The ornamental design for a surfacepattern for a tire sidewall, as shown and described.
FIG. 1 is a perspective view of a surface pattern for a tire sidewall,
showing my novel design; and,
FIG. 2 is a side elevational view of a surface pattern for a tire sidewall,
showing my novel design.
The zig-zag features in the figures are lined to indicate the color gold,
and the thin, narrow band on each side of the solid black band is
understood to be white.
The broken line showings of a tire and lettering are for illustrative
purposes only and form no part of the claimed design.
