Subject: General Grabber Tire Failure at 13,464 Miles I am reporting a catastrophic General Grabber tire failure on my 2026 GMC Sierra at 13,464 miles\. I am concerned that the failure may involve a defect in materials or workmanship and am requesting that it be recorded and reviewed as a potential safety defect\. The tire is a General Grabber HTS60, size 275/60R20\. Photos of the failed tire are available\. I can provide the tire’s DOT identification number if needed\. After the failure, we contacted a GMC dealership in [XXX], and attended an appointment at Bergstrom in [XXX]\. We received conflicting information from the dealerships and GMC customer service about warranty coverage\. Because I needed a usable vehicle and could not wait for the warranty dispute to be resolved, I purchased a replacement tire from Walmart and my husband installed it\. My safety concern is that this tire suffered a catastrophic failure at only 13,464 miles\. The cause has not been confirmed, and I would like the federal safety agency to assess this report alongside any similar complaints\. Please advise what additional information or documentation would assist your review\.

The contact owns a 2024 GMC Sierra 1500 equipped with Maxxis Tires, Tire Line: Bravo HT-750, Tire Size: 255/80/R17, DOT Number: 120NK10015028. The contact stated that after the front driver 's-side tire became flat, the contact discovered that the spare tire originally equipped on the vehicle failed to fit the front wheels but did fit the rear wheels. The vehicle was towed to the dealer, who determined that the spare tire failed to fit the front driver's side wheel due to a factory-installed brake modification, causing the spare to not fit over the front brakes. The dealer replaced the front driver's side tire. The manufacturer was made aware of the failure. The tire failure mileage was unknown. The vehicle failure mileage was 14,000.

On March 14 2026 i was driving from [XXX] . To [XXX] to have my tires checked because i felt a strong vibration on my steering column and truck itself, it was getting worse so i took it to my mechanic who does my regular maintenance on truck. After inspecting Tire Goodyear Wrangler SR-A ( 275 55 R20) front passenger , mechanic informed me that the tire had separated from radial. And i need to get another tire right away, since there was non in stock we did the next best thing we took the front passenger tire the affected tire put it in the back and put the rear good tire up front. The next day i was on my way to purchase the replacement tire when the tire blew out. I was on a heavily traffic road [XXX] . I managed to take control of truck doing about 40 mph at the time and drove it off the road to a safer spot to look at damage. Well the passenger rear tire witch was originally on the front that had the separated radial blew a chunk out of the inner sidewall. I put on the spare and went and replaced the tire with another goodyear new tire. On march 28 as i was coming home from [XXX] Ca late at night the driver side rear tire blew as well again had to put on spare and next day took to local mechanics in [XXX] , and checked tire and again i was told that the tire separated from radial and that was the cause of blew out, they inspected all the tires at this point since this was the second tire from the same DOT set with less then 12000 miles that had separated. Well they found a third tire that had aldo separated and had a flat spot on driver side front tire, now there are 3 tires from the same set, coincidence, i dont think so i replaced the second and third tire. One the third day April 1, 2026 the passenger side front tire blew as well, now i have 4 tires that had radial separation with 2 that had blew out chunks from inner wall, with less then 12000 miles and less then a year old, in a mater of a month.

I purchased a 2024 GMC SIERRA 1500 Denali Crew Cab Diesel 3.0L After several times bringing the truck to the dealership I purchased from and conduct all service related work. They finally found a crack/whole in the sidewall that was not done by any road hazard to cause damage but looks like a manufacturer defect. This is now not only prominent on one tire but two of the tires. The area is on the covex area of the tire. BRIDGESTONE ALENZA A/S 02 Size 275/50/R22 This is a huge safety concern as a blowout at 65MPH could cause significant harm to not only people in my vehicle but to others. This is an advisement to get the right attention on this before something catastrophic or deadly. With plenty of tread on the tires (6/32), which equated to 50% life on the tire. The dealership is trying to make me pay for a manufacturer defect of $600+ for the two tires.

Tires are LT275/65R20. While driving on interstate at approximately the speed limit and low 80 degree temperatures in South Carolina with proper placard pressure tire inflation checked two days prior, the truck developed a faint vibration which got worse over three or four miles. I slowed my speed and pulled over at next offramp and visually inspected truck for signs of vibration. Including looking over tires. It seemed like a drive line issue, however truck is a 2021 model with only 38,000 miles. After I could not find anything out of place I got back on the interstate to see if problems still existed. I was only traveling at 45 mph and vibration was getting worse, so I tried to slow and make it to next offramp when the driver side tire blew out causing me to have to quickly react to prevent having an accident. The tire tread and multiple parts of the truck inner fender guards and liner were thrown out into traffic and truck bed side is badly damaged. Prior to blow out there were no warnings on the dash board to to indicate any sort of issue and I verified tire pressures when I stopped after the vibration initially set in. The TPMS system was working properly at the time of the blowout. I have the tire if further inspection is warranted. My safety was at risk when tire blew out on the interstate along with vehicles traveling around me to avoid hitting the flying debris and tire tread. Further this was driver side tire and I had to change the tire on the side of the interstate with traffic right beside my vehicle. I called GMC and they said they would do nothing to help because they see tires as a maintenance item and truck is out of warranty period. I am a mechanical engineer having worked many years for major tire company as a tire design engineer. I am very familiar with load ratings, tire wear, life expectancies, and I believe theis tires failed prematurely. I bought this truck new and have always had tires properly inflated a never overloaded.

Vehicle experienced a catastrophic mechanical failure characterized by a percussive "shotgun blast" noise from the rear chassis, followed by an immediate, total loss of braking power (pedal to the floor) and a violent loss of directional stability. This incident represents an aggravated safety failure of known GMT900 platform defects. The technical chain of causality began with the factory exhaust manifold fasteners suffering a metallurgical shear, a universal defect documented under GM Bulletins 19-NA-218, PIP5075, and PIP4701. This shear created a high-velocity, high-heat exhaust leak directed at the brake master cylinder and vacuum assembly. This "heat soak" event compromised the engine-mounted mechanical Brake Vacuum Pump (Recall N192268490 / the federal safety agency 19V645) and destroyed the internal seals of the Master Cylinder (Special Coverage 15143 / the federal safety agency 11V599), resulting in total depletion of vacuum assist and hydraulic pressure. Simultaneously, the "shotgun blast" and violent swerve were caused by structural failure consistent with Rear Brake Caliper Bolt Fracture (GM 13247 / the federal safety agency 13V342) and Rear Axle Shaft/Pin Fracture (GM 14892 / the federal safety agency 14V819). This mechanical collapse caused the caliper to strike the wheel, resulting in a catastrophic rim blowout and immediate loss of tire pressure. Despite the vehicle having aftermarket long-tube headers installed, the root cause of the heat-related brake failure was the failure of the OEM GM manifold fasteners which snapped off in the cylinder head, as documented in the aforementioned bulletins. Under the Magnuson-Moss Warranty Act, the manufacturer remains liable for these pre-existing safety-critical defects. The vehicle is at Glenn Polk Chevrolet for a 901-series Product Allegation Investigation (Case #90199492). This report is filed to demand federal oversight into these life-threatening defects. The combo of failed fasteners, rim blowout, and compromised braking created a vehicle that was both unable to be steered or stopped

On [XXX], at approximately [XXX], while driving northbound on [XXX] between [XXX] and [XXX] (Austin, TX) at roughly 65 mph, I suddenly heard a loud cracking and popping sound from the front of the vehicle. As I began to ease off the gas, unsure of what was happening, I observed what appeared to be a black object quickly shoot upward from the front driver’s side of the vehicle while traveling at highway speed. I immediately took the next exit [XXX] ) to assess the situation. I had no idea what to expect; my mind kept jumping to either hitting road debris or maybe even a blowout. To my astonishment, once I was safely on the side of the road and out of my vehicle, I noticed that the front left fender flare had completely detached from the vehicle suddenly and without warning while cruising at normal highway speeds. The 2023 GMC Sierra 1500 in question had approximately 29,800 miles at the time of this incident. I immediately contacted the dealer to schedule a repair, and all pertinent records, including photographs and a repair invoice, can be made available upon request.

I purchased a set of Firestone Destination A/T2 tires from Firestone in Southaven, MS. I had the tires for less than 16 months. I took the tires in for inspection & was told the treat belts had separated from the tires. The tires are a hazard. the tires are 275/55R20. Driving on the interstate, I had to pull over as it felt as though the truck would overturn/rollover. They must be recalled. I contacted Firestone, they were of little to no assistance. Unable to obtain a refund or credit. I googled info on firestone tires & a plethora of information exhibited the same thing, problems with tread separation.
