Suddenly my 20k tires start falling apart in chunks. I have never seen this before, it's like they're disintegrating for no good reason. Cooper STT here I come...

Sharp rocks or the alignment has gone whacky.  Could it be the former since those tires are coated with a fine dusting of white dirt?

We see plenty of trucks/suv with that tire, the Continental LX20.  They use it on Tahoe/Yukon, Traverse, Blazer and Silverado/Sierra. 

 

None of them have ever looked like that. 

 

Something is up with either alignment or driving conditions/roads you are on.

No caustics, no rocky areas, alignment is at factory settings. White dust is from neighbor’s construction that settles on my driveway. Damage is similar at all four tires which has me stumped.

 

I have several trucks with all different kinds of tires throughout the years and have never seen this happen, especially since this one doesn’t see the offroad or jobsite duty my other ones go through.

I’d stop driving on them immediately.

 

I can’t think of anything that would do that short of soaking the tire in some acid.

 

i’d contact the tire manufacturer and demand a different set of tires, maybe even some upgraded ones. Make sure to act like a suburban housewive and rip them a new one and tell them you are very scared.

I see you wrote a review on their website


Here’s a separate review with a similar issue. I’d try to find more personally and then contact them

 

The front tires on my 2016 Silverado have pieces of rubber ripping off the front tires only. The rear tires are fine and seem intact. I had my tires rebalance and checked at Discount Tires due to what felt like a vibration felt in the steering wheel when driving at highway speed. have rotated my tires as required by a local Chevrolet dealerships as required. I primarily drive the vehicle to work and drive on the highway occasionally.

Yeah I figured I’d finally ask around to see if this was a common thing because I couldn’t find similar cases for this particular set while searching or any correlation through my driving experience. Truck tracks straight and smooth just like when I bought it.

 

Basically I just wanted to see if this is about the time/range these tires tend to fall apart. The only other tire that I can remember having problems with were Federal Couragia but those were a different kind of mess.

 

Thanks for all the input gents.

My father and I both have those tires on our trucks. Both truck are at 40k mile range. His tires look like but not that bad. His alignment is perfect according to the alignment shop. I'll try and snap some pictures after work.

Here are my continental LX20’s @ 22k miles. I rotate every 7500. I see nothing like yours. A few small spot of rubber missing. I would contact continental and give them plant code and date of manufacture. It’s located by DOT marking. Also send some photos. They could of had a bad batch/run. It’s good to get it on record. I never had a tire do that.

Looks like chemical damage as an underlying cause of breakdown and degraded by abrasion. Just a guess.......Use automated or commercial DIY car wash bays? If so maybe concrete dust embedded in the sipes of the tire are reacting with the hydrofluoric acid used in industrial care wash soaps and degrading polymer additives in that particular brand model of tire.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      tl; dr I've now reached the 6th floor of hell. I'm chronicling my journey for my morning readers.   Pulling the top of the intake apart was moderately easy but it involved a lot of parts, connections, and minutae. I was preparing for the new fuel lines to arrive ("nut and bolt kit" it's called). The fuel line connections are notched and held in place by the manifold and a metal plate with a T27 screw.   It's on the back of the intake, under the firewall, with little clearance, and two hard metal fuel lines in the way. I was using Franken-tools (weird combinations of 1/4 inch ratchet with/without an extension, with a bit holder for my T27) to get in there. One of my sockets and bits fell off and has yet to emerge on the floor. I lost a second setup and that's when I almost started throwing tools. But that was the point at which I had gotten traction on the Torx head, and it promptly stripped. No more traction.   I started humming "1-877-kars-4-kids" because I was about at that point. You know what? I'm $1500 into this thing and I can make it disappear just as quickly. This isn't fun anymore. I had spent a lot of time already "tidying" around the engine bay: Fixing all the "someone's been here before!" BS. The truck has been exclusively dealer- and shop- serviced and I'm reminded of why I never let other people work on my cars unless absolutely necessary.   Speaking of dealer service. This truck has a 1" stack of records going back to 1995. I put them all in an excel spreadsheet, date/mileage/description.   The CPI spider has been replaced 4 times in 85k miles. The EGR? Another 4. Multiple, multiple O2 sensors. One Cat. 4? Sets of plugs and wires, and I swear half the stack is diagnosis paperwork for "misfire, runs rough, extended crank, dies at stoplights".   GM was producing some proper crap back then. And it was still well within the era of brittle/crappy plastic. (Windows 95 was released the same month this truck was sold new, we HAD the technology!!)   There (was) a plastic shroud around the evaporator core and HVAC fan in the engine bay. I noticed a chunk of it missing so I poked at it some more and it literally shattered. Touched it some more and pieces were crumbling off. Had a good laugh. Clearly whatever plastic garbage they were using had broken down over 30 years and was literally turning to dust. That was a good half hour of using a shop vac to remove the rest of it.   Back to it.   I was going to give up for the evening but then decided I'm already level 10 pissed off at the stripped screw: G* D* it, give me my tools back -- and my JOY. We'll do this the hard way: The whole intake is coming off.   Blazer won Round II. After finally finding and accessing the 12 intake bolts and using a pry bar to unseat it from the heads, it popped loose in an explosion of gunk and grime raining down into open ports. Awesome.   6 times I reminded myself: Be careful of the temperature sender on the front of the intake.   YEAH, I forgot again and snapped it clean off in the removal. Add another $20 to the ever-growing list of new parts this thing is consuming.   The shame is, long before removing the intake, I had changed the oil in prep for Tuesday's momentous fuel line replacement that was going to be the magic fix and I'd have a running Blazer to tool around in this next weekend. The intake removal, including raining gunk, also gushed dirty coolant all over the valley. Of course it did. Welp, there goes another $35.   I now need an intake gasket set, bolt set, coolant temp sensor, another 5 quarts of oil, some RTV. Don't worry, I've already got 3 new jugs of Dexcool and a thermostat waiting. I'll fill it with clean water first to get it running, dump it, and then add the Dex later on in case... well, let's not go there. I'm only tearing this down once, next time the truck is going on Marketplace for FREE.   Oh, and I'm going to need vacuum hose for all the stupid connections placed at the rear of the engine which have since disintegrated. Come on, GM....tell me you don't do that anymore?   Oh, and the ears on the distributor where the cap screws down are both cracked. I mean, why not put a new distributor in it too. You get a distributor, YOU get a distributor, Everyone gets a new distributor!   This truck isn't out of the woods yet...I'm already questioning how much more time I'm willing to sink in.

      Bent valve in 2025 GMC Canyon Denali - Requires engine swap at 14K miles

      By William Aldrich · Posted

      NewDude, thank you for the suggestions!    I did follow up and the dealer indicates he has an open CX case and is working with DPAC (Dealer Parts Assistance Center).   Per the dealer, GM has had a quality spill and is not providing an update for when a replacement engine will be available.

      Poll: Does your truck have the rear window leak?

      By Silver Yeti · Posted

      That's interesting.   There was a factory wire-hole in the back, top of the rear cab, which had a wire for the third brakelight assembly running through it, as well as several holes (10 of them I believe) for all of the studs coming off of the 3rd brakelight assembly itself.   I sealed all of those holes with RTV/silicone as well.   I found it kind of odd, that none of those holes, were sealed with any kind of sealant by the factory - if there was any there, it wasn't very much.   That said, I've been out in heavy rain and have ran the truck through high-pressure car-washes a few times now and she has been 100% water-tight to this point.   I feel very confident in the repair, we'll see how it holds up.
