The problems with General Motors‘ late-model full-size trucks continue to mount. Both the Chevy Silverado 1500 and GMC Sierra 1500 are being recalled again despite an earlier recall of 33,000 vehicles for the same issue. The problem continues to stem from the Continental-brand tires that were “overcured” during the manufacturing process. Here’s what you need to know about this new round of GM recalls. 

The Chevy Silverado and GMC Sierra models plagued by tire problems

The trucks in the new recall were already part of an effort a few months ago, GM Authority reported. They involve 2019 GMC Sierra 1500 and Chevy Silverado 1500 pickup trucks. Their tires, specifically the Continental brand, were overcured. There have been no reported problems with tires made by other brands. 

Compounding the problem is the earlier recall for these troublesome tires. Due to an internal error in General Motors’ service bulletin, car dealerships failed to detect and replace the faulty tires in specific models properly. 

So, what exactly is an overcured tire?

“Much like a tasty salami or Italian prosciutto, tires need to be cured. But instead of salt and spices, this process involves heat and pressure,” Roadshow explains. “A critical part of the manufacturing process, this step is what gives tires their final shape. But they can also be overcured …”

The tire issue has led to sharp criticism of America’s biggest automaker. It seems odd that General Motors would only now issue the recall on 2019 models. Though a tire’s lifespan is less dependent on time and more so on mileage and usage, there’s no doubt some owners with faulty Continental tires have already replaced them due to normal wear-and-tear. However, Continental, not GM, might be the one to blame for the delay. 

The risks of driving on overcured tires

An overcured tire is a serious safety concern that shouldn’t be ignored. The faulty tire can cause a break in the sidewall, creating a sudden air loss or belt edge detachment, causing tread loss and belt loss. 

Both conditions can cause a vehicle to lose control, increasing the risk of a collision. Drivers may experience excessive vibration in the tires while driving. Sudden air loss might also occur while operating the vehicle, creating another serious safety concern, according to the National Highway Traffic Safety Administration. 

If your 2019 Chevy Silverado 1500 or 2019 GMC Sierra 1500 has Continental tires, you should inspect the tires for signs of damage before driving. Experiencing any of these malfunctioning hazards while driving can happen immediately, creating a frightening and dangerous situation.  

The solution for 2019 Chevy Silverado and GMC Sierra owners

The good news is that GM is experienced in managing recalls. The automaker offers an online recall center for consumers with faulty parts and vehicles.
