Jack,
I searched all the tire sites looking for 165's for my 356SC coupe
and the only ones I FOUND where kelly's and Coopers.I have used both
in the past and won't use either again.(personal opinion) I decided
to upgrade to 185:65's. The tire Rack has 28 different tires in this
size in all speed ratings from touring to performance.check them out
at www.tirerack.com and search by size. Good luck,
Jim
