    We were on the last 200 miles of the 1800 mile trip when BAM..flap.flap.flap. We had a blow out on our trailer tire.

    The DW (who was driving) handled it very well and was able to pull over with little difficulty.

    When I went back to check it out I noticed that the tread was blown open and starting to separate from the tire. The steal belts were broken and sticking out of the tire.

    So we replaced it and came on home.

    The trailer is a New-2-US 1998 Skamper and this was only our third trip. In fact, the force on the trailer was so violent that one of the hinges on the cabinets in the camper broke.

    The tire had plenty of tread left on it, and I had checked the inflation before we left (50 psi as written on the tire), so I am not sure what went wrong.

    It does say "for trailer use only" which I don't understand. Does that mean that it is an inferior tire?

    Should I be concerned about the other tires (driver’s side and spare)?

    Thanks for your input,

    Hi JustUs.
    We also had a tire blow out in the same manner a few weeks ago.

    Here is what I've learned, if anyone disagrees or wants to add anything..i'm open to suggestion.
    1. Tread remaining. Can't go by it. Really, we will never have as many miles as a car and will not likely every really wear out the tread.
    2. Why did it fail? Probably was dry rotting in the sidewall area during the "off season". We did not know how old our tires were on our used PU so I kept checking them closely looking for small cracks,etc.
    3. Checking inflation is a good thing to do. That'll help on your new tire/s.
    4. "trailer use only" is normal. Doesn't mean bad. Just means that it is designed especially for trailers...not for car / light truck use. Check your owners manual just to be sure that the right size and load rating tires were on your PU. Our load rating for ours is a "C".
    5. I would recommend replacing the driver's side asap assuming it is the same age as the 1 that blew.
    6. I did not replace my spare although I probably should. It is inflated properly and I've looked at it closely...can't see any cracks, etc. I'm hoping that it would last a few miles if needed.

    If anyone has suggestions as to the best policy for the "off season" to keep tires in good shape, I'd appreciate it.

    The sun is a tires worst enemy. If a trailer sits in 1 spot and the same part of the tire is exposed to the sun, the exposed part of the tire will become much weaker over time.

    A trailer parked east/west will have 1 tire exposed to the sun for many hours every day and a trailer parked north/south will have both tires exposed for only a couple of hours each day.

    I've had implement tires blow on equipment just sitting in the yard because they became weak over time from exposure and the heating of the day caused them to blow.

    If you have a cover on your spare tire it is probably good. The spare on my Bonair has never been used and looks like it is new.

    The amount of tread on a trailer tires is meaningless. Age and UV exposure kill tires.

    Trailer use only means that it is specially designed for the different stresses a trailer tire faces. Never put standard tires on a trailer, only ST (Special Trailer) rated. Nothing at all inferior about it, it means it was designed for that use.

    Replace all three tires.

    I'd say the first cause of a blow-out while tooling on down the road is under-inflation. ST (Special Tire) bias trailer tires get real hot, real fast, as the under-inflated tire will excessively flex in the sidewall.

    Of course, you don't have to be a tire expert to know when a tire is getting tread worn and getting that "balding" look. But as already posted, it's those good looking (but bad) tires that are the concern. I have a friend whose son-in-law works for a large tire distrubitor in this area and he says tires can deteriorate with age just sitting in the warehouse and he would'nt trust any un-used tire over five years of age. As for me, I don't trust my popup trailer tires that are over 3 years old, reagardless of how good they look.

    The other major factor with tires going bad has to do with "dry rot" and this has to do, in part, of how the trailer is stored. It's been my experience in this regard that trailer tires will go bad sitting on the bare ground. When the trailer is going to be sitting for a time where it's on bare ground, need to put something under the tire, like a block of wood or one of those patio stones.

    So buying tire covers is a good idea for use while the camper is stored outside it sounds like. Would just covering them with a plastic tarp do enough to keep UV from breaking down the tires?

    Sure, anything that will block the sun's rays from hitting the tires will help.

    You cannot depend on your spare even if it is covered. Mine was covered and it blew two miles down the road just after I put it on from blow out #1.

    Note that I said blocking UV rays helps ... it doesn't prevent a tire from deteriorating from age. Even if a tire has always been covered, properly inflated, etc., but is old, you can't assume it's safe.

    UV is not the only thing that causes deterioration. Simple exposure to air is just as big a culprit.

    It's hard to bring yourself to throw out a tire that looks good, but may be 6, 8, 10, or more years old. It would be a lot harder to look at the safety issues and possible damage that could be caused by putting it on your PUP and setting off at 65 mph!

    I'm of the opinion ... (please note that I said OPINION!), that it's better to let the tire be exposed to the the wind and the rain and the sun's rays rather than being "cooked" under a vinyl cover. Anyway, my spares are exposed ... and I have two! One mounted on the rear and the other on the trailer tounge.

    Now if I were to keep a spare under a vinyl cover, I would wrap the top of the spare tire with aluminum wrap and then put the cover over both. Have you ever seen a tire's imprint on the top of a cover after it's been there awhile?

    If your tires say 50 pounds...thats 50 pounds MAX. Remember when your towing the heat will build up, so that 50 gets alot higher when the heat is on. I run mine at 40 here in Texas because the roads will get hot, and the pressure will rise in the tire. Even my dealer told me NOT to put 50 in the tire but keep it around 40 because of heat build up in the tires.

    Yes ... BUT ... the tire manufacturer already had taken that into consideration. Remember their admonishment ... "inflate the tire cold".

    That's 50 psi max COLD my friend. The tire manufacturers build the heat in so you are more than likely running 20% short if only filling to 40 psi. My contention is you were given bad advice. That's like saying that because I am in MN and it is cooler in the fall that I should fill 50 psi tires to 60 to compensate for the extra coolness.

    HI always inflat you tires to the proper psi.you always check your tires when there cold and if the are to be inflated to 35 or 50 thats were you inflat them the tire manutfacture has taken it in to consideration.just remember the camper sometimes will set for sometime,before being used agin.

    Ours lost five pounds of pressure over 4 days in the cold mountains, we had to re-inflate before we left, we brought them back up to 80 psi with our battery operated compressor and drove it down the mountain into a heat wave, and nothing blew.

    Except our minds, we thought we must have been camping on a different planet!

    We bought our pup in mid-May. My husband mentioned wanting to get the tires checked. They looked good (tread was good), but he's one for inspecting detail. Unfortunately, our F150 required some attention before we could use it to pull our pup on its first real trip. Let's just say it had something to do with the rear axle, leaking seals, and brakes. I understand it was a pretty significant repair. We get the truck back on Friday and left Saturday on our trip -- Ohio to Gatlinburg.

    So we're back. Preparing for our second trip and he brings up the tires again. He takes off for the tire shop and returned with brand new tires. Why? Come to find out the tires were original -- 20 years old. They don't even make that brand anymore. The inner-side of the tire walls were cracked all the way around. We're thanking God that we got there and back without a major blow-out.

    The husband tells me that we'll be pulling the tires before winter and storing them in the garage (leaving the camper to sit on jacks). That'll prevent the tires from deforming or rotting. The 20-year-old spare, however, passed inspection.

    Here's something to consider ... there are several tire shops that have now gone to nitrogen instead of compressed air for inflating tires. There's lots of claims being made about nitrogen, but the most important here is that nitrogen will not expand with heat like they do with compressed air.

    I've went over to the nitrogen with my TV ... the deal is they charged me $5.00 per tire and will maintain the tires for the life of them. Should I be someplace and develope a slow leak and have to add compressed air, when I get back they will purge the tire of the compressed air and re-fill with 100% nitrogen. The biggest draw for me to give it a try was all the reports of longer tire life. (we'll see!)
    They said they would do my camper tires, too! I'm still pondering that - but bias belted tires simply don't last as long as radials.

    Stay away from the Carlisle radial trailer tires. I'm new to pop-ups but have been pulling a boat for as long as I can remember. Do a google search on "Carlisle trailer tires" and you'll see what I mean. It will bring up a few fishing boards with discussions and horror stories about blow outs with relatively new carlisle tires. There was even talk for a while about a class action lawsuit but I don't know what ever became of it. Goodyear Marathons are the peoples choice for radial trailer tires for those interested.

    Carlisles used to be the cream of the crop in terms of trailer tires. Their quality has taken a nose-dive in recent years IMHO, and as witnessed by the thousands of sites that mention bad Carlisle tires. I've had them be a hit-or-miss quality. I had them on my tandem axle boat trailer, load range E's, and had one of the four that refused to hold air. The dealer insisted it was the rim, so they replaced the rim alone but I continued to have the issue. I eventually sold the boat and trailer, but still find them questionable at best.
