Are these wheels with +10mm offset enough to avoid control arm rubbing with a 37/12.5/17 BFG K02 tire on a Gladiator sport with Mopar lift and Rubicon fenders?
The Quadratec Morphic II Wheel features a +10mm offset and 5.2-inch backspacing, which places the tire closer to the suspension components compared to lower backspace options. When paired with a wide 37x12.50R17 tire, this setup can cause rubbing on the factory control arms during tight turns. Grab a set of wheel spacers or wheels with a more negative offset (around 4.5 inches of backspacing or less) to completely clear 37-inch tires!

Will I have issues rubbing the lower control arms on a Jeep Gladiator Sport with a Mopar lift and rubicon fender flares looking to run a 37/12.5/17 BFG AT tire?
Yes, you will very likely run into lower control arm and sway bar rubbing issues with that specific setup.
The Quadratec Morphic II Wheel features a 5.2-inch backspace. When paired with a wide 37x12.50" tire, that higher backspacing tucks the wheel and tire inward closer to the frame and suspension components. Even with a Mopar lift and Rubicon high-clearance style flares clearing the outer body, a 12.50"-wide tire on a 5.2" backspace wheel typically rubs the factory lower control arms at full steering lock.
To clear 37x12.50" tires safely on a Gladiator JT without rubbing your control arms, you'll want to look for a wheel with a lower backspacing (ideally around 4.5 to 4.75 inches) or a negative offset.

Will these clear suspension components while remaining tucked under the fender on an 18 JKU with 2.5in lift and 33-35in tires?
Yes, the Quadratec Morphic II Wheel 17x8.5 with 5.2-inch backspacing is specifically engineered to provide clearance for larger tires while keeping them tucked as close to the factory fender flares as possible on a Jeep Wrangler JK/JKU.
For your 2018 JKU with a 2.5-inch lift, these wheels will clear your critical suspension components (such as the sway bar links and control arms) with tires up to 12.5 inches wide (typically a 35x12.50R17 or 315/70R17).
Internal Clearance: The 5.2" backspacing (+10mm offset) moves the wheel further outward than the factory wheel (which has roughly 6.25" backspacing). This provides the necessary gap to prevent a wide 35" tire from rubbing against the frame or sway bars during full-lock turns.
Fender Coverage: On a JK/JKU, this specific backspacing is often considered the "sweet spot." It allows the tire tread to stay flush with the edge of the factory fender flare. Unlike wheels with 4.5" backspacing that often "poke" 1–2 inches past the flares, these maintain a more tucked, factory-plus look.

are these wheels strong enough for offroad use?
Yes, the Quadratec Morphic II Wheel is specifically engineered for heavy-duty off-road use. It is cast from a strong yet lightweight aluminum alloy and is designed to withstand the physical abuse common on technical trails.
