01 accord lx pulls a bit on some expressways

Hello,
I own an accord lx 01 and have noticed
that here in the atlanta burbs driving on
I-985 north of atlanta, I notice the car
move a bit side to side when it's driven
over 60 mph.

Now, I don't notice any pull when driving
on I-85 North of atlanta. It may be the
roads also.

Is there a way to determine if it's an alignment
problem or not? Or an inflation issue with
the tires. All 4 tires are about a year and
half old so fairly new.

Thanks!

 

Sorry, if this is a dumb question, but I have experienced this sort of thing
before. Do you notice very small grooves cut into the road? They will be
with the flow of traffic. This will cause this. Same sort of thing when
you go over a country-road bridge that is grating. The car just seems to
get a little loose. Also do you know anyone else who drives on that road
(or you in another vehicle) that can confirm the road unevenness. There are
stretches of roads around here that make my vehicle go side to side,
especially if the road is warped from heavy traffic.

If it was anything besides the road, it would happen all the time.
