What should be checked regularly to prevent tire blowouts in an RV?

Regularly checking tire pressure and tread condition is crucial in preventing tire blowouts in an RV. Tire pressure affects the tire's ability to support the weight of the vehicle and maintain proper contact with the road. If the pressure is too low, it can lead to overheating and ultimately a blowout. Conversely, over-inflation can also cause increased wear and tear on the tires and lead to blowouts.

Tread condition is equally important as it provides traction and helps to channel water away from the contact surface. Insufficient tread depth can increase the risk of hydroplaning in wet conditions and reduces the tire's overall grip on the road, increasing the likelihood of failure.

While other options may involve aspects of vehicle maintenance that are important for overall safety and performance, they do not directly relate to preventing tire blowouts. Wheel alignment and suspension concerns impact handling and tire wear but aren't the primary factors leading to blowouts. Similarly, checking fluid levels, like brake fluid and engine oil, is vital for the vehicle's performance, yet these elements are not directly involved with tire integrity. Therefore, emphasis on tire pressure and tread condition is essential for maintaining tire safety and preventing blowouts.
