Default Are RE070's legal in AutoX?

As per the discussion from last night about RE070's being non-legal street tires, I went to look at the rules.

Since our "Street Tire" class uses the "Street Touring" rules for tires, here is what I found.

Quote:
14.3 Tires
Tires must meet the eligibility requirements of the Stock category (excluding
13.3.F), with the following additional restrictions:

A. Tires may have widths up to and including 225.

B. Tires must have a minimum tread wear rating of 140.

C. Tire models must not appear on the following list, which may be altered at any time by the SEB upon notification of the membership.

Pirelli P Zero Corsa
and from the Stock rules
Quote:
13.3 TIRES
Any tire which is OE on a car eligible for Stock Category may be used.
Non-OE tires must meet the following requirements to be eligible for
use in Stock category:

A. The tire must not appear on the following list, which may be altered at any time by the SEB upon notification of membership.

No tire models are currently listed.

B. No tire models will be approved for competition during the rest of the year after April 30 of each calendar year. Each eligible tire model must meet all requirements of Section 13.3 by April 30, and must continue to meet them thereafter. A tire model will normally be determined by the designation in the Tire Guide. However, any of the following changes or similar changes (as determined by the SEB) will also be considered to represent a new model for eligibility purposes, even if the designation does not change: change of tread pattern at either full or partial tread depth; characterization by the manufacturer or distributor of a tire as “new” after April 30. A tire model which was previously allowed by these rules continues to be legal until specifically disallowed. This follows years of precedence on eligibility for discontinued tire models. If a manufacturer reintroduces a tire model which was previously discontinued, that tire will be considered a new model. Therefore, it will have to meet the rules specified in SR Section including the April 30 introduction date.

C. The model of tire must be listed in a current or previous two years of the Tire Guide and Tread Design Guide, or otherwise be approved by the SEB. The tire model must have Department of Transportation approval.

D. Within each tire model, the sizes which are available must be equally available to all competitors. Tire model variations differing from standard specification, delivered only on a limited basis, or only to selected competitors, may not be used.

E. No racing tire or recap (on any casing) may be used.

F. Each tire model must be sold in at least four rim diameters, with a total of at least six sizes.

G. Tire must fit the allowable wheels and fender wells without modification.

H. Each tire must have non-zero measurable tread depth (i.e., points where it is possible to obtain positive measurement values) as described in Section 3.3.D. Tires may not have cord visible at any time during competition.
So, the rule that was brought up at the meet (that the tire must be sold in 4 diameters with 6 sizes) is actually not applicable to the ST rules. I think we are safe to run RE070's in a Street Tire class.
