Reduce unnecessary weight. Carrying around extra cargo in the bed will negatively impact fuel economy, especially with the already heavy mud-terrain tires. Remove any unnecessary tools, equipment, or materials when not needed.

Consider using a less aggressive tire during seasons when off-roading isn’t a priority. Swapping the mud-terrain tires for all-terrain or even standard highway tires can noticeably improve fuel economy and reduce road noise during daily driving.

Plan routes strategically to avoid stop-and-go traffic. Idling consumes fuel, and extended periods of idling in traffic can significantly reduce your overall MPG. Using navigation apps to identify and avoid congested areas can lead to meaningful fuel savings.
