Phoenix experiences extremely hot summers. The temperature of your truck, including the tire temperature, can impact on how effectively it runs. Learn more about your tires' reactions to heat and how to prevent serious damage below. When you need roadside tire services in Phoenix, call Emergency Roadside Truck and Trailer Repair.

Overinflation

Overinflation is a common issue for semi truck tires in hot weather. As temperatures rise, the air inside the tires expands, causing the tire pressure to increase. Tire pressure rises by one pound per square inch (PSI) for every ten degrees Fahrenheit increase in temperature. When the temperature gets too hot, the tires on most cars have a PSI of 30-35, which puts you at risk of a tire blowout. If your tires feel hot to the touch, it’s a good sign they're likely to blow out. To determine whether your tires are overinflated, you can also use a tire pressure gauge.

Avoid a Blowout

Don't release the air from your tires if you believe they are over-inflated. You run the risk of releasing too much air, which could harm your tires. Wait until your tires have cooled before you drive. To keep your tires from rubbing against the road, always drive at the speed limit. Your tires will degrade more quickly because increased friction generates more heat. Your tires are more likely to blow out if they are thin or balding. Get new tires for your truck just to be safe.

Semi Truck Overheating: Common Causes that Should Be Addressed ASAP

by Emergency Roadside Truck and Trailer Repair • 8 August 2026

A semi truck's engine works under tremendous stress, often hauling immense loads over long distances and through varying terrain. Because of these demanding conditions, the cooling system must function properly to keep the engine operating within a safe temperature range. When an engine overheats, it can lead to expensive repairs, extended downtime, missed deliveries, and even catastrophic engine failure. Fortunately, many overheating issues can be prevented with routine maintenance and prompt repairs. At Emergency Roadside Truck and Trailer Repair, we provide mobile semi truck cooling system repair in the greater Phoenix area. Here are four common reasons that semi truck engines overheat. Low Coolant Levels One of the most common causes of engine overheating is a low coolant level. Coolant absorbs heat from the engine and carries it to the radiator, where it is released before the coolant circulates back through the engine. If coolant levels drop, the cooling system cannot effectively regulate engine temperature. Drivers should regularly inspect coolant levels and address any leaks immediately to prevent overheating. Failing Water Pump The water pump is responsible for circulating coolant throughout the engine and radiator. If the pump begins to fail, coolant flow becomes restricted, causing engine temperatures to rise. Warning signs of a failing water pump may include coolant leaks, unusual noises, steam from the engine compartment, or a rising temperature gauge. Replacing a worn water pump promptly helps prevent severe engine damage. Clogged or Damaged Radiator The radiator removes heat from the coolant before it returns to the engine. Over time, dirt, bugs, road debris, and other contaminants can block airflow through the radiator fins, while corrosion can alter coolant flow inside the radiator. A damaged or clogged radiator cannot dissipate heat efficiently, making the engine much more likely to overheat during long hauls or steep climbs. Routine cleaning and inspections help keep the radiator operating effectively. Faulty Thermostat The thermostat regulates coolant flow based on engine temperature. If it becomes stuck in the closed position, coolant cannot circulate through the radiator, causing temperatures to rise rapidly.
