Good catch !

My dually has had this slice since I purchased the truck over two years and 10k miles ago. This is a front tire supporting a 6.7l diesel engine.

I have a new set of Michelins ready to replace this tire and the rest of the tires; just can't get this tire to "give up the ghost".

Why would you deliberately chance your life and the lives of the motoring public with a front tire like that? And posting it on a public forum? Not to mention it is an out of service and towable fix it ticket.

To the original poster I would 100% replace the tire. Sidewall slices or cracks are nothing to mess with.

Aint never seen a 10 ply vehicle tire do that under any circumstance. I have seen durability with Nittos in the past.

I wouldnt run a tire with a crack like this.. IMO its reckless to the motoring public.
esp on a tow vehicle.

The damage to the tire is a cut. I suspect the cut may have happened during off road border crossing events.

When I discovered the cut, I did an observation and began to closely monitor the tire. Monitoring included pressure changes in company with the other five tires. Additionally, I immediately purchased six new OEM takeoffs that are at the ready to install.

Two years of testing/ monitoring, I am drawing my own conclusions on how different damages to tires may or may not impact the life and/or drive ability of the tire.

Others will draw their conclusions.

Sure, you never know, until you know. Of course sidewall issues can be grave. Those LTXs are a departure from the aggressive Nittos!

Nope me neither. One big advantage with a DRW is if you have a flat or blowout, you can normally limp on out with 5 tires, perhaps with limited speed while loading to get to a save place.

Lots of reckless things we have accepted as fact, only to find out critical thinking and analysis was never performed.

We should start a list of things considered reckless that ended up being erroneous.

• Eggs are bad for you
• Red meat is bad for you
• Grains are good for you
• 15 year old Michelin Defender 10 ply tires are more dangerous to use than 2026 manufactured Chinese 10 ply tires
• Bulls hate the color red (bulls are colorblind)
• Mother birds will abandon babies if you touch the babies
• The earth is flat
• Girls are not genetically bad at math

One only needs to analyze the marshmallow test to know many published standards, facts, etc--- are misinterpreted.

I am not a fan of all terrain tires for what I use trucks for. I am a huge fan of Michelin 10 ply tires, and would only consider Michelin, Bridgestone (maybe Firestone), and Continental for 10 ply tires.

Having run michelin tires on 3/4 and one ton trucks since the early 1990s, I have never once had a Michelin 10 ply tire ever fail.

Agreed. For me, the LTX AT2 tires have been very good, under very harsh conditions, long wearing.....close to 55K now and still have probably 10k left in tread depth...These last ones did not balance very well though.

Here's a max zoom picture, no idea if it's cleaner view? Don't see any bubble or feel any vibrations. Drove back on the freeway for about 20 mins before I notice the gash, didn't feel any issue.

The reason the cord is important is that there is a pressure gradient through the tire. Cord fabric tends to wick air pressure and if exposed, will give a higher pressure where it is not wanted, so it will blow off the sidewall.

What puzzles me is why you would think this is ok when there is an obvious sidewalk tear and you have a new set of good rubber just sitting ready to go?

My critical thinking and analysis is the risk is not worth it. I have first hand experience behind the wheel with a high pressure tire blowout and it is very ugly.

You ask a very valid question.

My question to you- what testing have you done to validate if a tire can in fact operate the same with or without the visible sidewall damage. Does the sidewall damage actually make the tire less reliable, the same reliable, or even more reliable?

When I picked up the truck from the salvage yard, I didn't catch the sidewall status. I drove IIRC about 2k miles, from the hottest humid climate in the USA to a very moderate summer climate. I monitored the tire pressures throughout the drive, and all tires performed the same as far as air pressure.

After discovering the sidewall, I went on the hunt for a new set of Michelin take offs. I wasn't driving the truck except to do work on the truck. What I started to observe, is the sidewall didn't display a single sign of tire dependability degrading... not one. I kept monitoring the tire, never once did any operational signs of degrading compared to the other fives tires arise.

So, I had to ask myself, is any damage to a sidewall a blank check to buy a replacement tire? Or should all tires with a sidewall issue be inspected, and a decision made on what to do.

I chalk it up to the "five" year and old stock tire manufacturing date. I have not seen testing that verifies, validates, or accredits that high quality older tires are a safety hazard. Not one. In fact, the NHTSA does not mandate tires be replaced based on age/ date of manufacture of a tire. Yet, tire shops preach the tire age issue endlessly.... the question is why????

I am in no way supporting the use of an unsafe tire--- not at all. At the same time, I am not going to blindly throw away a tire that can operate to manufacturer specifications, exclusively on information that doesn't include analyzation of the tire.

In the tire of subject here- the sidewall displays zero bulges that typically occur when an impact (pothole, curb, debris) breaks internal cords within the sidewall. The visible bubble is evidence that the tire's structural layers have already failed locally. Such damage is generally considered non-repairable and a precursor to potential catastrophic failure. I had no bulges, and over two years and 10k miles, not even the tiniest sign of a bulge has shown itself.

You are the one running the tire on a public road. Do you have any data that this tire is safe?

I would not run that. Not a chance i want to take.

I had the unfortunate incident of a crack much smaller and shallower than yours turn into a catastrophic event. I was lucky to come away unscathed. Any tire damage that is from the edge of the tread to the rim is not worth the risk.

Not to mention it is 100% illegal and tire has to be taken out of service under the FMCSA guidelines. This is your go to for regulations concerning your truck.

Even if not being used for interstate commerce (Hotshotting) it still falls under the threshold of over 10,000lb GVWR. And, depending on your state, it will be registered as a commercial vehicle as the default. If that is the case then your vehicle falls under the FMCSA
regulations.

The NHTSA is not a fair representation to highway safety. FMCSA is just for the fact it regulates real world day to day operations of commercial vehicles such as yours.

Another thing to consider is the unfortunate event you are involved in a collision.1st question the in insurance adjuster is going to ask is why was your vehicle being driven with that tire? Claim denied.

Would have thought the question you might have asked to better assess the tire would have been something along the lines of "are any cords exposed"?

Wonder is this truck's hitch was gooseneck or bumper pull?
