Drives roughly bounces like its back shocks. Not smooth at all feels like the tires are bad..Only in the front. Bought new tires. Feels like I went over a bump but its smooth pavement

If you never had the problem from 2006 until the new
tires went on you have both a financial issue,as well
as some tough diagnostic work to do.

I don't have all the answers for you but the tires
are the focus of the starting point.

I would rotate one tire at a time from the
front to the back
Mark the inside of your wheels with a sharpy,
1 & 2 on front 3 & 4 on the rear
Make a chart on paper of the positions your
tires are at. You should have that for all your
vehicles.

You may have a bad tire that is so heavy on one
side it won't balance out.

I have a Lincoln LS that I run 42# in front and 38#
in rear and it is not at all hard or bouncing
