If lowering the inflation doesn't satisfy you, you might want to try raising
it as long as you are below the max psi labeled on the side of the tire.
Also they are probably MXV4 Plus which is a very good but expensive tire.
If that doesn't help talk to your dealer.
Just purchased a new '06 Avalon. After driving it for about 500 miles =, I
noticed that it is sensitive to lateral tar joints and other imperfection
in the roadway, like moving from teh roadway to a curb apron. It seems it
wants to pull the steering wheel. I'm used to a '99 AUdi quatro which did
not display these kinds behaviors. Can anyone tell me if this is normal for
the steering and suspension geometry on an avalon?
