frequently asked questions

Yes, aftermarket lug nuts with a conical seat will need to be purchased separately. OEM lug nuts will not work.

OEM TPMS will work - the shop that installs your wheels should have an adapter available.

Yes, hybrid wheels can be used as is, without rings. Rings are not mandatory. If you later decide to add rings, you won't need to rebalance your wheels.

Yes, all of our wheels are street legal and DOT approved. The beadlock ring and mounting the wheel/tire as a beadlock is for offroad use only.

Yes, our wheels are hub-centric for most trucks (Tacoma, 4Runner, GX, 2nd Gen Tundra, F150, Colorado, Wrangler and Gladiator). For all other trucks, refer to our FAQ page for recommended hub ring sizes.

Yes, all wheels include ABS center caps. Billet caps are also offered as an upgrade and will work with all wheels.

Opt for the ring that you will use for its intended purpose. The primary function of the beadlock ring is to clamp the tire bead, which will leave a gap between the wheel and ring when not installed as designed.

It depends on setup. Is your truck lifted or stock height? Stock height trucks are best suited for +0 offset. The more negative the offset, the more the wheels will poke out past the fenders.

At this time, we only ship to the contiguous US States, Hawaii and Canada. For shipping inquiries outside of those regions, please reach out to our dealers Custom Offsets and Trail Built.

Had my eye on these wheels for awhile now but hey just didn’t quite tit the aesthetic of my 2nd gen. Had to go out and buy a 4th gen to make them work. lol. Jk, Fit and finish is on point and love that I’m saving prob 10lbs a wheel compared to many other manufacturers. Wrapped them up in 35s and feeling great.

5* All Around

Bought these wheels to replace the TRD Pro BBS wheels on my Tundra. I was concerned because the TRD Pro wheel is a great wheel, but these RRW look great, are lightweight and accept/balance a "good" AT tire with minimal weights. I highly recommend them.

PRODUCT HIGHLIGHTS

AMERICAN MADE

CNC precision machined and anodized in California.

COMPLETELY SEALED UNIBALL

Only our billet UCA has a completely sealed uniball, extending the lifespan of the fastest-wearing component. By keeping the Kevlar-reinforced PTFE liner free from debris and grime, we help ensure it lasts longer.

CAD DESIGNED & FEA ANALYZED

Using 3D scan data, we reverse engineer the geometry and optimize it for lift. This optimized geometry creates balanced comfort and performance both on and off road. Several prototypes are made, fitted, and analyzed to ensure correction of camber, caster, reduce bump steer.

MACHINING DETAILS

Large chamfers at inside radius increases clearance for the coil spring at full suspension droop.
