The general recommendation is to wait until after the break-in period specified in your owner's manual, which is typically the first 1,000 miles, before doing any significant towing. This allows the engine, transmission, brakes, and other components to seat properly, ensuring long-term reliability.
Towing places a substantial load on a new vehicle's drivetrain. During the break-in period, internal engine parts like piston rings are bedding in with the cylinder walls. Aggressive use, such as towing, can generate excessive heat and prevent proper seating, potentially leading to increased oil consumption and reduced engine life. Similarly, the transmission and differential gears need time to mesh smoothly.
Consult your owner's manual for the manufacturer's specific guidance. Some trucks or SUVs built for heavy work may have shorter or even no specified break-in period, while others might be more restrictive. The manual will also provide the correct procedure for breaking in your specific vehicle, which usually involves varying speeds and avoiding constant RPMs.
Even after the break-in period, start slowly. For your first tow, choose a light load and a short, flat route. This allows you to get a feel for the vehicle's performance and check that everything—like trailer brakes and lights—is functioning correctly before undertaking a long, heavy haul.
| Manufacturer | Recommended Break-in Period | Towing Advice During Break-in |
|---|
| Ford | 1,000 miles | Avoid towing for first 1,000 miles. |
| Chevrolet/GMC | 500 miles | Avoid towing for first 500 miles. |
| Ram | Varies by model; see manual | Generally recommends no heavy towing for first 300 miles. |
| Toyota | First 600 miles | Avoid continuous high speeds and sudden acceleration. |
| Jeep (Wrangler) | 300 miles | Vary driving speed and avoid wide-open throttle. |
