In CRA the teams are aware that you can run the F-55 tire when track conditions require it,I know we carry a couple of them in the trailer all the time( just in case). But I also know that our Hoosier dealer doesn't carry very many of those tires due to the fact that very rarely do we face such bad track conditions.
I don't know if it really made a difference that Darren had a 55 on his car,since earlier this year when he drove the car I work on at Vegas with similar track conditions and we ran a 2 compound and it went the entire 30 laps,while other teams ran a 55 and had no more tire left than we had.Darren in my opinion is very good at working the throttle and keeping the car hooked up and not abusing his tires.:clauson:
