Default GM certified issue - dry rot tires

I picked up 2016 LT1 with 15k miles certified used in December. I just noticed the tires are dry rotted real bad. I’ve put 6k miles on the car and I find it highly unlikely this just happened and was likely missed during the inspection process.

Anyone else have any experience like this and do you think I have a leg to stand on trying to get the tires covered


under warranty?

Wow, did that in just 4 years? Seems a little premature, does that have anything to do with being summer only tires? You would think if that was present at the time of the certification, it would have been caught.

I bought the car with aftermarket wheels and tires so they aren’t even the originals.

From my understanding a CPO cannot have any aftermarket items. I am basing this on my CPO sheet - any non OEM parts on car Yes or No. It looks like you live in PA - super soft tires in the cold might have done this. Just guessing. I hope somehow you can get some new tires for free or discount but I doubt it

When were the tires made ?, there is a code on the sidewall.

Doesn't look like they would be covered. This is from the GM CPO website:


What's Included

Almost every part of our vehicles is covered under the 12-Month/12,000-Mile2 Bumper-to-Bumper Limited Warranty (excludes normal wear and maintenance items). See below for the list of exclusions.

What's Not Included

  • Tire damage or wear
  • Damage due to bedliners
  • Damage due to accident, misuse or alteration
  • Collision, fire, theft, freezing, vandalism, riot, explosion or objects striking the vehicle
  • Misuse of the vehicle such as driving over curbs, overloading, racing or other competition. (Proper vehicle use is discussed in the owner manual.)
  • Alteration or modification to the vehicle, including the body, chassis or components, after final assembly by Chevy, Buick or GMC.
  • Coverages do not apply if the odometer has been disconnected, its reading has been altered, or mileage cannot be determined.
  • Damage or corrosion due to environment, chemical treatments, and/or aftermarket products
  • Damage due to insufficient or improper maintenance
  • Damage due to contaminated or poor-quality fuel

I believe it's a 4 digit code with the first two being the week of the year they were made and the last two being the last two numbers of the year.

Here's the 172 Point Checklist. Tires are checked for remaining tread.

Be careful with aftermarket wheel and tire packages. I purchased a set for my C5 and the tires were already 3 years old when I mounted them "new" on my car. That's part of the reason many of those package deals are deals, because the vendor is pushing old(er) tire stock. I learned this the hard way after learning how to read the tire manufacture date on the sidewalls.

In fairness, this doesn't apply to all vendors. I ordered a set of Forgelines with OEM spec Michelin Pilot Sports (non-Cups) from Gerry at CW4L for my 2019 C7 Z06 w/Z07 package and those tires were less than a year old.

Those aren't even Michelin tires, much less the stock PSS versions - so I would doubt CPO would warranty them.

Not oem. No warranty. Maybe able to get Michelin to warranty them.

Not sure that is dry rot. I have had dry rotted tires and they looked a lot worse than that. The sidewalls had cracks not just the tread.

To me it looks like someone drove these tires in below 20 degrees weather and they cracked from the cold. Maybe not dry rot

One thing for sure....I would tread (no pun intended) lightly with them till you get them replaced...Not only can you loose control if they come apart but they will do serious damage to the fenders when they do...Good Luck

Good luck in discussions with the dealer, but based on the CPO checklist and exclusions, I doubt they will be covered.
