What is the lug pattern for a 1977 Ford F150?

The lug pattern for a 1977 Ford F-150 depends on the wheel size and options chosen at the time of manufacture. There wasn't a single standard. You must check your existing wheels to determine the lug pattern.

Common lug patterns for that era included:

* 5 on 4.5" (5x114.3mm): This was a very common pattern.

* 5 on 5" (5x127mm): Also quite common, especially on larger trucks.

To find out for sure, look at your existing wheels. Count the number of lug holes and then carefully measure the diameter of the circle that passes through the center of the holes.
