jeffm5150 Posted February 9, 2013 Share Posted February 9, 2013 I've got non-DOT-approved Hoosier 165/70-10 tires (for a classic Mini) that I'm trying to figure out the correct TT points deduction. They don't seem to fall into any of the seven categories listed in the classing form but it seems reasonable that there would be a deduction for these tires. a) they are non-DOT-approved b) they are not racing slicks (I assume since they have a tread pattern) c) according to Hoosier these tires don't have an official UTQG treadwear rating, but they said unofficially it is around 80-120. So, can I even run these tires in NASA TT? And if so, which points deduction is appropriate (if any)? For reference here's information on the tire: http://www.hoosiertire.com/pdfs/pb44391.pdf Thanks for any insight into this question. Quote Link to comment Share on other sites More sharing options...
TurboShortBus Posted February 11, 2013 Share Posted February 11, 2013 1) The following DOT-approved R-compound tires: BFG R1S, Hoosier Wet DOT (if used in dry conditions—seesection 6.7) + 15 2 ) The following DOT-approved R-compound tires: BFG R1, Goodyear Eagle RS AC (auto-cross), Hankook Z214 (C90 & C91 compounds only), Hoosier A6 +13 3 ) The following DOT-approved R-compound tires and those with a UTQG treadwear rating of 40 or less not otherwise listed in these rules: Maxxis RC-1 (examples: Goodyear Eagle RS, Hankook Z214 (C71, C70, C51, C50), Hoosier R6, Kumho V710, etc.)(note: GACTSCC tires OK) +10 4 ) The following DOT-approved R-compound tires: Toyo Proxes RR, Hankook TD +9 Cup, Nitto NT01, Pirelli PZero Corsa, Toyo R888, Toyo RA-1, Yokahama A048, etc) +7 5 ) DOT-approved R-compound tires with a UTQG treadwear rating of 50 to 130 (ex. Kumho V700, Michelin Pilot Sport Cup, Nitto NT01, Pirelli PZero Corsa, Toyo R888, Toyo RA-1, Yokahama A048, etc) +7 6 ) DOT-approved (non-R-compound) tires with a UTQG treadwear rating of 120-200 (examples: Toyo R1R, Dunlop Direzza Sport Z1 Star Spec, Bridgestone Potenza RE070, Kumho Ecsta XS, Yokohama Advan A046 & Neova AD08, Hankook R-S3) +2 7) Non-DOT-approved racing slicks +30 (of any origin—re-caps and re-treads are not permitted) Based on the fact that they are non-DOT, do not have a treadwear rating, and there is no specific exception for them (as with the CTSCC Continental/Hoosier tires), I would assess +30 per A7. b) they are not racing slicks (I assume since they have a tread pattern) As an extreme example, a set of intermediate Pirellis from Vettel's car would have a tread pattern and be non-DOT for +30. This likely falls under the "if it's not worth the points, then don't use it" category, although it's probably impossible to find a DOT R-comp tire for a 10" wheel. Can you put some blingy 13s on it, or would you have to jack it up like a donk? Mark Quote Link to comment Share on other sites More sharing options...

Mark As far as I can determine the _only_ DOT-approved 165-70/10 tire is the Yoko A008 road tire which I use as a road tire (hard as a brick). There are only about 3 decent softer compound tires but they are all non-DOT-approved. If +30 is the only result then my situation is pretty clear. No, running anything larger than 10" is not really an option. I will be contacting Hoosier today to attempt to get a treadwear rating or rating range in writing for the HO T.D.S.

It would be better to directly contact the National TT Director (Greg Greenbaum) with your situation before asking Hoosier for information that may or may not be acceptable to the National TT Director.

Mark Too late. Hoosier is e-mailing me about this already BTW, I remember when someone (who shall remain nameless) attempted to educate us on these forums because we didn't know that ANY car can use a 255/35-18. Yes, I did go there. Quote Link to comment Share on other sites More sharing options...
Varkwso Posted February 12, 2013 Share Posted February 12, 2013 Sure you want to go there? Pretty sure I saw 18s on about everything driving through Atlanta on I 20. Quote Link to comment Share on other sites More sharing options...
National Staff Greg G. Posted February 14, 2013 National Staff Share Posted February 14, 2013 Jeff M, Unless you send an e-mail request, the tire will remain at +30 points. Quote Link to comment Share on other sites More sharing options...
