Trailer Tire wear

On May 1st I purchased a new 2011 travel trailer. I have taken three trips for a total of approximately 600 miles. I noticed last week that all four tires are showing abnormal wear on the inner and outer edges. The trailer came with ST205/75R14C tires. The MFG. date is 26-10. I inflate them to 50 PSI which is the recommended pressure on the sidewalls.

I did some more research and found the tires on my trailer have a weight capacity of 3520 lbs per axle, but the axles are rated at 3600 lbs. Should the tires have an equal or greater carrying capacity? The tires are brand name H188ST.

Hi JCher,

The tire placard on your camper states the axle rating. What does the axle rating say the limit is?

The TT manufacture is supposed to equip the TT with tires, springs and axles to meet the stated GAWR. (Gross axle weight rating) It is often times that the axles themselves are stronger. The springs may be as well. The tires may be the limiting factor. The weakest part in the suspension should reflect in the GAWR.

Now to your tire wear. If you weighed both TT axles on a scale along with WD engaged on the truck, the camper loaded as you go camping and that weight is below the GAWR as stated on the tire placard of the trailer, then something points to a suspension problem. What was the weight slip stating the weight was and what is your GAWR on the TT?

The turns a tandem axle trailer makes does add some wear to the other edges of a tire. However I have not yet seen is come on the inside from just turning.

To help better we need to see what the tires look like. Any chance of posting some pic's of the tire wear? Try to get pics straight on and in good light. Take pic's of all 4 tires and label them which position they came off of.

Yes, overweight can case the outsides to wear however there may be other suspension issues not right. TT's not being in correct alignment is more common then one thinks.

The axles can be made wrong, the hangers welded on wrong, they can even assemble them wrong. In my case I was the lucky one to get a frame with the hangers welded on wrong and the axles made wrong. I must say I did learn a bunch from this experience. I installed 2 new axles, corrected the hangers and aligned the system in my yard. It still shocks me if I can do this how this happen with all the modern methods of manufacturing we have today.

What make and model camper is this?

Hope this helps
