Fitment Notes

• Fits SRW (Single Rear Wheel) configurations only - does NOT fit DRW (Dual Rear Wheel / Dually) configurations
• 8x170mm is Ford's exclusive Super Duty bolt pattern - not shared with Ram, Chevy/GMC, or other HD platforms and not interchangeable with 8x165.1 (8x6.5)
• 130.81mm centerbore provides hub-centric fitment on all listed Ford Super Duty and Excursion applications - no hubcentric rings required
• +18mm offset / 5.75" backspacing is the standard moderate-inboard stance for 18x9 8x170 Super Duty wheels - appropriate for stock-height and mildly lifted F-250, F-350, and F-450 builds; confirm clearance for your specific trim, lift, and tire combination before ordering
• 18-inch diameter supports popular all-terrain and mud-terrain tire sizes including 275/65R18, 285/65R18, and 305/60R18 across all listed Super Duty applications; confirm desired tire size before ordering
• Lug nuts are not included - Ford F-250, F-350, and F-450 Super Duty use M14x1.5 thread pitch with a 60-degree conical seat; confirm seat type before purchasing separately
• TPMS sensors are not included - purchase separately if required
• Sold individually - one (1) wheel per listing

Features

• 12-spoke Street-Loc V.1 simulated beadlock design - the MR315 is Method's street-legal version of the 103 Beadlock race wheel; the 12-spoke layout with Street-Loc V.1 lip undercut and replaceable lip bolts brings Method's competition-derived visual profile to the Ford Super Duty 8x170 platform in a DOT-compliant format; the 18x9 format provides more face surface area and visual depth than the 17x8.5 variant while remaining within the practical tire size range for most Super Duty applications
• Street-Loc V.1 lip undercut simulates the outer ring profile of a true beadlock wheel - provides a structured, purposeful outer lip profile appropriate for Super Duty work truck, towing, and off-road use; the V.1 ring presents a cleaner, less visually dominant outer profile than the V.3 found on the 312, suited to builders who want beadlock aesthetics without maximum ring mass
• All-matte black finish delivers a flat, non-reflective unified appearance - the most broadly compatible color option on the Super Duty platform, pairing naturally with Oxford White, Agate Black, Carbonized Grey, Iconic Silver, Antimatter Blue, and all factory Super Duty color offerings across all trim levels
• Replaceable stainless steel MRW lip bolts installed around the V.1 lip - optional color bolt kits available separately; gold or bronze accent bolts provide an effective warm-tone contrast against the matte black barrel on lighter-colored Super Duty builds
• Bolt-on center cap with embossed METHOD logo for this 8-lug application - provides secure positive retention appropriate for demanding Super Duty towing and payload use
• 130.81mm hub-centric centerbore ensures precise, vibration-free wheel centering on all listed Ford Super Duty 8x170 applications - no hubcentric rings required
• 3,640 lb. load rating for this 8-lug 8x170 configuration - the full heavy-duty rating for the MR315 in 8-lug form, covering all F-250, F-350, and F-450 Super Duty payload and towing requirements within the rated capacity
• +18mm offset / 5.75" backspacing delivers the standard moderate-inboard stance appropriate for stock and lightly modified Super Duty builds - the natural moderate-stance choice that pairs cleanly with 275/65R18 and 285/65R18 all-terrain tires on unmodified and leveled Super Duty applications
• The MR315's 12-spoke full-coverage face distinguishes it from the 305 NV's 12-window design and the 312's deep concave 6-spoke configuration - the 315 presents the most symmetrical and structurally cohesive face profile in the Method HD street series, referencing the 103 Beadlock's full-spoke competition aesthetic in a street-legal format
• Solid one-piece cast A356 aluminum construction with T6 heat treatment provides reliable structural performance for daily driving, towing, payload, and mixed-use applications on all listed Super Duty platforms
• DOT street-legal - suitable for all on-road, daily-driven, towing, and mixed-use applications on all listed vehicles
• Covered by Method Race Wheels' Lifetime Structural Warranty

Product Description

The Method 315 in Matte Black (P/N MR31589087518) is the 18-inch standard-stance fitment of the MR315 for the Ford Super Duty 8x170 platform - covering the F-250, F-350, and F-450 Super Duty (SRW) from 1999 through 2026 in the 18x9 / 8x170 / +18mm configuration. The 130.81mm hub-centric centerbore provides vibration-free installation on all listed Ford applications without hubcentric rings, and the +18mm offset at 5.75-inch backspacing places the wheel in the moderate-inboard stance that is the natural standard fitment for the Super Duty 8x170 platform at 18 inches. The 18-inch diameter supports popular all-terrain tire sizes including 275/65R18 and 285/65R18 across all listed F-250 and F-350 trim configurations without lift requirements.

The MR315 in 18x9 delivers the same 103 Beadlock-derived 12-spoke design as the 17x8.5 variant at a larger diameter that provides more spoke face area and visual presence in the wheel well. Compared to the 20x9 +18mm format, the 18-inch MR315 on the Super Duty platform retains practical sidewall height for towing and highway use while still delivering a substantial aesthetic upgrade over factory Super Duty wheels. In all-matte black the design presents as clean, unified, and purposeful - well-suited to the full range of Super Duty applications from GCWR-rated Cummins tow rigs to daily-driven F-250 Limited trucks where a flat, non-reflective finish is preferred over machined or polished alternatives.

The 8x170mm bolt pattern is Ford's exclusive Super Duty pattern and is not interchangeable with 8x165.1 (Ram/older GM HD) or 8x180 (2011+ GM HD). SRW configurations only - DRW is not compatible. Lug nuts with M14x1.5 conical seat are required and sold separately. Covered by Method Race Wheels' Lifetime Structural Warranty.
