What is the size of the lug nuts on these damn things? is it 18mm? or what Im having a bitch of a time getting them off. any suggestions for that? i was using the thing that came with the car jack but i stil couldnt get it so i got out the ocmpressor and it just spun on the nut.

 

seriously, someone has to know this.

 

I thought it was 18mm, try 3/4 and 13/16.

 

usually they are 3/4 inch nuts....
alot of time the tire iron/jack handle that comes with the car will strip out the heads on the lug nuts

 

i've always used a 19mm.

 

the only size ive ever used was a 3/4
