RE: Fix for wander after +1 wheels/tires?

["Glen Powell" <gpowell@acacianet.com>]

Does anyone have any ideas for fixing  excessive wandering, such as on a freeway
with even shallow ruts, my 4KQ wanders/veers badly.  Can't even prevent with
steering inputs.  A few facts:

--  I put on +1 wheels (15"x7" Borbet TypeH wheels instead of 14"x6" stock) and
1" wider tires, i.e.  Dunlop D60A2  205/50-15's  instead of 205/60-14's.

That's the prollum right there! Wider tahrs & wheels and/or wheels with the wrong offset. 
Very common problem/mistake. Bet the wheels manufacturers never talk about this.....

--  Had the alignment re-checked 3 weeks later.  The alignment shop says the
geometry change due to the +1 wheels/tires is  too much and there's nothing to
be done.  

Sounds like the correct diagnosis, unfortunately.

I don't understand how this can be the explanation since the tire
circumference is same as stock, and the Borbet TypeH offset is same as stock I
think.  

Confirm this wheel offset assumption.

I have an AeroStar with +1 wheels and even wider D60A2  tires and it
still tracks like a champ on the same freeway ruts.

Very different suspension designs.

Maybe there's a non-standard alignment spec fix?

Maybe, I doubt it. You may have to learn to live with it or change back or get wheels with correct
offset.
