What is the lug pattern on a 1988 Toyota pickup?
The lug pattern for a 1988 Toyota Pickup is a 6-lug arrangement on a 139.7 mm bolt circle (6x139.7). In practical terms, that means six studs spaced around a circle that measures about 139.7 millimeters in diameter, equivalent to 5.5 inches between opposite studs. This pattern applies to most US-market and many international 1988 pickups, regardless of 4x4 or 4x2 configurations.
Overview of the pattern on the 1988 model
During 1988, Toyota’s light-duty pickup lineage—known in the United States as the Toyota Pickup and in other markets as the Hilux—predominantly used a six-lug wheel setup on a 139.7 mm bolt circle. This standard is commonly cited across model years for that generation, and it generally holds for both two-wheel-drive and four-wheel-drive variants of the era.
Why the lug pattern matters
Understanding the lug pattern is essential when replacing or upgrading wheels. The six-lug, 139.7 mm pattern ensures wheel mounting compatibility and affects everything from brake clearance to hub fit. If you’re sourcing aftermarket wheels or planning to swap wheels from another Toyota model, verifying this pattern helps prevent fitment issues and safety risks.
Common wheel options and compatibility for this bolt pattern are summarized below.
- 6x139.7 mm bolt pattern (six lugs on a 139.7 mm circle)
- Most aftermarket wheels offered for 1980s Toyota pickups are designed to fit 6x139.7; verify load ratings and offsets for your vehicle
- Check center bore and brake clearance when selecting wheels, especially if mixing parts from different years or markets
When shopping for wheels or adapters, confirm both the bolt pattern and any vehicle-specific requirements (hub bore size, brake rotor compatibility, and offset) to ensure a proper, safe fit.
How to verify your lug pattern
To confirm your lug pattern, you can measure directly or consult documentation specific to your VIN. The steps below outline a straightforward verification process.
- Count the number of lug holes on the wheel hub. For this model year, you should see six.
- Measure the bolt circle diameter by drawing a straight line through the centers of opposite lug holes and measuring the distance. For a 1988 Toyota Pickup, this should be close to 139.7 mm (about 5.5 inches).
- Convert the measurement if needed and compare it to the stock specification for your exact truck variant. Variations can exist by market or trim.
- Consult a reliable source (service manual, dealer, or a reputable wheel shop) to confirm the precise pattern for your VIN.
Accurate verification helps avoid wrong-wheel purchases and ensures proper engagement with the wheel studs and hub.
Summary
For the 1988 Toyota Pickup, the prevailing lug pattern is 6 on 139.7 mm (6x139.7), a six-lug setup standard across most configurations of that year. Always verify the pattern in your vehicle’s documentation or with a professional if you’re unsure, and consider hub bore size and offset alongside bolt pattern when selecting wheels or adapters.
