outside tires wearing

[rparlaman]

I own a 2000 30ft, sandpiper fifth wheel and the tires are gone with maybe 3000 miles. I`ve talk to different places and said thats the nature of trailer tires because when you pull it around corners it drags the tires. All of mile trilers did it, wore the outside edge and starts cupping. I`ve have talked to rv shops and they told me there is no alighment on trailers. Everthing is done at the factory and set there. So i called Elhart Indiania and they told me they do it all the time up there. Know one on the east coast can do it Need help in Maryland, at the time i put all new goodyear marathons on. The old ones were Carlies.

It is true that trailer suspension has no adjustments for alignment but trailer suspension can be aligned. It is accomplished by bending the axles.



Almost any good heavy or medium truck service shop can perform an alignment for you. It is accomplished in the same way the front suspension of big trucks is aligned. I've had several trailers aligned including Airstreams and Avions. The typical price I've seen is approximately $100 per axle.

I have traveled several years and never had a problem like you describe on my 34' fiver. It weighs 15,000 lbs and the tires do scrub when you make sharp turns, but not enough to wear them out in 3000 miles. Something isn't kosher with your suspension or the amount of air you are carrying in the tires. I keep mine at the pressure written on the tire sidewall which on mine is 80 psi.

Unless you have driven 3000 miles doing figure 8's in a parking lot, there's no way this is normal. I have probably 12,000 miles on our current 13,500 lb 5th wheel, and the Goodyear Wrangler HT's (yeah, I know ) still look like new.



I'd be for finding me a competent truck or trailer repair facility with alignment capabilities (and, yes, trailer suspension can be and is routinely realigned) and get to the bottom of this problem.

Were the axles ever "flipped" to change clearances? My small car trailer has a built in camber ( top of tire is in ) of 1 or 2 degrees. If the axles have that built in camber and the perches were welded on backwards initially or they were "flipped" improperly could cause this. (disclaimer IMHO )I think that the "top" has to stay on "top" or re camber the axle/ reweld new perches to keep it on top. Sounds silly being that without the backing plate on both ways would look identical. Find a trailer place that knows thier business. They have to be out there.

Look at axle ,the axle should be high in the center if you have a spring set up ,If axle was (so called flipped) bend should still be up . All four or more wheels should be aligned square to the frame when rolled to a stop on flat ground like a large parking lot , marking the center of each wheel and marking the location of the four corners of the frame front and rear of the mounting location on the frame will when measure for squareness tell you some useful information . You have a serious problem and should get it taken care of before bad accident happens. Hope you find a answer to this soon. LOL Ron Bissett in Metro Louisville KY
