For all those worried about tires and the new TREAD standards...
From the NHTSA docket:
Several commenters suggested that certain tires produced for specialty uses or antique vehicles be excluded from adhering to the new performance requirements. RMA suggested that the agency exclude temporary spares, various trailer tires, snow and deep lug tires, and bias tires from the applicability of FMVSS No. 139. The TRA asked that special-use tires such as ST, FI, and 8-12 rim diameter and below tires (typically used on smaller, towed trailers) be excluded from FMVSS No. 139 and continue to be covered by FMVSS No. 109. Specialty Tires and CU argued that bias ply tires should continue to regulated under FMVSS No. 109, not FMVSS No. 139 because the agency did not conduct any testing of these tires under the proposed parameters, they may not pass the new tests, and they are not part of the group of tires targeted by the TREAD Act to be upgraded. Hoosier Tires and Denman, makers of small lot specialty tire of both bias and radial design (15,000) per year suggest that limited production tires continue to be covered by FMVSS No. 109 and not become subject to the requirements of FMVSS No. 139.
The agency emphasizes that it is not changing the "on-road" versus "off-road" definition in this rulemaking. It also notes that specialty tire manufacturers are currently required to subject their "on-road" light vehicle tires to the performance tests in FMVSS No. 109 and 119.
The agency is aware of several manufacturers, such as Denman and Hoosier, which produce bias tires for racing, off-road, and antique/classic car applications. These tires represent a very small (less than 1 percent) segment of the market for light vehicle tires and are not offered by any vehicle manufacturer on any new light vehicle sold in the U.S. Further, the number of miles that they are driven per year on highways is insignificant. Therefore, the agency has decided to exclude bias, ST, FI, and 8-12 rim diameter tires from FMVSS No. 139. These tires, however, will continue to be covered by FMVSS No. 109 and 119. FMVSS No. 109 will not be deleted.<ul><li><a href="http://www.nhtsa.dot.gov/cars/rules/rulings/UpgradeTire/Final/Index.html#ref98">One VERY long document</a></li></ul>

Re: For all those worried about tires and the new TREAD standards...
This link will take you to ImprovedTouring.Com
It has an small discussion on the Hoosier Road Racing tires and their future direction...
Also on that page you will find a link to "press releases" that Hoosier Tire put out when the debate started (or when the laws were proposed) and also a link to their public view now.
Looks like we will actually end up with possibly a "better" hoosier racing tire!!!
