The Rocktrix RT115BL is the beadlock version of our popular RT115 wheels. The aerofin feature of the wheels paired with forged beadlock rings create a unique and head-turning combination. Made of forged T6-6061 aluminum, the beadlock rings allows you to conquer your favorite trail at much lower tire pressure without the risk of tires de-beading. With no wheel spacers or hub adapters required, the -12 offset is approximately 2" more aggressive than your factory rims, while the -38 offset gives almost 3" more clearance for bigger, wider tires over factory wheels. Designed for both on-road and off-road driving. For daily driving, mount tires onto the traditional bead seats. For off-road driving, secure tires using the beadlock rings. Popular fitments include Jeep Wrangler, Gladiator, Grand Cherokee; Toyota Tacoma, 4Runner; Ford F150, F-150 Raptor. Refer to the fitment guide below to verify fitment. Compatible with majority of OEM TPMS sensors, and OEM TPMS valve stems. Note: OEM Factory lug nuts may not be compatible. See lug nut compatibility section below, or contact us with your wheel information for assistance. Warning: Tires secured using beadlock rings are for off-road use only may not be legal for highway use.
