I am trying to help my brother find out if the AR Chrome Atlas wheels on his '97 F-150 would switch to a '01 Screw. I know that the bolt pattern is the same, but under the application guide on the website it says "Switch to 14x2.0 lugs in 2000-on " Curious if anyone knows what they are talking about there?

Thanks

 

Sometime in 2000 Ford changed from 12 mm lugs to 14 mm lugs. If the bore on the 97 wheels is bigger than 14mm you shouldn't have a problem. There's actually a decent amount of discussion about this topic so you may try searching for some more info. Good luck -

The stud bore will be big enough, the only thing he'll have to do is to buy some new 14x2.0 lug nuts. This has been discussed to death so theres lots of posts about it, but they will swap over.

 

If the AR rims on the 97 can be switched to 01, then can the 01 factory rims be put on the 97????? I have this exact setup.

 

Hello?

 

The bolt pattern is a 135 x 5 for the 97 and the 01.

The stud size changed 29-NOV-99, so the front part of the 2000 MY had 12 mm studs, the second half had 14 mm.

If you are moving a set of stock wheels from a 01 to a 97, then it will work with the stock lugs you have, as long as they look correct ( the open stock type for the center cap type, vs the L type for the chrome cover on the same lug ).

It amounts to ~ 2mm additional room around the studs, but the wheel is hub centric, so it is not a stability issue, the hub is centering the wheel, and taking the weight, not the lugs. The lougs just stop the wheel from falling off.

 

**************************************************
I measured a 2000 rim and the insets have 15mm diameters not 14mm and the total change in circumference is thus 1mm*2 *Pi or about 6.4 mm. The hole for the hub is identical for my 1999 wheels so thanks for your confirmation! I have lug nuts that use washers so in the future I will try and find a 12mm lug nut with a greater seat.

Anybody know where to get 12mm lug nuts with greater seats than the stock 1999's?

You measured the hole in the wheel, which does need to be slightly larger then the stud size. So a 14mm stud needs a hole larger then 14 mm to allow it to go on, without trying to thread it in. Thus the additional diameter of the hole on the wheel itself.
The washer is much larger then the additional 3mm, and many members here have used the stock 12mm lug nuts with the newer 14 mm stud size wheels, without issue. The lugs from your stock wheels would be a good enough test. I don't have the ability to measure my old stock lugs at the moment ( they are in Chicago, and I am in Detriot at the moment ), so once I get home, I'll measure the diameter of the washer, to give you an idea of how large it is. BTW: Try the formula for diameter, not cir. The cir does not tell you much ( without having to work it backwards to the diameter of the hole ).

 

Thanks sscully.

Umm I made a dumb mistake in the circumference. Since I used the diameter it's d*Pi or about and 3.14 mm around the larger hole.

This somehow translates into less pressure being applied to the wheel by the nut and its seat. I suppose the area formula should be used...

I doubt that it makes much difference either so I won't worry about it. I'm putting the wheels on this weekend.
