tires on a 100cs need advice

[ASTHAMMER at aol.com]

Hello all and merry christmas,

One quick question... I recently purchased larger tires for my 100CS.  I went
up to 205/55/15 V rated.

My car no longer handles the way it use to.  It feels like gusts of wind are
crossing in front of me on the highway.  my car now tends to follow the
grooves in the road and it just makes me sick.  Could it be the bigger  tires
or is it just coincidental that it started doing this just after putting the
new tires on???  Could this be a suspension part wearing out instead.??

thank you in advance for your help.

sincerely

ted
