To all of you vocal proponets of the Sumitomo HTRZ-II's, I need your adice =
and opinions.

I mounted my new Sumi's, 245-40-17's on O.Z. Superleggera's, about eleven d=
ays ago.  The initial post-mounting drive was a pleasure.  The tires seemed=
 to "feel" more of the imperfections than the 225/45 SP 9000's previously o=
n the car, but all sounds were more muffled and the bigger ones were felt l=
ess.  Smoother overall was my verdict.  Drove the car maybe five miles on a=
 two lane with somewhat rippled new asphalt and maybe 12 miles on I12's rea=
sonably good asphalt.

The car sat in the garage for  two days.  The temp did not get below maybe =
71F; highs near 90F.  Pull out of the neighborhood and accelerate to about =
45 mph and the car starts to shake itself apart.  Felt like I had square ti=
res.  By the time I'd gone maybe 1.5 miles, things had smoothed out.  I hap=
pened to be making the same basic trip as the first run and I made it again=
 the next day with the same results.  Both times it smoothed out and ran sm=
ooth on the interstate.

After sitting overnight again, I headed out across the bridge into New Orle=
ans with virtually the same result.  Very annoying.  Maybe 60+ miles round =
trip that time, but only the first two or three rough.  Then this past Sund=
ay, after sitting a couple of days, I got virtually the same again as I hea=
ded to the airport for a business trip.  When I returned yesterday after th=
e car had sat for three days in the covered parking structure, same basic t=
emps, as the thermometer read 83F when I got in the car about 7 p.m., I had=
 the worst ride experience of  my life.  The car was shaking twice as badly=
 as before and it took five or six mile to get to tolerable and maybe close=
 to 20 to get smoothed out.  I'm gonig to get in touch with Tire Rack today=
, but I wanted some input from you guys first.  Any remotely similar experi=
ences/redress or anything?   I was really looking forward to getting this s=
etup, but it is really unacceptable as it now stands.

All help and comments will be appreciated.

What is it with this car?!

TIA,

Steve
