lol I had this same problem i have stripped like 6 of those. for me the 19 worked best... anyways if the come off just go for it. I honestly beat mine to heck, idk how the guy got those on but the one just wasnt comin off... I drilled the stud out and got a new one. Take that you SOB. but def get some new ones. I just got some 31s on wheels from a guy for 200
and he gave me lugs so, yayyy! too bad I dont have neough for all 5 hahah.
