Understanding the 5.39x2 Bolt Pattern Specifications and Basics
The 5.39x2 bolt pattern, also known as 5x108, represents a five-lug wheel configuration with a 108mm bolt circle diameter. This specification is crucial for proper wheel installation and vehicle safety. When you're shopping for wheels or performing maintenance on your 5.39x2 wheel hub, understanding these basics prevents costly mistakes and ensures optimal performance.
What the Numbers Mean
The 5.39x2 designation indicates five lug holes arranged in a circular pattern with a 108mm diameter. The "5" represents the number of bolts, while "108" specifies the bolt circle measurement in millimeters. Many mechanics refer to this as 5x108, which is the standard notation used across automotive applications.
Common Vehicle Applications
Popular vehicles that use 5.39x2 bolt pattern include Ford Focus, Lincoln MKZ, Mercury Milan, and various European models like Volvo S40/V50. Always consult your 5.39x2 bolt pattern compatibility chart before purchasing wheels, as similar patterns exist that may appear compatible but create dangerous installation scenarios.
Technical Specifications
Standard 5.39x2 wheel hub dimensions specifications typically feature M12x1.75 or M12x1.50 thread sizes with a center bore of 63.4mm. The 5.39x2 lug pattern measurement guide shows precise spacing that differs significantly from the similar 5x114.3 pattern used by Honda, Nissan, and other manufacturers.
- Warning: Never attempt to force-fit wheels with different bolt patterns. Incorrect 5.39x2 lug pattern matching can cause wheel separation, leading to serious accidents.

How to Accurately Measure Your Wheel Hub for 5.39x2 Pattern
Learn to precisely measure your 5.39x2 wheel hub to ensure proper wheel compatibility. This tutorial covers essential measurement techniques for identifying 5.39x2 bolt patterns and verifying specifications before purchasing new wheels.
- Prerequisites: Clean wheel hub, digital calipers or measuring tape, calculator
- Tools needed: Digital calipers (preferred), ruler, masking tape
- Estimated time: 15-20 minutes per wheel
Step 1: Clean and Prepare the Wheel Hub
Remove any debris, rust, or grease from the 5.39x2 lug pattern area. A clean surface ensures accurate measurements and prevents errors when checking bolt circle specifications.
- Tip: Mark each lug stud with masking tape for easier identification during measurements.
Step 2: Measure Center-to-Center Distance
Using digital calipers, measure the distance between two non-adjacent lug studs on your 5.39x2 wheel hub. The 5.39x2 bolt pattern should show approximately 4.39 inches (111.5mm) between opposite lugs.
- Warning: Always measure twice to confirm accuracy, as incorrect measurements can lead to incompatible wheel purchases.
Step 3: Verify Multiple Lug Combinations
Test three different lug pairings on your 5.39x2 bolt pattern to ensure consistent measurements across all combinations. Inconsistent readings may indicate damaged or modified hub components.
- Common mistake: Measuring adjacent lugs instead of opposite positions creates inaccurate bolt circle calculations.
Step 4: Check Center Bore and Offset
Measure the hub's center bore diameter and verify wheel offset specifications against manufacturer guidelines in your 5.39x2 wheel hub dimensions specifications chart.
- Expected outcome: Confirmed 5.39x2 bolt pattern compatibility for safe wheel selection. Next step: Consult 5.39x2 bolt pattern compatibility chart for approved wheel options.
Step-by-Step Process for Confirming Wheel Compatibility with 5.39x2 Bolt Circle
Before installing new wheels, verify compatibility with your 5.39x2 bolt pattern by following these critical measurements. This process takes 15-20 minutes and requires basic tools to ensure safe installation.
Step 1: Measure Your Current Hub Pattern
Use a bolt pattern gauge or ruler to confirm your 5.39x2 lug pattern measurement. Measure from the center of one bolt hole to the furthest edge of the opposite hole across the imaginary circle. The 5.39x2 pattern indicates 5 bolts spaced 4.78 inches apart on a 5.39-inch diameter circle. Compare against your wheel's specifications using a 5.39x2 bolt pattern compatibility chart.
- Tip: Clean rust/debris from bolt holes before measuring to avoid inaccurate readings.
Step 2: Check Center Bore Specifications
Measure your 5.39x2 wheel hub center bore diameter against the wheel's center bore. Most 5.39x2 applications require precise centering, so wheels must match the hub pilot diameter exactly. Refer to where to find 5.39x2 hub specifications in your owner's manual.
- Warning: Never force-fit wheels with mismatched center bores as this creates dangerous vibration.
Step 3: Verify Offset and Backspacing
Confirm wheel offset measurements align with your vehicle's 5.39x2 wheel hub dimensions specifications. Incorrect offset causes clearance issues with suspension components and fenders.
Step 4: Test Lug Nut Seat Compatibility
Ensure lug nut seat type (conical, spherical, or flat) matches your 5.39x2 lug pattern wheel hub design.
Step 5: Perform Temporary Fitment Test
Hand-tighten wheels before final torque to verify proper seating on your 5.39x2 bolt circle without wobbling.
Expected outcome: Confirmed compatibility with proper fitment and safe installation.
