Wheel Description
Our RT112 features a simple yet effective 6 spoke design to give you the modern look. These wheels are strong on the trails and easy to clean. Popular fitments include Chevy Silverado; GMC Sierra; Dodge Ram; Ford F250 F350. Refer to the fitment guide below to verify fitment.
With no wheel spacers or hub adapters required, the -12 offset provides roughly 1.5" more inner clearance than your factory rims to allow for bigger or wider tires. Fits everything from the factory 17" tires all the way up to 33, 35, 37 and beyond (Note: Lift kit required for oversized tires). Your rig will look as good as it performs!
Compatible with majority of OEM TPMS sensors, however new TPMS valve stems may be needed. NOTE: Not compatible with OE TPMS sensors on steel wheels.
NOTE: May not work with OE/Factory Lug Nuts (dependent on vehicle year/make/model). See lug nut compatibility section below or message us with your vehicle information for assistance.
