Non-DOT Tires

[John Graber]

I wan to run some Non-DOT tires. Either buying cheap take-offs or buying new for tire longevity. Non-DOT tires are penalized in the TT system, yet their benefits clearly help a racer and do not help a TTer from my perspective.

 

Who's with me here?

If they help a racer, why wouldnt they help a TT guy?

We addressed this issue in GTS. Everyone seemed to agree that the non-dot tires (Grand Am, etc) were no grippier than R6's. The ruling was that this opens it up to having to determine (usually on an ad hoc basis) points on every tire out there.

 

I'm going to use them for practice and swap for qual/races.

You're nuts if you don't think some stupid soft compound Goodyear non-DOT true slick would be faster for 1 lap than a Hoosier A even. The Grand Am and similar Hoosiers (like what Koni Challenge runs) are +10 and classed fairly as well.

 

other than the R888s at +7 (should be +5, despite the marketing they are NOT faster than the RA1) the tires are right.

what amazes me is how fast the world challenge gt cars on the r888's (i believe).

All the TTS/U/R guys in my region swap back and forth between Hoosiers and Goodyear or Michelin slicks.. there is a considerable difference between Hoosiers and the non-DOT tires. Typically the slicks are a full second faster on a 1.5 mile track, if not more. I don't know if that justifies 20 more points, but it's debatable.
