I have a 09 2501ss which came with Carlise tires, i had a bad vibration from mile 1, i took the tires off and put them on the balancer (i own a goodyear tire dealer), just to find the tires had anywhere between .060-.080" of runout, I called Carlise's warranty dept & they will not replace any tires unless the runout exceed .100, which is way too much, goodyear calls for max .040" anything more would cause ride disturbance, i replace all 5 tires with marathon & now it's smooth as silk, the way i see it, it's cheap insurance to pay for worry free traveling, anyone for a set of brand new carlise with 20 miles on them? One more thing, i check the bearings while i had the wheels off, guess what i found, china bearings, i replaced all of them at once with sku bearings, luckily that i did because two of the bearing cages were bend, this is a unit with 20miles on it.

I had a blowout last month, and when I got to discount tire, they told me the failure was because the factory used 50# valve stems in a 65# application, they were really flimsy, at at speed will bend over and crack, leacking all your air out, then boom...... replaced all stems and then fiinsished over 3,000 miles going at time 75mph with no ploblem from then on. all that damage to the coach becuase of a 50cent part

I won't argue that Marathons are better than Carlisles.
Probably much better but no one is immune...
here is a snip from my other trailer chat group.

When leaving the CMA festival in Nashville in early July, we had the rear drivers side tire blow out. It was a Goodyear Marathon with about 20k miles on it. It really blew-strings of metal belts and rubber.
Once settled there I was searching under the sink for something and realized I was seeing light in this usually dark place and I was seeing bushes and grass!! The blown tire had fractured the wheel well along the seam.

It can happen to the best of them
I almost forgot to mention, this happened on an Ultra Lite trailer that
was no where near max load per tire.

Have you ever looked in side of a Carlisle tire?

Just for inspection to see now China makes the tires.

We had two tire blow outs on our trip from Buffalo NY to Boston, Mass. on our 2002 25' Rockwood. One on the way there and one on the way back. I learned a lot about trailer tires that weekend. We are pretty new at this, the tires "looked" new so I didn't worry about them at all. It turns out the tires were 8 years old! Some major points about tire maintenance:
- Jack up the trailer to get the pressure off of the tires. Sitting idle is the worst situation for trailer tires. Putting tires up on boards to get off the concrete is not enough.
-Cover the tires to protect from damage from the sun. It was amazing how much newer the spare looked (protected by a wheel cover) compared to the other tires.
- Carlisle recommends replacing all of your tires after 3-5 years regardless of how "new" they look. It may seem like a sales ploy but it makes sense. The longer a trailer sits the more the tires sit with all of that weight on them.
-Inflation, check it often. We went on a two day trip. I set the tires to 50psi before we left. The day we left for home the temp outside jumped about 15 degrees. I checked the tires and they were at 55psi before we left! I backed them off to 48.5 psi to allow for expansion due to heating up while driving. Carlisle does not recommend this but I checked their chart of psi vs weight support and even with under inflation the tires will support the weight of our trailer and all the stuff in it.
-It probably wouldn't hurt to find a good armoral type coating to protect the tires from sun damage while out on trips. Or to just bring the wheel covers and throw them on while parked.

It's strange how we have to baby camper tires, but yet automotive tires in some cases do not even get washed when the car gets a bath.

Well it amazes me that in all of this discussion that there was no point made about towing speed. ST tires are only rated for 65 miles per hour. So, if you are towing in excess of this speed, don't be surprised if you have a blowout; especially if it is hot and the trip is long. Watch for under-inflation, over-loading, and excess speed.

That's strange, while we were at Myrtle Beach a week before that, one street over from us there was a 5th wheel that came in and had blew the right front tire, it had damaged the trim around the wheel well and the electric brake wiring as well as leaving black marks around the wheel well. I saw the tire in the back of the pick-up, It look like the seam where the tire was molded together split open.

Most tire failures on RV's are due to age and lack of constant use. RV's that have constant use keep the Juices (so to speak) flowing in the tire and the rubber stays pliable and lubricated. That's why automotive tires have less tendency to fail regardless of inflation pressures. When I used my RV constantly I never had a failure on a tire until the tires were replaced after 10 years of use. Now, I replace my tires every 5-6 years or if I see ANY evidence of deterioration (cracks along the bead, on the sidewall or between tread lines). If i see any of the above they all get replaced. I made that mistake once and had a tire failure on the unused spare I put on after it hung (covered) for 8 years on the back of the RV. I got cheap and paid for it in underbody RV damage and a destroyed wheel.

Tires on RV's are exposed to a completely different type of stress than those on an automobile. Just take a look at them if you stop in the middle of a tight turn. Stress to RV tires is more side to side and twisting motion. That is why you must use ST type tires and not automotive tires. The cord is designed and distributed differently (supposed to be). I suspect that cheaper RV tires (Chinese) are not always correctly manufactured and fail more often.

Underinflation is a tire killer. You can get away with 10% overinflation but never underinflation. Traveling from higher altitude to lower altitude can make a profound difference in tire inflation. Your tires should be checked and properly inflated ASAP after major altitude changes of 6-10K ft. Again, you can get away with the pressure increases that occur when increasing altitude but not the other way around. Add the fact that when you decrease altitude you also usually experience increased ambient temperatures and you have a recipe for failure at highway speeds.

Also a new member of the Blow Out Club

C rated Carlisle ST225/75R/15
65MPH
50 PSI cold checked prior to departure
Recent CAT scale "in limits" weight
1 year and 15 days old.

Changed it on the shoulder (shudder)

Lost the plastic trim around the wheels.
DENT in FRAME! (WTH do they make that out of? No wonder they DO NOT recommend frame hitches in the Ultra-Light series!)

Just a loud "Pop." No pull. (Just a feeling like we were passed by a truck)
I told DW that I thought a truck had blown a tire. Then I thought... What if its me? So I did a precautionary stop on the shoulder. Yep, it WAS me!

Another member of the club 3X

I just had my 3rd Carlisle blow-out in a month.

I check my tires regularly as I worked at a service station and am familiar with potential tire problems. In July, one of the tires blew out. It was a sudden and complete blow-out, with tread and sidewall damage. The tire in front of it was not damaged in anyway. I could find no debris, but thought it was possibly the cause. I purchased a replacement Carlisle tire and installed it. This past week, on Aug 7, while traveling on vacation in NY, a 2nd tire blew out. I was very surprised. It was one of the originals as well, and was completely destroyed. This time, the only nearby dealer on a Sat afternoon did not carry Carlisle, so I bought a Westlake tire for the spare. Today, on the return trip to NH, a 3rd tire blew out in the exact same fashion. These tires are not dry rotted, they have plenty of tread, and I check the air regularly-in fact I confirmed them this AM before leaving. Of the 5 Carlisle tires on this camper, 3 have blown-out in less than a month. I've owned campers for over 15 years, and have NEVER had a blow-out. This appears to be a defective lot.

Has anyone had success working with Carlisle on replacements?

Bob

Bob, are these Carlisles the original tires on your Shamrock? I see it's an '04 model, but is the actual build date on the trailer? The reason I mention this, your trailer may have been built in '03. If that is the case, your tires would be 7 years old. A lot of folks go by the 5 year rule when it comes to their tires. Replace them when the tires are 5 years old.

I can only assume they are originals. I bought the trailer in 2008, it had hardly been used. If so, I agree, they could be 7 years old. Still, is it not odd to have 3 of them go in such a short time? I'm thankful they did not go in the middle of the Adirondack trip last year!

I also had a blowout a couple of months ago on my
TT. It was a Goodyear product. The TT is new to me so I don't know the history of the tire. I was not comfortable finishing my trip home without a spare so I searched on my phone for a tire dealer and replaced the spare...took 3 hours before I got back on the road!

I have an 09 Flagstaff 26rbss no blowout yet but am talking w/ dealer about Carlisle st205-14 w/sidewalls cracking after about 450 miles. Just returned from another 400 mile trip and have 2 more doing the same thing! Waiting to hear on the first before deciding what to do.

I just keep my tire pressure checked and use regular air. It's cheaper.
I don't recall my periodic chart very clearly, but isn't oxygen a larger molecule than nitrogen? If something is going to leak it's going to be the skinny cousin.

I also do not understand why adding nitrogen to gasoline (Shell stations) would do diddly squat.
