To find the correct information, I recommend:
* Checking your owner's manual: This is the most reliable source.
* Looking at the wheels: The bolt pattern is often stamped on the wheel itself.
* Using an online parts catalog: Enter your truck's year, make, and model into a parts website (like AutoZone, Advance Auto Parts, or Napa Auto Parts). Look up wheels and tires; the specifications will include the bolt pattern.
Once you have the make and model, I can help you find the bolt pattern.
