Importer/wholesale distributor Omni United USA is expanding the scope of its Timberland SUV/light truck tire brand by adding an all-terrain light truck version of the brand that it's cross-promoting with outdoor shoe brand Timberland L.L.C., along with increasing the size range of the Timberland Cross SUV line. Omni United also is upgrading its Radar Renegade M/T light truck line, incorporating design features gleaned from experience in off-road racing into the new R7 line, which Omni said is targeted at the serious off-road enthusiast.
