MMT was an off-road tire manufacturer in 1992 during the events of Grand Theft Auto: San Andreas. It supplies tires for the San Andreas rendition of the Sandking and the BF Injection both of which are off-road vehicles. Their logo can be found on the sidewall of their tires. They possibly supply other vehicles that participate in the Sand Masters Cup. MMT tires are not fitted on any other renditions of the vehicles.
