Why just one tire wearing more than the others?? - Page 2

**JFlightRisk** · 08-05-2019, 08:05 AM

I found my father's old toe-in gauge in my garage, so when the TT gets pulled out straight next week, I'm going to see if I can check the axles. Right now, it's beside the house, and when I put a straight edge across the wheels, it touches only the fronts of the tires, so they're tweaked from jacking it in its spot. I'll update when I get to measure them. Just not sure if they're suppose to track perfectly straight or toe in a little.

Here is a source of information on trailer alignment and tire wear. . . .

I had a similar wear issue caused by being out of alignment. Once the alignment was corrected, no more uneven tread wear.

Good info. If anything it probably is the "bent axle" syndrome, since it's just the one tire. I'll be able to check it more accurately when it's in the driveway, away from the house. I do have things to use as a straight edge on them. If it turns out that way, I think I'll put in a call to Thruway Spring in the city, and see what they can do for it.

Yeah thanks SloPoke. Very interesting read.

I'll have to check my alignment pretty soon - before I put new tires on as I've got one tire wearing differently as well.

This happened to bro in law. Axle was bent.

My experiences with towing our dual axle sailboat trailer across country many times:
Abnormal:
1: Bent axle
2: Badly welded brake backing plate
3: Bent frame
4: Axle alignment
4.5: Axle weak from overloads (this one is debatable!)

Considered normal

meaning user correctable)

5: Heavy load not properly distributed
6: Load on right side due to road camber. Heavier.
7: Tire inflation
8: Tire balance
9: Lug nuts not torqued properly or evenly. Rim not seated.

The above are the major points I learned when diagnosing an axle vibration issue.

Maybe #1,2,4, or 8. We'll be doing the yearly week long family camping/get together thing this coming weekend, and it's very close by. I think I'm going to call Thruway Spring after we get back home, and talk to them about the possibility of aligning the axles, or straightening out the wheels a touch.

I don't believe it's #3,4.5,5,6, or 9. I do retorque the wheels myself, and am careful to hand-snug the lug nuts before a three sequence torque.

Thanks for the laundry list of possibilities.

An update to the lest rear tire wearing more than the others.

Today, I put a straightedge against the sides of the tires on both sides.
Curbside: Straightedge is touching the rearward sidewall on both axles, with spaces on the front sidewall.

Roadside: Just the opposite. Straightedge is touching the front sidewall on both axle, with aa space on the rear sidewalls.

I need to do a bunch more measuring from frame points, but it appears now the spring saddles that are welded to the frame are not equidistant from the front of the trailer.

Of course, the spring saddles can't be slid due to the centering bolts through the spring pack. It does not look like an easy alignment issue.

The TT isn't "eating tires", and (here's where all of you can beat me up) it's got a fair amount of miles on it, and the tires are the original ones that came on it. (go ahead, get it over with!!) It's a 2012.

Yikes! That's unfortunate, JFlightRisk! I haven't tried this alignment measurement myself yet; I'm afraid of what I may find (as in "more stuff to obsess over")! However, I did measure from the back of my springs to the end of my frame rails a few weeks back, and they seemed to be equidistant.

I wonder: have you ever had anyone drive behind you when you are towing your TT, and see if the "thrust angle" looks off? In other words, does the rear end of the TT noticeably not track inline with the front of the TT?

Based on your description, it would seem that the rear end of the TT would have to track slightly to the left of the front.

Best wishes,

Sorry for the late reply, but we're at a campground with iffy internet.
I haven't had anybody ride behind us, but looking in the mirrors down the sides of the TT, it looks like it's tracking normally. I will do the frame measurement when we get home.
