Tires with really odd tread damage, mainly on the inner half of the tread. Shearing?

[mrsilv04]

These tires are on a 2018 Silverado 1500 Crew 2WD with only 15,000 miles. It is a local truck. Truck was sold new at this dealership, and traded back in.

The damage is mainly on the driver's side tires. The tires appear to be OEM's for this unit, due to the low miles and the late 2017 production codes to match the truck being a 2018. The damage seemed to be more pronounced on the inner 1/2 of the tires, as shown in the first picture.

The body of the truck shows no signs of being driven on gravel roads, no chips in the paint at all on the lower edges on the body.

I'm stumped as to what causes damage like this. Is the truck 'dogtracking/crabbing' as it goes down the road? Some of the damage has left the rubber in "flaps", as if it has been cut on the underside. I don't know if this would be described as "shearing"? First picture is the front tire, second is the rear tire... both driver's side.

I was considering this truck to replace my 2004.... but I'm definitely not sure now.

That looks terrible I'm surprised they didnt replace the tires.

This is exactly why I always prefer to NOT see a new set of tires on a used vehicle. What is being hidden?

Agreed. I've seen the heel/toe wear... it looks like you took a belt sander to the tread blocks and puts angles on them..but I have never seen that flaking rubber issue before.. or at least not close to that bad.

I'd be inclined to think the tires are simply shot.. and you might not have a similar issue with replacements.

@CapriRacer might be able to shed some light on it?

My guess would be check alignment. put on new tires properly inflated.. and probably have minimal or no issues.

Those are fairly old OE tires.. that we have no idea the life they lived.

Looks like Chunking - but its odd for it to be on only half the tire. Usually caused by running too low of air pressure or running too hot.

Could be a combination of things - like bad camber + too much load + too little air pressure, but having it on one side of the truck complicates that theory also?

The yellow dashed line is the center of the tread. Clearly the majority of the damage is to the inside half of the tread.
The pink circles show areas where the tread looks like it had a razor blade run underneath of it, and left the tread as a thin flap.
Yes, these tires are ruined... but will this happen again to the next set?

Have the alignment checked. Looks like the rear end housing could be bent.

Looks like it was rubbing on the frame or suspension in tight turns.

I would be shocked if the shock was fully operational.
Probably something more that's causing it.

I would guess it was a work truck at a rock quarry or something driven on rock rubble roads. Our plant trucks did this, although to a lesser extent, being driven on crushed rock roads.

 

[CKN]

Rubbing against something on full turns.

 

[Fabulous50s]

Both LF and LR tires are like this?

I'd honestly guess some road condition caused this. Such as a road which had lots of sharp shale or something.

If a tread compound defect id imagine it would be across the entire tread and not localized to the inners on the same side.

Chunking from gravel looks like this but much milder. I think this was a quarry truck

Old tires chunk easily. What's the date code?

 

[meep]

Off pavement use with a toe-out issue?

You could do a cheap measurement left to right, forward to rear, and perhaps diagonally to confirm the tires are square, or at least trapezoidal (front and rear track may be different widths) to the vehicle.

 

[mrsilv04]

Here's a picture of the truck in question. I highly doubt it was any sort of a 'quarry truck', or it spent its entire life of 15,000 miles (over 6 years) all on gravel roads. Gravel or unpaved roads are a rarity in this part of the state, and this truck clearly didn't stray too far from home... ever. Plus, it is a 2 wheel drive truck.

This truck has "old guy" written all over it. That's why I'm struggling with why the tires are so chewed up.

It has to be a mechanical issue of some sort. But what?

Tires appear to be the originals to the truck. Late 2017 date code on a 2018 model truck with 15,000 miles on it.

 

[dumkid]

Mechanical issues will usually cause cupping/feathering or unevenly worn tires

I don't know how a garage queen gets chunky tires.

Where's Capriracer

 

[Fabulous50s]

I'd buy it, throw new tires on it and move on. I'd say age and cheap OEM tires coming apart.

Alignment and other mechanical issues of a vehicle doesn't do that to tires, the tires themselves are the problem.

 

[CapriRacer]

I've seen this on a couple of OE tires that were used on a very rough road surface. It's a combination of a marginal tread compound and the rough road surface.

We see this a lot on tires thst spend too much time on rough concrete road surfaces. Such surfaces are common in the Caribbean… not the standard concrete highways and roads on the USA.

I suspect this truck spent time on primitive concrete roads.

I posted this on another thread. I see tons of these newer Chevy trucks going down the highway with tons of negative camber in the front end. Might have some suspension issues.
