[Fot] Race tires

[tr4racing at googlemail.com]

Hi,

 

I run A7 on the IMSA TR8. They seem to last well. I run down the tire first, before the compound shows any change.

Next year I will try the Speedster on my TR4 for the first time. Curious how they will perform.

 

Cheers

Chris

Tony,

 

I do not have as much experience as the rest of the group on vintage tires.  In March at the VDCA VIR Wild Hare, I ran a new set of Hoosier HOTDRs (24x7-15) for 1 qualifying, 4 races (I flat spotted one set in the first qualifying when I locked up).  My best session was the last race on Sunday with this set.  In April, I ran the same set for 4 more sessions at VIR again, running the tread down below spec.  I understand the HOTDRs are actually the same compound as R7s.   I have not run RRRs, but understand they are a little harder compound, and might last longer.

 

Sorry I missed everyone at Lime Rock – wish I could have been there, but was fun watching on youtube.

 

For what it is worth.

Are the Proxy RRR the go to tire ?

This past weekend at Lime Rock , I ran new Hoosier speedsters . After 5 heat cycles, they were absolutely rooted . Yeah, I ran them hard … but still :-/
