RE: Mission Load Max Radial crowned like a bias ply.

The one on the left is EXACTLY what mine looks like, though not as pronounced. I don't have any other tires of that brand to compare it to, but the promotional photos for the brand show a nice square flat profile. Finally got pictures but it looks like I need an external photo hosting site. Don't belong to one. Don't want to belong to one. So you're just going to have to use your imagination. The tire is dated 2004 but is still supple and has no weather checking. Still had 55PSI in it when I let the air out this afternoon. I only want to use it for a farm wagon, and a spare at that. Will only be inflated to 30-40PSI most likely. A tire that is bulged out as shown above is separated! It has failed!! It's just that the belt is still trying to hold it together. Using the tire further will cause it to come apart - SUDDENLY and doing damage in the process!! DO NOT USE A TIRE THAT LOOKS LIKE THAT!!

RE: PSI of LT tire after upgrading from P rated tire

This information is actually uniform across all tires so we do not have our own chart. I did google it for you though and found this link: The chart is always a good place to start. From there you can fine tune psi that gives you the best handling and best long term tire wear for a empty truck and a fully loaded truck. CAUTION: That chart is for ST type tires - and this thread is in "Tow Vehicles"!!

RE: PSI of LT tire after upgrading from P rated tire

Take a chill pill way too much worrying inflate to rated tire pressure listed on sidewall of tire. Totally wrong answer!! The correct answer is: If the numbers in the size are all the same, in order to carry the same load as a P type tire does, an LT type tire has to use 15 psi more (more or less. Precision isn't necessary here!)

RE: Tires & DOT

No written, just a lengthy conversation with a Sailun rep. sure its a guess .But when a tire blows ,there is no mistake what happened , its loud ,and obvious. …… First, the only thing you can tell when a tire blows out is that it lost air. One can NOT tell from just that bit of information whether it was a road hazard or a structural failure. Second, "tire reps" is not distinct enough to tell if the guy has any expertise or not. Very few people have the knowledge and experience to diagnose a tire failure - not sales guys, not phone consultants. So what is your point, are you saying I don't know if it was a blow out or not. I never said the tire rep said anything about the cause of why I lost the tire. I pretty much came to my own conclusion, and I repeat its a guess. Tire stayed together, no idea how far it went without air, I don't think it was that far. I was traveling at 65 mph. I look frequently in my mirrors, but IMO it was not a sudden loss of air, but as said its just guessing. If it was a sudden blowout it was a quiet one. If it was a defect tire it took two years to raise its ugly head . I'm getting lots of contradiction. First you say a blow out is loud and obnoxious, then you said you didn't know how long it had no air. And if you came to your own conclusion, what was it? Are you saying a loud obnoxious blow out has a specific cause? If so, what do you think that is?

RE: Tires & DOT

Local Sailun dealer has 4 DOT 3919 tires. Freshest he can get for now. eBay merchant can guarantee 2119. 3919 is still 8 months old and the warranty applies to manufacture date not date of installation. Nuh, uh!! Sailun's warranty starts from the date of purchase. All Sailun tire lines are warranted against failures due to defects in workmanship & materials for the life of the original tread, or 5 years from the date or purchase, (whichever occurs first).

RE: Mission Load Max Radial crowned like a bias ply.

Bought three old trailer tires on rims to use on an OFFROAD firewood trailer. All kept in a dark building, no dry rot or cracking. I am aware these tires are beyond their useful life for road use. It's hard to find decent 15" tires to fit on implement rims these days without paying the long buck for actual implement tires. The two Carlisles have a nice flat profile on the tread like I've come to expect from a radial. The third, a 2004 "Mission Load Max Radial" has the profile of a bias tire. Is that normal? Am I looking at a slipped belt on this one? It's perfectly round, and I'd expect it to be egg-shaped if a belt slipped. That sounds like a tread separation - what you are calling a slipped belt - and, No!, it could be so old the ENTIRE belt has separated from the rest of the tire. Do not use that tire!

RE: Tires & DOT

Not "implying" anything just repeating what the tech at SimpleTire sent me in an email... Hello, Thank you for your email to SimpleTire. Unfortunately, we are unable to provide the details of DOT to the customers because warehouse won't be able to check the dates on Individual tires and we stock tires which are from 3 months to 4 years old from the date of manufacturing, which is within the industry standard and considered as new Tires. Please do let us know if you need any more information and we will be more than happy to help you out. Regards, Vivek Support Team SimpleTire Thanks for that - but at the risk of being pedantic, he said "industry standard", you said "legal". It's true that the industry thinks 4 year old tires are OK to sell as new (Heck, I think the industry thinks it's 6 years!), but to my knowledge there is no law or regulation.

RE: Tires & DOT

…… They are legal to sell as "new" up to four years after they are dated. …… That seems to imply that there is a law that says that they can NOT sell tires as "new" if they are older than 4 years - and that would be a new one for me. Can you cite a regulation? …… I replace these tires every five years per DOT Code. …… I am hoping you mean that you use the tire's TIN (Tire Identification Number) aka DOT code, and not the regulations issued by the DOT. Because if it is the latter, I would like to know where I can find that regulation.

RE: Front Tire alignment failure

Except they swapped tires left to right. That should have reversed the direction of the pull if it was tires. The pull didn't change, so the problem lies somewhere else. I'm going for draggy brake.

RE: Unusual tire wear

3rd try It's a little hard to tell how much wear there is, but this looks like the base compound being exposed. Nothing to worry about, except that you are very near to needing to replace that tire. Background: When a tire is made, the tread rubber is extruded in a slab, cut to length, then wrapped around the uncured tire and the ends of the tread slab are spliced together to form a smooth, continuous looking tread. (Note: The tread splice is cut at about a 45° angle) It is common for the tread slab to be 2 extrusions in one: A Cap Tread (made of a good wearing rubber) over top of a Base Tread (made of a cooler running, but poorer wearing compound.) The idea is that the base shouldn't be exposed, but if it is, it will be at the end of the treadlife and not matter in the big scheme of things. Edit: Apparently, I was lucky enough to be able to see the photo before it disappeared.

RE: Unusual tire wear

Thank you for the comment - very interesting. My take-away from that is to inflate the tires substantially more than the chart and then rotate the tires from front to back. It is still surprising to me that while all of six tires measure 13/32s on all four tread grooves, the steer tires have just the edges of the outer tread significantly scrubbed off, particularly the left outer on one and the right inner on the other. Perhaps those 2 long drive days fighting a very strong cross wind did that damage. Possible. But your first post talked about the wear revealing a different rubber compound. Someone mentioned posting a photo - and that is a good idea. But I can tell you that some tire manufacturers use what is called a "Sidewall over Tread". This is where the sidewall is applied last in the building process. When the tire wears, the sidewall will appear as a small sliver on the outermost rib. Perhaps that is what you are seeing?

RE: Unusual tire wear

Generally speaking, over-inflation causes the center of the tire to wear and under-inflation the outside edges. The way to get the proper inflation is to weigh the axles, preferably the individual corners. This should get you in the ballpark of the proper tire pressures. If both the inside and outside edges of the tire are worn, under-inflation is the problem. If just one edge is wearing, it is most likely an alignment problem. All accurate info. What perplexes me (and may be of use to others) is that I weighed each wheel, and then used the charts for air pressure for that size tire. In fact I actually increased the air pressure over what the charts recommended but the tires still wore much faster on the outer treads. My guess: the chart was wrong or this particular tire construction makes the outer tread wear down prematurely First, with regard to evenness of tire wear vs inflation pressure, there are forces at work that are stronger. For example, steer tires tend to wear in the shoulders and drive tires tend to wear in the center. This effect is on the order of 3 times stronger than the effect inflation pressure has. And lastly, the charts aren't wrong. Those charts are generic in nature. That is, they are published by a tire standardizing organization and are used by EVERY tire manufacturer when designing tires! Plus, they are MINIMUMS, not recommendations. You should be inflating the tire MORE than what the actual weight/chart says. In fact most vehicle manufacturers add about 15% to the max load to get the specified inflation pressure - and the tire manufacturers know that, so they take that into account when designing tires. In theory, then, if you used the actual weights and the chart to set the tire pressures, the tires are going to wear like they are underinflated - and still, the effect wheel position has will be overwhelming.

RE: Tire flat spots

Without a doubt, the tires are flatspotted - the question is, are the flatspots bad enough to cause a problem. Flat spotting is a function of how much load is on the tires vs how much inflation pressure, the length of time, and the temperature. Unless the tires are resting in a contoured cradle, it doesn't matter what surface the tires are resting on. The only way to be sure if it is a problem is to drive on them - and if they are a problem, will the flatspots work themselves out? Maybe. So for those who want to know how to prevent (minimize?) flatspots, taking the load off the tires is the best - like removing the tires from the vehicle. Over inflating them is helpful. (You can over inflate tires by 20 psi without fear of explosion, but don't operate the tires at that pressure!) Moving the vehicle periodically is also helpful (that is resting the tires in a different spot - even 3 inches is enough!)

RE: LT tires on your TT? Let the fight begin

More fuel for the fire: 1) People who replaced their ST tires with LT tires increased the effective load carrying capacity .... because: 2) The load carrying capacity of ST tires is calculated differently than LT tires. The result is that ST tires are rated to carry about 20% more load, but at a lower speed.

RE: New Trailer Tires - And THANKS

I don’t do Facebook. I have done several searches and not one non road hazard has been mentioned. So as a friend tells me please prove with pics and testimony these you mention are NOT roD hazard. To be honest I can’t believe there have been none my self but I have seen nothing along with CapriRacer. I have the pics and they are not road hazard issues they were tire failure themselves as the entire tread has separated from the sidewall. I have posts from facebook and instagram. I would post the pics here but not sure how to from my phone. Can I send them here through a message? When the tread separates from the sidewall, that is a "run flat" - usually caused by a puncture. I've examined thousands of those and 90% of the time I could find the puncture. The other 10% I speculated that the puncture was in the area of the damage caused after all the air was let out - and this was confirmed by Rex Grogan, a noted tire forensics analyst who published a chart showing a study of where punctures occurred in a tire - and 10% were in the junction between the tread and the sidewall. The failure mode of interest is a belt-leaving-belt-separation, as described in the Tire Conditions Manual published by the Tire Industry Association. Tire Conditions Manual This failure is far and away the most common non-road-hazard related failure mode. It is characterized by the tread and top belt detaching in whole or in part, leaving the rest of the casing intact and frequently the tire stays inflated. If anyone has a photo has one of those in a Goodyear Endurance, it would be of great interest. But if someone only has a tread/sidewall separation, that is NOT of interest as that is caused by a road hazard. To date, I have not seen nor heard of any.

RE: New Trailer Tires - And THANKS

Just for my own curiosity what does your data show on the new Carlisle Radial Trial HD? I had these on the previous trailer for about a year without any issues and have not notice any failures mentioned on the forums so just wondering if these tires are better now too. Rob Sorry, but I don't any data. First, my experience was with a major tire manufacturer and we only tracked RETURNS for THAT manufacturer. I retired 7 years ago, so not only do I not have current data on ANY current tire, I don't have ANY data at all. What I have been doing is looking at reports on this and other forums and the one that stands out is the Goodyear Endurance. It's the only one I know of where I can track when it was introduced AND there have been no reports of failures. I am sure that eventually there will be a failure reported because consumers don't know how to discern the difference between a road hazard related failure and a failure caused by the design. (Please note: My experience says that by far and away, it is the design - that is, the materials used and where they are placed - that results in failures and not defects - things that aren't supposed to be there and things that aren't there that are supposed to be.)

RE: New Trailer Tires - And THANKS

Thanks for the reply! You actually felt the tire was credible last year. I have saved some of your comments from the past for the nay sayers! :B First, structural tire failures in the winter months are almost non-existent. The last month where you might see a few is October. They start up again in May. So, yes, I made that prediction in October of 2019 after the season was over. Nothing magical. Just the facts.

RE: New Trailer Tires - And THANKS

At least someone here has decided the ENDURANCE is a credible tire now that it has made it to three full years on the market with stellar results. :B That would be me. Former tire engineer with a major manufacturer who tracked returns and developed algorithms to predict return rates. My experience said that after 2 years in the market, you could predict the return rate for structural failures - which peaked in the third or fourth year. Since no one has reported a Goodyear Endurance ST tire failure in 3 years (They entered the market in the fall of 2016), my prediction is that there will not be any design failures until the tires age out. (We don't know when that will be.) Please note: That even the best designed tire can suffer from road hazards (punctures and impacts) and those types of failures are difficult for the average person to diagnose. Ergo, people will report tire failures and blame it on the make/model tire even if the cause is not tied to the make/model. Been there, done that! That's why we examined every reported failure for root cause.

RE: Goodyear Endurance tires?

The sticker on the side of the camper says GAWR of front and rear are 4400 pounds each. It says the rims are 15x6.0JJ. Does any of this indicate whether or not my rims can handle 80psi? No! It does NOT indicate that. Rims are not required to be marked with max load or max inflation. Some are, and some aren't. - BUT - It is my understanding that it isn't pressure that causes wheels to fail- it is load. So the wheel manufacturers figure out what the max possible loads would be for a given wheel (based on rim width!) and test to that. That should also mean that the wheel can handle the max pressure provided the tire is properly sized for the wheel.
