I had huge problems with two new sets of Hoosier Vintage TD race tires for=
my TR3. Around $1200 a set, mounted and balanced. I drive my car on the =
street too, so I was able to discover this before getting to the track. Re=
peated tries at balancing went nowhere. I had them "road force balanced" m=
ultiple times in attempt to improve the matter. This machine reads the run=

achine to see how out-of round they were, even at 30. Terrible. They real=

ook terribly between 60-90 mph. Above 90 was better. After the event I c=
alled Hoosier and they sent me another set, no charge. I had to eat the ex=
tra attempts at balancing. The second set was also very bad and a year lat=
er, my second Rolex race weekend was equally disappointing. Hoosier sent a=
third set, no charge. This set was excellent. This event is the only on=

the bad sets be sent back. I have since remounted a couple of lower "road =
force" numbered tires and they are good now. So with some wear, they did g=

Roger Kraus Racing, tire company, recommended truing these tires by shaving=
the tread when newly mounted if they are noticeably out-of round and take =
a lot of weight to balance. =20
Happy motoring,
