Why 18-inch G-FX wheels work so well
An 18-inch diameter is the sweet spot for many trucks and crossovers: large enough to clear bigger brakes and fill a wheel well, but small enough to leave room for taller sidewall and a more forgiving ride than 20s or 22s. G-FX leans into that with simple, durable styling and finishes that hide trail grime. If you want to compare proportions, the lineup also runs in 16", 17", and 20", and you can see the whole picture across the full G-FX lineup.

Heavy-duty eight-lug fitment shows up in 8x165.1, 8x170, and 8x180 for trucks like the Ram 2500/3500 and Super Duty. Shop directly by pattern with the 6x135, 6x139.7, 5x127, 8x165.1, and 8x170 pages.
How to choose your 18-inch G-FX wheel
Start with your bolt pattern, since that's the hard limit on what will bolt up. From there, decide on width and offset to match your suspension and the look you're after — aggressive negative or low-offset setups (like a TR-26 at 18x9+0) push the wheel outward for a wider stance, while higher offsets tuck in for daily comfort. Then pick a finish. A simple, no-fuss option like the TM6 18x9+12 Gloss Black Milled reads clean on most builds, while two-tone bronze choices on the TR-18 and TR-26 add contrast. For reference, monoblock truck-ready options elsewhere in the family include the TR-24 6x135/6x139.7 Matte Black, the TR-25 6x135 Matte Black, and the TR-18 5x127 Gloss Black Milled; the TR-12 Gloss Black Milled shows the dual-pattern flexibility you'll also find in 18-inch sizes.
