| Tire Sidewall problems |
I am reporting a potential safety defect involving goodyear wrangler trailrunner at tires size lt275/65r20. I purchased a new 2025 GMC Sierra 3500hd in August 2025. By the time the vehicle reached approximately 1,800 miles, noticeable sidewall bulges appeared on both rear tires. As a 36-year automotive professional, I recognized the serious safety risk posed by this condition and replaced all four tires at my own expense with a different brand. Since then, I have seen multiple reports of similar sidewall failures on brand-new trucks, which suggests this may be a systemic issue. Based on my experience and these reports, I believe this defect may be known to both goodyear and gm but has not been adequately addressed. I urge the national highway traffic safety administration (NHTSA) to investigate this matter to determine whether these tires pose a significant safety risk to the public. Vehicle information: make & model: 2025 GMC Sierra 3500hd tire model: goodyear wrangler trailrunner at tire size lt275/65r20. Mileage at issue: ~1,800 miles purchase date: August 2025 summary of issue: sidewall bulging on new tires, potential for blowout or loss of vehicle control.
