For long-haul truckers and fleet operators, keeping semi trucks in good working condition is essential for safety and profit. When a truck breaks down, it can lead to missed deliveries and long stretches of downtime. While regular maintenance can prevent many issues, certain mechanical and electrical problems are especially common in heavy-duty trucks that log thousands of miles each month. At Billy Bob’s Repair & Tire, we provide 24/7 roadside semi truck repair in the greater San Antonio, TX area. Here are four common reasons that semi trucks break down. Engine Trouble Engine failure is one of the leading causes of roadside breakdowns for semi trucks. Over time, engines endure tremendous stress from hauling heavy loads and operating for long hours in demanding conditions. Common causes of engine trouble include overheating, oil leaks, worn belts, and injector problems. When a semi’s engine begins to lose power, make knocking noises, or emit excessive smoke, it’s a clear sign that immediate attention is needed. Electrical System Failures Semi trucks rely heavily on complex electrical systems to power everything from the lights to electronic control modules. When electrical issues arise, they can cause major disruptions. Dead batteries, loose wiring, corroded connections, and failing alternators are common culprits behind electrical failures. Drivers should have their electrical systems checked regularly, especially before long trips, to reduce the risk of roadside breakdowns. Brake Problems A truck’s braking system is crucial for safety, and any failure can be catastrophic. Because semi trucks use air brakes, even small leaks can lead to decreased braking efficiency or even failure. Regular inspections of air lines, brake shoes, and compressors can prevent these dangerous problems and help ensure dependable stopping power under all conditions. Tire and Wheel Issues Tires are among the most frequently replaced components on a semi truck, and for good reason. Blowouts, uneven wear, and tread separation are all common problems that can lead to breakdowns or accidents. Overloaded trailers, improper inflation, and alignment problems accelerate tire wear. Regular inspections and proper tire maintenance help prevent these issues. 24/7 Mobile Semi Truck Repair in San Antonio, TX For expert roadside mobile semi truck repair in San Antonio and the surrounding area, contact Billy Bob’s Repair & Tire at  (210) 796-3891  .

Keeping your semi truck in top condition is essential for safe and efficient operation. One often-overlooked aspect of truck maintenance is wheel alignment. Proper alignment helps ensure your truck handles smoothly and reduces wear and tear on tires. When alignment issues are ignored, they can lead to more expensive problems. At Billy Bob’s Repair & Tire, we provide expert wheel alignment for semi trucks and other heavy duty vehicles in the greater San Antonio, TX area. Here are four common signs that your semi truck may need a wheel alignment. Pulling to One Side If your semi truck drifts or pulls to one side when you’re driving on a straight, flat road, it’s a classic indicator of alignment problems. This pulling effect not only makes it harder to keep the truck steady but can also increase driver fatigue. Over long hauls, constantly correcting the steering can become both exhausting and dangerous. Uneven Tire Wear One of the most noticeable signs of alignment trouble is uneven tire wear. If you inspect your tires and see more wear on one edge than the other, or if the tread seems inconsistent across the surface, it often means your wheels are out of alignment. Left unchecked, this uneven wear can shorten tire life and compromise traction, making driving less safe. Crooked Steering Wheel A misaligned semi truck often reveals itself through the steering wheel. If your wheel looks crooked or off-center when driving straight, it’s a sign that the wheels themselves aren’t aligned properly. Shaking or Vibrations Another warning sign is a shaking or vibrating sensation in the steering wheel or throughout the truck. While vibrations can sometimes come from unbalanced tires or other issues, poor wheel alignment is a frequent culprit. Vibrations can worsen at higher speeds, making it uncomfortable and even risky during highway driving.
