So they said it was road damage....

Tire shop (Big O) chalked this up to hitting something sharp.

On the inside, sure, kinda looks like it:



On the outside it sure doesn't! Tear is smaller on the outside too.



I'll admit, I'm a bit perplexed by this. I've never seen a tire failure like this before. The tire is relatively new, on the truck 6 months, date code around 2 years ago if I remember correctly. Tire is a Cooper Discoverer RTX - one they make for Big O.

No way that was a cut from something sharp in the road. That is a pressure failure. I would bet the damage is from a hard, blunt impact damaging the cords - who knows when - and then the heat cycling in use and tire pressure eventually caused the failure.

Cooper just lost me for life - Big O too. I don't like being BS'ed even when I know why they do it and have some sympathy for them.

 

One bad tire out of millions produced and you walk away? Must be a hard man to please in life. Shit happens.

 

The didn't stand up for their product. The grudge is over being blown off, not over the odd bad apple in millions.

I'm not that hard to please, I just won't be BS'ed. Ever.

 

Why did you get rid of the stock tires?

 

Give him hell he has only posted twice. Way to go champ!

 

Truck is a 2018, I put a lot of miles on it. Lots of curvy roads to and from my workplace then, 150 miles a week on that and tires tend wear fast. The Generals I had after the stock tires lasted a bit better. Coopers are the third set.

 

Eh, a 6 month old tire looking like a 30 year old tire would give me pause also. Hell, a 30 year old decent tires doesn't look that bad unless it's been collecting water and skeeters in the sun for 20 of those years. Son is a chemist, the stuff that makes rubber flexible, pliable, and not weather check are what costs money. Guess where companies cut costs the easiest? Yep, the expensive stuff in the formula, just a bit less in each one makes the numbers go up.

Heck, I have some almost 30 year old tires still on a vehicle that look 10 times better then that. Yeah, yeah, I need to replace them but after seeing even expensive Michelins weather check like crazy by 6 years and out of the sun 99% of the time, I'm convinced it's more the low quality compounds in new rubber tires that cause failure and not age. [like the manufacturers claim]

Ford and firestone started the whole 6 years and replace tire mess and that was both cheapened compounds and rims that were so porous they would leak air thru the aluminum. [ford aluminum rims had a bad rep for that around that time, owned some myself] Yes, they failed due to overheating and low pressure but no one wanted to admit the real issue was junky manufacturing processes and ''good enough to ship'' attitudes.

[PS, SUV's are not sports cars either]

 

Heheh.... that's ok. Second post is a buncha bitching about a popular brand, so it wasn't a totally unreasonable reaction

But thanks

 

So it's not possible you ran over something to cause this? It's 100% a tire failure?

 

It has nothing to do with post count. It's a pretty extreme reaction to rule out a quality tire brand for a single failure that is not solely attributable to poor production.

 

Could have been caused by a bad wheel from Toyota.

 

Sure looks like a cut to me tires fault for running over some thing sharp.

 

I don't meant to discredit your experience but these kind of impacts, if they result in broken cords, will be very apparent as the tire will be out of round in a way as subtle as to cause a balance issue or as obvious that the tire is visibly lumpy. It's very likely a puncture/tear from a piece of debris

 

Looks like it could be a rock puncture.
Is it a Passenger rated tire?

 

I'd go with a clamp on style wheel weight.

 

I was thinking a bolt in the road, something like that. Even a zinc clamp on is pretty soft except for the steel clip.

 

Could be, but I don't recall hitting any rocks that hard. I do drive weekly on 15 miles of dirt road with lots of rocks, but I'm that guy driving slow. I tend to think it would be a small hard object on the freeway that I might not notice.

Its a truck/SUV tire, though perhaps not an AT rated tire.

 

i've had two Cooper at34s do the same thing FWIW, nothing that could be found to damage them and no Offroad use but splits right between the treads none the less

 

No, I do understand that it is likely caused by something I ran over. Its about lousy customer service - basically I have to figure it out for myself and show up here so you guys can straighten out my attitude - the vendor and manufacturer both had the opportunity to keep me from getting pissed off at them and they both blew it.

Probably all vendors and all manufacturers would do no better - I think we all understand that. Just sucks to get it proven so we show up and bitch for a while before forgetting it. You guys just have the misfortune of having to listen

 

@eating raoul - was there no road hazzard warranty offered ?
