Just did the 15,000 mile service on my 06 Tacama and noticed something odd.
The front tires are wearing unevenly, but in an unusual way.

The inside edge of each front tire was slightly more worn than the outside
edge. Nothing dramatic, but nonetheless noticeable.

This doesn't seem like either under or over inflation, which would be making
either the middles or outsides wear more, but not just one side. It seems as
though it's a camber problem, which would mean an alignment problem.

I haven't had any accidents and although I go off road a lot I haven't had
any major incidents of any kind. If the alignment's off it seems like it must
have been off right from the start, and it seems odd that it would be so
symmetrically off.

The tires are the stock Goodrich 265/70 Rugged Trail T/A's which I've heard
people on this group describe as crap, but that still wouldn't explain the
uneven wear.

Anyone else experienced this, or have any ideas?

It's underinflation, thanks to Toyota's recommended pressures being WAY too
low. Pump them up to 32. Also, the crappy tires DO wear faster and even more
so with low pressure.

The reason they wear on the inside more than the outside is the normal setup
on the front end. If only one of them was doing it, then it would signal a
problem.

PUMP those tires up!!

There is a recall for ball joints on some Tacoma trucks. I'm not sure if
your truck is affected, but it sounds like you might be having ball joint
troubles.

Toyota recommends 29 front and 32 rear, but I've been running all four tires
at 32 psi since day one, based on the advise of a non-dealer Toyota mechanic.
Come to think of it, maybe OVERinflation is the problem, but I doubt it,
given that it's only on the inside edge of both tires, and the tread in the
middle is just fine.

Thanks for your help.

No ball joint recall for my truck, but I see now that there is a sizable
recall for improper assembly of the tires onto the wheels, which may have
damaged the tire bead. That's a good enough reason to take the truck to the
stealership and have them go over it with a microscope. Thanks a lot.

OVERINFLATION will cause wear in the center section of the tread. Your
report is wear tot he edges, this is the result of underinflation and/or an
alignment problem.

Looks like we are in agreement. Thanks again.

You likely have too much negative camber in front end and maybe a bit
of toe out too. Have front end alignment checkout really good.

In this case, it's also the result of super cheap tires.
