Measuring and Identifying Bolt Patterns
Correctly measuring your tacoma bolt pattern is crucial for proper wheel fitment and vehicle safety.
An incorrect measurement can lead to serious issues like wheel misalignment, unwanted vibrations, or even dangerous accidents. For Toyota Tacoma owners, understanding how to measure bolt patterns accurately is vital for maintaining and upgrading their trucks.
Step-By-Step Guide For Determining Your Bolt Pattern
- Step 1: Count the lugs or bolts on your Tacoma’s wheel hub. Most Tacomas have either 5 or 6 lugs, depending on whether they’re a 2WD or 4WD model.
- Step 2: For 6-lug Tacomas (typically 4WD models), measure from the center of one bolt to the center of the bolt directly across from it. For 5-lug Tacomas (typically 2WD models), measure from the center of one bolt to the edge of the bolt hole across from it (not the center of the bolt).
- Step 3: Note down your measurement in millimeters. Common tacoma bolt patterns are 114.3mm for 5-lug models and 139.7mm for 6-lug models.
Why the Correct Bolt Pattern is Critical for Wheel Fitment and Vehicle Safety?
Safety Concerns
Using wheels with the incorrect bolt pattern can lead to serious safety issues. When the pattern doesn’t match your vehicle’s specifications, the wheels may not mount securely to the hub.
