At what tire temperature does it become dangerous?

Dry tires typically operate within a normal temperature range of 90 to 110 degrees Celsius. Caution is advised when temperatures exceed 100 degrees. Tire blowout: Hot weather can cause tire deformation and reduced tensile strength. Additionally, improper tire pressure, aging tires, or diminished performance can lead to sudden tire blowouts. Note: Before driving, it's advisable to check the tire pressure appropriately. Due to temperature effects, the gas inside the tire expands automatically, increasing the tire pressure from 2.3 kg to over 3 kg. To maintain proper tire pressure, it is recommended to fill tires with nitrogen in summer, reducing the filling pressure by 10%.
I've been driving for almost 20 years, and excessive tire temperature is a common hidden danger. It becomes particularly hazardous when the temperature exceeds 120 degrees Celsius. High heat softens the rubber and causes a sharp increase in tire pressure, leading to deformation or even blowouts. During prolonged highway driving, friction-generated heat can easily push tire temperatures above 130°C—I once narrowly avoided an accident because of this, thankfully pulling over in time to discover cracks on the tread. Prevention is straightforward: maintain proper tire pressure (check when cold), avoid sudden acceleration or speeding, especially in summer when the road feels like an oven. I also recommend stopping every 1-2 hours for a 10-minute break to let the tires cool and inspect for wear. Safety always comes first—this small habit has saved me from trouble multiple times.
From my understanding of automotive structures, tire design has temperature limits. The danger point is around 121 degrees Celsius, where rubber decomposition accelerates, internal pressure becomes imbalanced, and the probability of a blowout increases. In real-life situations, high-speed driving or overloading can cause tire temperatures to rise rapidly. I always use a tire pressure monitor for early warnings, and once it alerts, I slow down and stop to check. Related preventive measures include choosing appropriate tires (summer tires are more heat-resistant) and avoiding excessive tire pressure (which exacerbates heat buildup). Regular tire rotation and wear inspection are also crucial, as they can extend lifespan and reduce risks. Remember, safe driving isn't about luck—it's about meticulous maintenance.
