Biggest problem you're going to run into with the crappy stock lug nuts is that the caps will separate from the nuts, thereby leading you to have to hammer a socket on to remove the nut. Best thing to do is to buy a set of one piece lug nuts from McGard or Gorilla and call it good.

 

Whats the correct size for the wheelnuts?
Found this kit from gorilla: (...deleted)
Will it fit ?

 

Those won't work, the threads are metric M12 x 1.5

It was capitalized..... I thought, Rusty Wheelnuts, it was a guys name.

I'm not sure why factory lug nuts are made that way. Cap separation is always a problem 8 years down the line. I always put some motor oil on the stud or they rust on up here in Minnesota. I have use both McCord and MrGasket lug nuts, but the first time you put them on the car, the chrome gets scratched where the nut contacts the wheel and you are right back to the ring of rust like you have right now. Someone must make a solid stainless lug nut. (if not I'm going to tool up and start) The only thing you gain is the nut is solid and won't have a cap that comes loose leaving an odd sized nut that is hard to remove.

 

IIRC stainless steel is not as hard and they can shear off.

 

Stainless is usually tougher than steel. Stainless is a mixture of nickel and chrome. The biggest problem with some grades of stainless is it's tendency for threads to gall up and jam. Most stainless nuts are 18-8 stainless.

 

FWIW, the McGard lugs I've got on my XJ are about 8 years old with no rust.

 

Thanks for the info, I think I'll go for Mc Gard then, expensive but are guaranteed for life not to rust, chip, or peel!

I think they don't make stainless steel lugnuts because the mounting threads on the axle are galvanized steel, stainless on steel can cause fretting and damage the thread.

 

You could always go for something like these:

Plus you'll drop some unsprung weight. Just remember to use lots of anti-seize on the threads.
