Larry, et. al.,
Well kudos to Larry to be the first to suggest the tire - and thank you to
all of you who had lots of great suggestions.
I jacked up the right rear (that's where it felt like the shimmy was coming
from) and sure enough the tire was warped... I guess the belts inside had
delaminated from the tread.
I guess that's what I get for having 15 year old Riken tires on the car.
It may be interesting to note that I usually request that when people detail
my car that they don't put the oily tire shine on. This last time I forgot,
and I found my tires bathed in this oily gooey tire shine mess. It was only
a week after that that the tire started the wobble. I have to wonder if the
two problems were connected, although there's no excuse for me driving on 15
year old tires.
Well, I put my spare on. You will laugh when I tell you my spare is a brand
new 25 year old Michelin XZX 165 15 tire. The thing has never been used and
still has the injection molding excess bits on the tread. Oh well, at least
the car is driveable until I can get 4 new 185 70 R 15 tires here in HK.
Those are "special order". Have to wonder how long it will take to get!
Cheers,
Alan
