RT112 8Lug Six Spoke Classic

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.

If you plan to use your OE/factory nuts or lug nuts other than what we recommend above, please check the information below to verify compatibility.
1. Lug nuts must be cone / conical / taper seat.
2. Lug nuts and your lug socket must not be thicker/wider than 1.25", or they will not fit in the lug holes of our wheels.

Verify lug nut compatibility: lug nut diameter must be less than 1.25 in (34 mm), and the lug seat must be cone, conical or taper 60 degree


Rocktrix recommends using car wash soap in the same dilution ratio as you would to wash your vehicle. If it's safe for the body of your vehicle, it's safe for your wheels. Do not use harsh chemicals such as brake cleaner, degreaser, or dish soap.
