IIRC, I looked up the SR on M/T web site. talked about rubber compound for wear. speed rating ect. talked about tubed out cars turns/tire scuffing/low wear compound.

yes, it is a street tire not a drag tire. IMHO, it's a med traction tire for the street. Myself I have no NEED for a drag slick or drag radial other than LOOKS, so I do not run one on my truck.

to me they look like a wet-weather tire you see on a INDY500 car. wide with the flame tred pattern.
