I have a 2000 f150 v6. I recently purchased a set of Atlas wheels off ebay, which included lug nuts. When Firestone was mounting the rims on the truck they seemed to fit on the studs fine, but the lugnuts were too large. I have a 2000 f150 which i believe is supposed to use a 14mm lug, which I had and was too large. It looks like a 12mm stud. If the holes in my rims are for 14mm studs, and I only have 12mm studs on my truck will the rims work loose, or is this how it is supposed to be. Im just confused. Anyone want to shed some enlightenment upon me. Thanx

 

This discussion has come up before because so many people buy used wheels for their truck.

It seems that you can use 14mm stud wheels on a truck that came with 12mm studs, but not the other way around. Ideally, you'd be using 14mm studs, but you shouldn't have any problems.

 

IN the middle of the 2000 model year assembly, the lugs were changed from 12 to 14mm.

Since the wheels are 135mm hub centric (not bolt centric), you can use the new wheels on your truck. Just go buy some 12mm bolts, and don't over torque them.

 

Well 18 years later and I just ran into this issue twice with my 2000 F150. Picked up some new rotors and had to bring them back due to wrong stud size (14mm).

Fast forward few months, got some new wheels and they need there own lug nuts, and they send the 14mm lugs. Now I have to have them send the 12mm. I thought it was a fluke issue with the rotors, but this threads helped me solve the issue. Why would ford switch the lugs? Were the 12mm to weak lol?

 

I have a 2000 ford f150 that I'm trying to take the tires off so I can replace the brakes. I have a 13/16 lug wrench and it wont fit into the slots where the lug nuts are, am I doing something wrong? They seem to be inside of the rim, and my lug wrench wont fit in there.

 

Use a thinwall socket and breaker bar.

 

They are probably metric and not 13/16".
