TR31
The G-FX TR31 features eight long, tapered spokes that extend from a recessed center section to the outer edge of the wheel. Its open spoke layout and smooth, deep lip give the TR31 a straightforward truck-wheel design without simulated beadlock hardware or an overly complicated face.
The wheel’s depth changes depending on the width and offset, with lower-offset applications producing a more pronounced lip. A debossed G-FX logo appears on one spoke, while the bolt-on center cap completes the center section. The center-cap design is adapted to the lug configuration, giving the 6-lug and 8-lug versions a consistent appearance despite their different hub sizes.
The TR31 is available in 17x9, 18x9, 20x9, and 20x10 sizes. Fitments cover select 5-lug, 6-lug, and 8-lug truck and SUV applications, allowing the same eight-spoke design to work across light-duty and heavy-duty platforms.
