Step 1 Proposed Wheel Dimensions

Offset (ET) & Backspacing (BS) Auto-Link
Overall Lip-to-Lip Width: 6.00" (152.4 mm) Frontspacing (FS): 1.86" (47.2 mm)
← INBOARD (SUSPENSION / HUB) OUTBOARD (STREET / FENDER) → CL HUB WMS (Pad Face) Bead Width (5.0") +0.5" Lip +0.5" Lip ET +29 mm Backspacing (4.14")
Click any input box on the left to highlight that exact measurement on the diagram above. Hover over any underlined acronym (WMS, ET, CL) for its definition.

Step 2 Tire Sizing & Sidewall Bulge

ETRTO Rim-Width Sidewall Bulge Compensation
Metric Tire (e.g. 195/60R15)
Float / Inch (e.g. 26x8.50R15)
Mounted Bulge: 6.89" (175.0 mm) Overall Diameter (OD): 23.58" (599 mm) Fitment: Bulged / Protected Lip
Tire Sidewall Bulge Mounted Width Sidewall Ht Overall Dia (OD)
Tire section width automatically adjusts (+0.2" per 0.5" rim width delta) to model real-world sidewall bulge and Overall Diameter (OD).

Step 3 Car Clearance Envelope

Measure from Bare Hub (WMS) or Current Mounted Wheel
Mode A: Bare Hub / WMS (Wheel Off)
Mode B: Current Wheel (Wheel On)
SPRING PLATE / ARM FENDER LIP STRAIGHTEDGE ON WMS WMS to Inner Part WMS to Fender Lip
Place a straightedge across the bare brake rotor/drum Wheel Mounting Surface (WMS) and measure inward and outward.

Step 4 Vertical Arch, Caliper & Axle Modifiers

Ride Height Arch Travel, Brake Spoke Clearance & Beam/Hub Shifts
Vertical Tire-to-Arch Travel: 0.96" (24.4 mm) Caliper-to-Spoke Clearance: +0.40" (10.2 mm) SAFE
TOP OF FENDER ARCH HUB CENTER Hub to Arch ROTOR DISC ROTOR HAT U-CALIPER WMS Caliper Overhang Hub Shift
The U-caliper straddles the rotor disc blade; the rotor hat steps outboard to form the WMS.
