Why Do Trailer Tires Blow Out in the Summer? (And How to Prevent It) <\/b><\/span><\/h2>\n

If you have ever asked yourself, why do trailer tires blow out in the summer, the answer lies in a deadly combination of intense asphalt heat, underinflation, overloading, and exceeding the tire\u2019s maximum speed rating (often just 65 mph). Additionally, many new trailers come equipped with low-quality factory tires (colloquially known in the RV community as “China bombs”) that cannot handle the severe sidewall flexing caused by high temperatures. To prevent blowouts, upgrade to reputable ST tires, replace them every 4 to 5 years regardless of mileage, inflate them to the proper cold PSI, and use a Tire Pressure Monitoring System<\/span> (<\/span>TPMS<\/span><\/a>). <\/span><\/p>\n

The Terror of Summer Road Trips: The RV Blowout Epidemic<\/b> <\/span><\/span><\/h2>\n

It is the peak of July. You have the family loaded up, the camper hitched, and you are cruising down the interstate on the way to the campground. Suddenly, you hear a deafening bang, followed by violent shaking. By the time you pull over, your trailer\u2019s wheel well is shredded, the fender skirt is gone, and you are left staring at a mangled mess of wire and rubber wrapped around your axle.<\/span><\/p>\n

If you browse any <\/span>RV community<\/span><\/a>, such as <\/span><\/span>r\/GoRVing<\/span><\/i>, during the months of July and August, you will see endless threads titled “Blown tires, so frustrating” or “What’s up with all the trailer blowouts!”<\/span><\/span><\/p>\n

Trailer tire blowouts are not just an inconvenience; they are a massive safety hazard that can cause thousands of dollars in body damage to your rig. But exactly why <\/b>do trailer tires blow out in the summer so frequently? It ultimately comes down to a few critical factors: heat, speed, weight, and factory tire quality<\/p>\n

1. The Factory Budget Tire Phenomenon<\/b><\/span><\/h2>\n

One of the most heavily discussed topics among veteran RVers is the quality of factory-installed tires. In an effort to keep costs low, particularly on “ultra-light” travel trailers, manufacturers often equip brand-new rigs with the cheapest possible <\/span>ST (Special Trailer)<\/span><\/a> tires manufactured overseas.<\/span><\/p>\n

These budget tires have earned the unfortunate nickname “China bombs” because of their tendency to explode without warning, even with very low mileage.<\/span><\/p>\n
