[DeTomaso] What a tire blow-out at 186 MPH can do

Tue Jul 23 01:01:05 EDT 2013

Hi gang,

Charlie piped up on the SSCC forum to answer some questions.  With
regard to tires here is what he said:

"Tires. Michelin Pilot Sport PS2s.  Front 275/35ZR18   rear  335/30ZR18
Purchased in Feb '12. Were on their second (last) year of ORR use.
Have been using the PS2s since '07 with no problems."

It should also be noted that Charlie typically runs in the highest speed
classes, where tires are only allowed to be two years old at the most.

For those who were interested in the data acquisition piece, Charlie
says he's using a system by racreye, but their web site's not loading
right now.
