Common Signs that Your Semi Truck Needs a Wheel Alignment

by Billy Bob’s Repair & Tire • 29 September 2025
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.

What are some of the most common reasons that semi trucks overheat?

by Billy Bob’s Repair & Tire • 2 September 2025
When a semi truck overheats, it can bring a delivery schedule to a grinding halt and create costly downtime. Overheating is more than just an inconvenience—it can cause significant engine damage if not addressed quickly. Because semi trucks are designed to handle long hauls and heavy loads, their cooling systems must work properly under demanding conditions. At the first sign of overheating, it’s important to be proactive about addressing it. At Billy Bob’s Repair & Tire, we provide mobile semi truck cooling system repair in the greater San Antonio,TX area. Here’s a look at four common causes of semi truck overheating. Low Coolant Levels Coolant is critical for regulating engine temperature, and semi trucks require large amounts to handle the heat generated by long drives. If coolant levels drop due to leaks in hoses, the radiator, or the water pump, the system won’t have enough fluid to dissipate heat effectively. Even minor leaks can soon cause overheating in heavy-duty engines, making regular coolant checks essential. Faulty Thermostat If the thermostat gets stuck closed, coolant cannot circulate, and the engine will overheat rapidly. A faulty thermostat can also create inconsistent temperature regulation, which puts added stress on the cooling system. Replacing a malfunctioning thermostat promptly helps ensure reliable cooling on the road. Radiator Problems Semi truck radiators handle immense heat, and when they become clogged with debris, corroded, or damaged, their efficiency drops. Because radiators in semi trucks work under such heavy demands, keeping them clean and in good condition is critical for preventing breakdowns. Water Pump Failure The water pump is responsible for circulating coolant throughout the engine and radiator. If the pump fails, coolant flow slows or stops, leading to overheating. Warning signs include coolant leaks and unusual noises. Since water pump failure can quickly escalate into major engine damage, it’s important to address it ASAP. 24/7 Mobile Semi Truck Repair in San Antonio For expert roadside mobile semi truck repair in San Antonio and the surrounding area, contact Billy Bob’s Repair & Tire at  (210) 796-3891  .

Common Big Rig Trailer Problems that Should Be Addressed ASAP

by Billy Bob’s Repair & Tire • 3 August 2025
For truckers and fleet operators, keeping a big rig trailer in top condition is essential for both safety and efficiency. Ignoring trailer issues can lead to breakdowns, delivery delays, or even serious accidents. To avoid costly downtime and ensure your rig remains roadworthy, it's important to recognize and resolve trailer problems as soon as they arise. At Billy Bob’s Repair & Tire, we provide expert trailer repair in the greater San Antonio, TX area. Here are five common big rig trailer problems that should be addressed without delay. Faulty Lights Lighting issues are among the most common and most hazardous trailer problems. Brake lights, turn signals, and running lights must all function properly to ensure safety on the road. Malfunctioning or flickering lights can make your rig invisible at night or prevent you from signaling lane changes or stops, increasing the risk of accidents. These problems can often be traced to damaged wiring, loose connections, or failed bulbs. Tire Wear or Damage Trailer tires endure a lot of stress, especially during long hauls and heavy loads. Uneven tread wear, bulges, or low pressure can all compromise tire performance and lead to dangerous blowouts. Regular tire inspections and prompt replacements are crucial to maintaining safe traction and avoiding roadside emergencies. Suspension System Issues The trailer’s suspension system helps distribute weight and absorb shocks from the road. Signs of suspension problems include excessive bouncing, noisy operation, or a visibly sagging trailer. A qualified technician should inspect and repair any suspension issues to prevent further damage and maintain smooth, safe performance. Brake System Malfunctions Trailer brakes play a vital role in stopping power and overall safety. Common issues include air leaks and damaged brake drums. Any signs of reduced braking performance should be checked by a mechanic immediately to ensure safe operation. Structural Damage or Cracks Over time, trailers can develop cracks in the frame, floor, or walls due to stress and corrosion. Structural damage compromises the integrity of the trailer and can put cargo at risk. Even small cracks can grow and lead to major failures under heavy loads. Early detection and repair are key to extending the life of the trailer and keeping it safe on the road.
