I have the above NEW problem on one of the four tires on my trailer, and hope someone here can help. I'm completely confused, since in 30 years I've never seen anything like this before, and before I start a lengthy & time consuming process trying to islolate the problem, I thought I'd try here. Here's the situation, and for reference, there is a picture of this trailer in Jim's trailer reference section. Also in page 2 of Cetecea there is a picture of me standing in front of this side of the trailer.It is a tandem axle 6000lb capacity trailer (for my 25 outrage), with conventional springs (just replaced last year) and ST205 x 75 R14 (load range C) Goodyear Marathon Radial tires (balanced). I just towed the boat 1400 miles, and during that distance the left front trailer tire went from being almost new to completely worn down, on the OUTSIDE edge, and for only HALF of the circumference of the tire. The tire has to be replaced. The other half of the outside edge is not worn at all! The other 3 tires on the trailer show no unusual wear at all. I have just spent some money on this trailer, and it is in excellent condition. Here is what I had done before the trip, and one of these new changes must be causing the problem:
1. I had new, original manufacturer supplied, and dealer installed, 3500lb galvanized axles put on the trailer. This was simply done for preventitive maintenance after 11 years and 80,000 miles of use.
2. I had new Stainless Steel disc brakes installed on all four wheels, and they came complete with a one piece new hub & rotor combination.(brand is Tie Down Engineering, Inc.) These were also supplied by the trailer manufacturer and installed by their Dealer. Everything appeared to be a very nice job, although it appears that this same wheel is leaning in ever so slightly at the bottom. Without the boat on the trailer at the time the work was done, I didn't think much about this, figuring the weight of the boat would compensate for this extremely slight, barely noticeable, inward camber at the bottom.
3. Before leaving, I noticed a small leak in this same tire, resulting from a nail, and took it to a Goodyear Dealer who dismounted it and fixed the leak. When he re-mounted it on the galvanized spoke rim, it was not re-balanced, nor were the original weights removed. This seemed relatively incompetent to me, and I complained, but they insisted that it wasn't necessary to balance any trailer tire, (which is not true) and that the tire was remounted in the same position on the rim. So I let it go.
So my question is:
1. Is it possible that I got a defective, untrue axle? The only thing here is that if the axle is causing the tire to not hit the road squarely, I would think that the edge wear would be uniform all around, and it's not.
2. Could a defective hub, or bearing job, cause this kind of abnormal tire wear on only half of the tire?
3. Could the problem be an out of balance wheel, or even could they have damaged the rim re-installing the tire. (The wheel exibits no wobble when turning on the axle)
So I'm confused. If anybody can help, I'd be most appreciative. I'm going to start by getting the wheel off the trailer and checking it out for problems. My best guess is that I got a defective axle installed, which is what I don't want to hear! What a headache.
