[DeTomaso] Hoosiers-long & Tech at Silver State today

[Mad Dog Antenucci]

Jack-All ORR participants,
   
  First let me say Larry has only run Silver State once in the last two years. Today and even last year Larry probably would have difficulty passing tech with Hoosier's unless they were R3's....
   
  Tire Tech have strong reservations on Hoosier R4's and R5's based on data collected from tire blowouts of Hoosier's...and even Jason had difficulty at Tire Tech this morning with Hoosier R6's based on two factors, one being he had run the tires at the Pahrumph track event last month and two they have no data on R-6's and had nothing but bad data on R4's and R-5's.. 
   
  They lowered Jason's proposed 140 down to 110...the good news is he is running in 125 group. Eliot and I had no trouble passing tech but neither of us are running race or DOT race tires.....at this point for any open road racing unless you have Eagles with "inner-liners" stick with a good hi-performance street tires that have either W, Z or Y (186 mph) speeding.
   
  fwiw

  IMHO, the main drawback of Hoosier DOT tires is, their rubber compounds 
provide monstrous traction- and that translates into very rapid tread wear. A pair 
on 10" rear wheels Judy and I ran for a time did as follows: 
450-horse Pantera was driven sedately to autocrosses about 30 miles away 
where the owner, myself and wife Judy ran it 3-4 laps each on what was usually a 
60-75 second paved course, then the car was sedately driven home & parked until 
the next event. Tires were rotated now and then. After 985 recorded miles by 
the 3 drivers, a thin white streak of fabric was showing most of the way 
around both rear tires! We barely completed the season without having to buy a new 
pair. In the hotbed of prepared-stock autocross that was N. California in the 
'80s, both ends of that poor Pantera were sliding all the time we were on 
course! Note that I won two Regional championships, the owner won one and Judy won 
4 (Womans Class), before we began getting paint cracks near the decklid & 
windshield posts, and the car was retired from competition before the underlying 
metal began separating.

More recently, Larry Stock of the Pantera Parts Connection currently runs 
Hoosier DOTs on his do-everything red Pantera, and swears by them for SS running 
above 150 mph (sometimes well above), low-speed autocrosses with the Nevada 
SCCA and the occasional drive to work in semi-heavy traffic. His Pantera was the 
fastest P-car at the '07 'Vegas Fun Rally- on Hoosiers. He also sells 
Hoosiers. 
Bottom line: if you can afford the rapid wear rate and have a chassis brace 
system to forestall body cracks, they will likely work great for cars that are 
actually driven hard. Just don't expect long life as well unless you drive 
sedately & only want them as rim-protectors. To discuss all this with a real 
user, browse to for some right-now, real-life 
experience with Hoosiers.
FWIW- J DeRyke
