Temperature plays a significant role in how your trailer tires perform. The main reason for that is that as temperature increases, the pressure inside the tire also rises, which can lead to overinflation if not carefully monitored. This happens because the heat excites the particles, which then causes the air to expand.
As you drive on the road, due to heat produced from the friction between the tire and the road, the pressure inside the tire increases. If the temperature is too high, the tire could become overinflated, leading to lower traction, uneven wear, and a higher probability of damage from potholes or curbs. Also, if the pressure is sufficiently high, it can cause a catastrophic blowout, i.e., the tire could burst.
Conversely, in colder temperatures, the air inside the tire contracts, potentially leading to underinflation. Underinflated tires can overheat, wear prematurely, and reduce fuel efficiency. Also, they tend to increase the chances of fishtailing happening, which is a significant safety issue.
Therefore, it's vital to regularly check tire pressure and adjust it according to the manufacturer's recommendations, considering temperature variations.
