About This Wheel
Pick up the M45 Portal and the first thing you notice is how deliberate the face is — deep-set spokes with machined faces that catch light differently depending on the angle, backed by a gloss black base that adds depth without going flat. It's not trying to mimic a truck wheel; it's designed specifically around UTV proportions, so the 7-inch width and 18-inch diameter actually look balanced on a Polaris or Can-Am rather than undersized. The machined highlights trace the high points of each spoke cleanly, so mud wipes off without hiding the detail work. Matte or satin body colors — desert tan, military green, flat gray — let the machined faces read clearly. Brighter whites and blacks work just as well.

Fitment
This wheel runs the 4x156 bolt pattern, which covers a range of half-ton trucks and SUVs depending on hub bore and offset. ET+0mm offset is typical for stock-height fitments; leveled and lifted trucks may want different offset/backspacing combinations to clear larger tires. A hub-centric ring is recommended when the wheel hub bore is larger than the vehicle hub.
About the GLOSS BLACK MACHINED Finish
MSA Offroad Wheels has focused on the UTV segment long enough to understand that side-by-side fitments have different demands than full-size truck applications — different load ratings, different offset requirements, different terrain abuse. Their catalog stays purpose-built rather than adapted from passenger-car platforms, which shows in how consistently their bolt patterns and backspacing specs translate to real-world fitment without surprises.

Questions We Get
Will this fit my UTV?
The M45 Portal is drilled 4x156, which is the standard bolt pattern for most Polaris RZR and Ranger models. That said, always confirm your specific year and trim — offset, hub bore, and brake clearance can vary even within the same model family. Bring your vehicle details to us and we can cross-check before you order.
Do lug nuts come included?
No, lug nuts are sold separately. UTV wheels often require a specific seat type — conical, ball, or shank — depending on your hub configuration. Grabbing the wrong lug nut is one of the most common fitment mistakes we see, so it's worth confirming the correct spec before you buy.
