Does anyone know when Ford changed the bolt hole pattern from imperial to metric measurements ?
My truck is a 1988 so I know it was imperial then. I am shoping for some better rims and it would be
helpful to know.
Thanks

 

1996 was the last 5 x 5-1/2 on a F150.

 

You can also correct title by clicking edit button on original post.

Then, "go advanced" button & this will show title bar.

If you want.

 

99 was the first year for metric. so you will want to look at 97 or older for rims to fit your 88

 

For F-Series over 8500 GVW, 1998 was the first year for Communist sized wheel lugs. Under 8500 GVW, it was 1997, the first year of the bubble-shaped F-150.

E-Series trucks use 9/16-18 wheel lugs to this very day in 2022!

 

there was no 88 full size f250 or 350 trucks.
he has a F250, so his year range is 97 and older.

 

To fit your truck correctly you want a '96 or older F150/Bronco wheel, the 5x135mm wheel used on some later F150s has the wrong offset so even if you did make it bolt on there would be tire rubbing issues. Some Dodge and Jeep vehicles also use the 5x5.5" bolt pattern but again I have found the wheel offset isn't ideal and in some cases the hub opening diameter is too small.

 

The 92+ factory forged alu Alcoas are inexpensive and common still. Best bang for buck to me in terms of strength, weight, and appearance.

 

thanks, did not know I could do that

 

he has a F250 with 8 lug wheels. F150 and bronco 5 lug wheels wheels will not work

 

Well I missed that point obviously.
