Tire Failures/Axles Question

A friend and I both have a 2011 31TS wildcat and we have both had tire failures at about the same time frame. Tires were properly maintained and periodically checked for cracks, etc and had about the same mileage on each. A neighbor has had similar experience and suggested that the axles might be too light for the trailer and contents. Where can I locate information that will tell me what weight the axles that are used on this model are rated to carry? We are both newby's at this and could really use the information

There is usually a tag on both axles about in the middle of the axle that will tell the axle rating.

Just a thought...

How could under rated axles have caused tire failures?

Now if the axles failed, I could see it.

Tire failures are almost always road hazards (potholes, road trash, or curb strikes while turning), overloaded camper for tire load rating, improper inflation for actual load, excessive speed for load on the tire (ST Tires are load rated at 65 MPH max), or an actual internal defect (rare). Pretty much in that order...

Your tire and axle load info is on the "Placard" or certification label that is affixed to the left (driver side) corner of the RV



You should also have this information in your owners literature.
Inflation should be set each travel day while the tire is cold (not run for an hour and not in the sun)

You might want to read my blog to learn more about tires.

I was just checking my unit today for various things, tires and axles seem to be the main cause for concern among most RVers and I'm no different. I'm a real stickler for reading manuals and decals, but on my Flagstaff 5er, the original tires were load range C and as per the stamp on the tire, maximum inflation is 50 PSI. On the decal on the side of the trailer, it says ST 225 R15 C Max pressure 65 psi.. good thing I don't believe Forest River. On the inside of the cupboard it says the right tire pressure, if I was a novice and filled the tire to the decal specs, I'd be way over inflated. A sure lawsuit if this caused a blowout due to over inflation.

If you have two different Cert. Labels and they give different info then one is wrong and must by law be replaced by the dealer/manufacturer.

You van file a complaint with NHTSA. They can order Forest River to provide new correct labels. Go HERE and select File Tire complaint.

Note you will need the TT VIN and tire DOT number.

If you can capture in-focus pictures of the two different labels that would be good. In your complaint advise that you have pictures of both labels.

You might try and contact other owners of identical model RV to see what they have.

PM me if you need additional info or help with this.

RE tires failing due to being 15 psi over inflation. Very unlikely. While just about anything is "possible" under the right circumstances, In my experience new tires (no damage or abuse) are good for 3 to 4 times the inflation on the tire unless the tire is not mounted correctly. Then it is possible to fail at close to the pressure on the tire. But once a tire is properly seated you should never see such a problem.

Thanks for your reply, I will attempt to attach a couple pictures I took, one on the side of the trailer, and the other in the cupboard. I removed the trailer serial number, since I'm cautious about such things. You will notice on the side decal that the tires are C rated yet say they can be inflated to 65 psi (?), yet on the inside cupboard they are rated for 50. Also, on the outside decal it says my bolt pattern is 6, yet it is 5. It appears somebody put the wrong label on, it always makes me wonder what else is wrong with these units with a glaring mistake like this, neither FR or the dealer picked up on it, so much for quality control and dealer prep.

Thanks for the info.
1. Since you are in Canada I need to get a contact at Transport Canada for you to contact as I don't think NHTSA (US-DOT) will consider this actionable since the RV was sold in Canada.
2. I suggest you submit something in writing to Forest River giving them the VIN, Exact tire size & Inflation information from the two different forms.
3. Lets start a new thread here with the exact model RV you have and see if you are just an exception or if there are other units out there with the incorrect info.
4. You might ask your friend with the 2011 31TS wildcat what his placard and label say and let me know.

I am more than willing to start the thread but starting of with "We have identified two units..." or "We have two identical units with different safety information...." will make a difference.

I am at campground so do not have access to my ref material. I will do some research tomorrow.

One other question. What is the actual size, brand, load range, max load in Lbs & Kg and psi molded on the tires?

Roger
