One thing in this poll that jumped out at me was that most failures were at 65 psi. Fewer failed when pressure was lower. I am assuming most of these tires are load range D, maybe maximum pressure is not the best way to go?

It's true that the most failures (28) are at 65 lbs, but that only indicates that is the most common pressure as it is the recommended pressure for D tires. But there are 10 failures below 65 and only 2 above. And pressure need not be the root cause of tire failure, but can be a contributing cause.

Since some people have C and E tires, even 65 could be under inflation, but the poll does not give us that answer.

The root cause can be lousy tires which fail either on their own, or even sooner with other contributing causes, one of which would probably be under inflation.

Pheonix,

For the purpose of your survey, does normal pressure mean at the max cold pressure marked on the tire or just whatever pressure is normally used by that individual?
I have looked at a few manufacturer's inflation charts and I do not see any pressure that is indicated as "normal" or recommended. They only give a range of pressures and loads at those pressures.

Gene,

My thought was maybe a softer slightly under inflated tire might be less damaged if it has some give upon impact.

Alan

Alan, a slightly under inflated tire is a bit more likely to blow or suffer tread separation. I doubt the relative and perhaps insignificant softness of an under inflated tire will reduce damage. An unmounted tire is not "soft" either. It would take substantial over inflation to make a tire rock hard as there is significant safety margins built into them.

The nominal recommendations for the 15" OEM D tires on many recent Airstreams is a generalization for a fully loaded trailer. An empty trailer would have a "normal" pressure somewhat less, but I doubt that accomplishes anything. A higher pressure may wear the tire slightly more in the center, but who tows an empty trailer very often? Different models may have slightly different "normals".

In this poll, "normal pressure" referred to whatever PSI was normally run. So, the other questions regarding whether the tires that failed were at "normal pressure" or a higher or lower pressure were only referring to whether the tire pressure was higher or lower than that to which the tire was "normally" inflated.

Regarding underinflation, softer tires flex more and generate heat. In the desert southwest, underinflation is one of the major causes of tread separation and blowouts. (Remember the Ford Explorer tire problems from several years ago?)

Carlisle load range E

I recently completed the poll. I replaced my orginial marathons with Carlisle load range e. I had two of them fail without damage to the trailer. Third tire threw the tread and did thousands of dollars worth of damage to my trailer.
While having the tire replaced at Discount Tire and having a claim filed against Carlisle I also pulled the fourth tire which looked really weird bulging all around the middle of the tire and brought it to Discount. Where I was told that this tire was ready to separate. I also had a pressure monitor system in place when all of this happened but had no warning soon enough to avoid the failure. The tire that did all of the damage had severed the sensor from the tire stem and was still deflating when I walked back to see the damage.
Carlisle ran me thru the hoops, pictures, estimates the whole nine yards. Than returned with "The tire was out of the two year warranty" and it showed signs of wear from axle problem. I do not know where they saw the "signs" as all the tread was gone. (Discount had sent the tire to them)
Bottom line they were not interested in my problems.
I had included in the package of info I sent them all the other failures where Discount had replaced the damaged tires. ( I had bought the tire failure replacement warranty that Discount offers)
I had all the tires at 75 or 80 pounds of pressure and monitored this also.
Bottom line, I will never buy another Carlisle product.

My tire "failure" was identified before the tire could really have done any damage. I identified the failing tire with RoadForce balance measurements before the tire fell apart.

Note: In investigating 16-inch tire failures, it appears that the two 16-inch failures reported in this poll were actually 15-inch, 225/75x15, Goodyear Marathon tires. One was a blowout with tread separation, and the other was a tire stem failure.

Therefore, as of 07/05/12, there have been NO 16-INCH TIRE FAILURES reported in this poll.

If you do a follow up poll, it would be interesting to add "what brand of tires are on my trailer now".

From following the tire posts on this forum, the people that have stayed with 15-inch wheels seem to be switching to Michelin LTX M/S, "XL" rated tires in 235/75x15, which appear to be similar to the old Load Range C tires with 50 psi max inflation.

Of the people that have switched to 16-inch wheels, most seem to be buying Michelin LTX

From following the tires posts on this forum, the people that stayed with 15-inch wheels seem to be switching to Michelin LTX M/S, "XL" rated tires in size 235/75x15, which appear to be the same as Load Range C tires, with max pressure of 50 psi.

Of those who switched to 16-inch wheels, most seem to buy Michelin LTX M/S, Load Range E tires in size 225/75x16, which have max pressure of 80 psi. I estimate about half are running 80 psi, and others appear to be using somewhere between 65 and 72 psi. I think the LTX M/S is popular because of price and the fact that Airstream offers these as a factory option.

A few have switched to Michelin XPS Ribs in Load Range E, size 225/75x16; although, they are in the minority and appear to be mostly 19- or 20-foot Airstreams with single axles. Users are so few, that I am unsure what pressures they are running, although I do recall a couple saying they use 80 psi (including me).

Even fewer have switched to BF Goodrich Commercial T/As in Load Range E, size 225/75x16, which are very similar to XPS Ribs and are all-steel construction, too.

Regarding those that switched to Michelins, I do not recall anyone reporting subsequent tire failures; although, I may have missed the posting. If there were any Michelin failures, they have pretty much gone under the RADAR.

I was planning to do another poll for 16-inch wheels and tires, but there are probably too few people that have switched to provide a significant amount of data. Also, I hope that poll would be really boring, with hardly any failures.

The BBS software used for this site is not very conducive to polls with a lot of questions, and construction is very time consuming. Also, you pretty much have to get it right the first time; as the poll cannot be corrected or updated easily. I suspect that a moderator may be able to edit them, but I'm not sure they would want to devote the time to trying to fix problems.

Perhaps, later in the year, enough people will have switched to make the creation of a new poll worthwhile. There appears to be a lot of tire failures this summer as people hit the road, so we can revisit this subject closer to the holidays.

Thanks for the inquiry...

Phoenix, first, thanks for keeping this going and providing the analysis for those who don't want to read the whole poll.

I have this vague memory of someone having a problem with a Michelin a couple of years ago, but I'm unsure. I can't remember what the problem was either. I had a Michelin on the Safari pick up a screw and drove thousands on miles with a very, very slow leak until I finally got it fixed, but that's not a tire failure problem.

I had to post "NO" failures on the ST tires because I only towed the trailer from the dealer in Los Angeles to Phoenix (about 450 miles). At that point in time, the trailer was about three months old from build completion date.

Having started reading the "tire issues" threads on this forum before taking delivery of the trailer, I was aware of the "ST" tires issues and immediately changed all five tires to Michelin LTX (P) 235/75R15 XL on the factory 15" wheels to preclude the chance of the notorious "ST" tire issues.

Since the tire switch, I have only towed the unit about 150 miles for two trips across the CAT scales. The trailer is perhaps a quarter inch higher off the ground.

I have been sort of, kind of following this thread on tires. For the time being I am satisfied with the relatiely new GYM- 15"ers that came along with our, new to us, '01 Excella. Drove them hard last summer in hot weather with no problems. But I will keep an eye on them. Thinking ahead when they are due for replacement I've been paying attention to threads like this one. I like the wheels on the trailer ( original Alcoa style) and don't have any interest in upping to 16".

My question is: Among those that have changed tires and stayed in the 15" wheels have you found that the weight capacity is adaquat for safely handling a 30' AS ?????

Thanks all, see ya on the road sometime.
