Toyota 4Runner Wheel Bolt Pattern
Direct Answer and Scope
For the fifth-generation Toyota 4Runner, which covers model years 2010 through the current production run, the wheel bolt pattern is 6x139.7 millimeters. This pattern is also expressed as 6x5.5 inches. The designation means the wheel has six lug holes arranged on a circle with a diameter of 139.7 millimeters. This specification applies to the standard wheel fitment for the 5th generation 4Runner, though it is always prudent to confirm the exact trim and wheel package for a specific vehicle since accessory or aftermarket wheels can introduce exceptions.
Qualification by Generation and Market
The 6x139.7 bolt pattern is not universal across every 4Runner ever produced. Earlier generations of the 4Runner used different configurations, and a wheel that fits a fifth-generation model will not necessarily fit a first, second, third, or fourth generation without verification. When replacing wheels, the model year is the first fact to confirm. The fifth-generation specification is the most commonly requested reference point for current owners and shoppers, but the qualification is material: a 4Runner from before 2010 may carry a different bolt pattern.
How the Bolt Pattern Is Measured
A six-lug bolt pattern is measured across the center of the wheel from the middle of one lug hole to the center of the hole directly opposite it. On a six-hole pattern, the opposing lug holes are not all positioned at a simple 180-degree alignment in the same way as a four-lug pattern, but the specification still describes the diameter of the imaginary circle that passes through the center of each lug hole. The figure 139.7 millimeters is the metric conversion of 5.5 inches. The second number in a bolt pattern expression is that pitch circle diameter.
Additional Fitment Considerations
Matching the bolt pattern is necessary but not sufficient for proper wheel fitment. Center bore, wheel offset, width, and lug nut seat type must also be compatible with the vehicle hub and suspension. A wheel with the correct 6x139.7 pattern can still cause interference with brake components, fenders, or suspension parts if the offset is incorrect. Factory-lug wheels typically use a specific lug nut seat, and aftermarket wheels may require different hardware. These factors should be checked against the wheel specification before purchase or installation.
Identification Without Documentation
If documentation is missing, the bolt pattern can be identified by direct measurement of the wheel or hub. For a six-lug wheel, measuring from the center of one lug hole to the center of the hole opposite it will produce the pitch circle diameter. The resulting measurement should be read as either inches or millimeters, then compared against the 6x5.5 inch or 6x139.7 millimeter specification. Measurement error is possible, so this approach should be treated as a confirmation rather than a replacement for published specifications.
Practical Next Step
The supported next action for a reader is to verify the model year and confirm the original wheel specification for that exact 4Runner. From that baseline, check any replacement wheel against the 6x139.7 bolt pattern, center bore, offset, and lug seat. If the vehicle has factory wheels that are being retained, no action is typically required. If the vehicle has dealer-installed or aftermarket wheels, measure and inspect them individually because a previous owner or retailer may have changed the specification.
