From the 2010 SCCA Solo Rule book

J. Tires legal in Stock, Street Touring, or Street Prepared are permitted

Stock tire rules

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 Section 13.3 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
(DOT) 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. Siping or regrooving
of tires is not permitted.
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 3.3.3.B. Tires may not have cord visible at any
time during competition.

I'm going to bet it will be the same as last year, any DOT legal tire is ok for SM.

[snoxracer183]

I believe these rules are the final draft for this year.
