That would do it. Especially if you travel it in both directions.
Downhill places much more weight on the front end and will wear the
tires faster. I would probably rotate the tires more often to try to
compensate for the wear. You might want to step up to a stiffer sidewall
and maybe even add some camber to even out the wear on the tires a bit.

Thank you for that advice of
* Downhill twisting causes more front end wear than uphills
* Rotate more often
* Stiffer sidewall might help
* (less positive) camber might help

On the camber, if my search results are correct, the outside edge tire wear
would be due to too much positive camber (top spread out). That seems to
indicate that I would *lessen* the (positive) camber (get it closer to zero
than it is now).

Is that the correct direction?

On the "stiffer sidewalls", I searched for what that means in terms of
beign able to actually choose the stiffer sidewall between two tires was
the aspect ratio and the load range.

Is that correct?

I'm not likely to get a "shorter" tire aspect ratio so the only viable
option left is the higher load range (like going from 102S to 105S).

Are you suggesting that a higher load range tire will have less outside
edge feathering?
Put 70 series LT tires on and run at elevated pressure. You do NOT
want "passenger car" tires on that vehicle. It is a "light truck" and
should have "light truck" or at least SUV tires on it..

Take the word of a retired former Toyota Service Manager, who has also
had experience in Rallye driving. The firstand simplest thing to do is
AIR UP the tires by at least 5 PSI. The next SMART thing to do is get
the alignment verified. When the tires need replacement replace with a
heavier duty tire - an LT rated tire is recommended on that vehicle,
and if it has the 265 65 tires on it, fo to 245 70 instead. Reducing
the width of rubber on the road will reduce the instability of the
tread on hard turns.

It's not a race car - you don't need wide meats on it.
