lug nuts?

[intern8tion9l]

i'm trying to order a new set of rims and accessories for my truck, and i got as far as the lug nuts...i have no idea what the thread pitch is, and the guy on the phone said they used numerous pitches in 99. is there any way of figuring this out without going somewhere to size it up? the manufacture date is 6/99

[pipelayerjdh]

Did he give you any options? You could try counting the threads in a CM, then divide by 10 to get the pitch. That should get you close.

[intern8tion9l]

he said either 1/2-18 or 1/2-20 i think

[pipelayerjdh]

OK, if they are standard, you need to count the threads in one inch. Start from the first thread and measure an inch and count to that thread. With numbers that close, it may be difficult to determine. If you end up with 19 threads, it will be hard to decide. Make sure you measure carefully. If you can remove the wheel to get more length of the stud to measure, like 1.5 inches, you can count, then divide by 1.5.

or go to a tire place and get one of each and see which one fits

you probably have the fine thread lugs. my 2000 had the fine. and I think most 01-03 were the coarse thread

Same here, 14mm x 2.0

[lilredpowerstroke]

Its either 14x2 or 14x1.5. I think 01 they changed to 14x1.5 so you might have 14x2
