When you're upgrading an ATV, UTV, or side-by-side in the powersports tires, brakes, and suspension space, wheel fitment is the first thing to settle. The two RockTrix RT111 sets here look like siblings, but they're built around different hub patterns. Pick the wrong one and nothing lines up.
Quick verdict
Match the wheel to your machine's hub setup before you worry about appearance. If your hubs need a 4x156 bolt pattern with a hub bore no larger than 131 mm, start with the $405.60 RockTrix RT111 set for that pattern. If your hubs need a 4x137 bolt pattern with M10x1.25 studs and a hub bore no larger than 110 mm, go with the $376.29 RT111 set and keep the included lug nuts. The lower list price is $29.31 below the higher one.
At a glance
| RT111 4x156 set | RT111 4x137 set | |
|---|---|---|
| List price | USD 405.60 | USD 376.29 |
| Price bar | ||
| Wheel size | 14x7 | 12x7 |
| Bolt pattern | 4x156 | 4x137 |
| Hub bore | 131 mm | 110 mm |
| Offset | 5+2 | 5+2 |
| Finish | Matte black | Matte black |
Neither set is a universal fitment. The 4x156 set lines up with a hub bore up to 131 mm; the 4x137 set lines up with one up to 110 mm. Match those numbers to your machine before you choose.
Where each set wins
The larger RT111 set wins for buyers on a 4x156 platform who want the bigger rim without changing offset. The smaller RT111 set wins for buyers on a 4x137 platform who want the lower list price and lug nuts included.
Product notes
RockTrix RT111 14x7 Set
The 14-inch RockTrix RT111 is the pick when your ATV or side-by-side runs the 4x156 bolt pattern and a hub bore no larger than 131 mm. That combination covers Polaris-family machines like Sportsman, Ranger, RZR, General, and related 4x156 models. The wheel uses a 5+2 offset and a cone-style conical seat, so it keeps the intended stance and works with standard tapered lug hardware. What makes it worth choosing is the larger rim size for that platform. The limitation is fitment: this wheel is built around 4x156, so it won't line up with a 4x137 hub. Bolt pattern comes first.
RockTrix RT111 12x7 Set
For machines with a 4x137 bolt pattern and a hub bore no larger than 110 mm, the 12-inch RockTrix RT111 makes more sense because it bundles the 10x1.25 lug nuts. That's a real advantage if your Can-Am Commander, Defender, Maverick (non-X3), Outlander, or Renegade uses the 4x137 layout. The wheel keeps the same 5+2 offset and matte black finish, and the conical seat matches the included spline lug nuts. The trade-off is also fitment: it's built for 4x137, so it's not the match for a 4x156 machine. It's also the smaller of the two sets, which matters if you want a taller wheel to fill the wheel opening.
Final choice by use case
Pick the RockTrix RT111 14x7 set for a Polaris-family 4x156 machine with a hub bore up to 131 mm when you want the bigger wheel. Pick the RockTrix RT111 12x7 set for a Can-Am-family 4x137 machine with M10x1.25 studs and a hub bore up to 110 mm when you want the lower list price and lug nuts ready to go.
