Does a 07 vintage Pontiac have same swollen lugnut issue as newer fords? I noticed my 3/4” socket is real tight on the lugnuts. Was at junkyard and found some nice wheels but 3 of the 4 lugnut are semi rounded over. Guy had a 3/4” 6 point socket but it would not fit on lugnuts. Tried a 13/16 6 point and it spun. So the hex is messed up. Will pounding on a 3/4” 6 point work? Or try a 20mm socket? That’s .780” ---

Any lug nut with a cap can have that problem. My first car was a 1977 Olds and I had that issue. 19mm is just a hair larger than 3/4 so you could try that, but I have +.5mm wheel sockets to remove problem nuts (19.5, 21.5, 22.5). Just had to use the 21.5 yesterday on a Toyota. ---

The only two lug-nut related items I can find for an 07 Pontiac is a caution when using non-oem lug nuts/covers, and that the cap can crack if the wrong size (length) socket is used, which can then corrode the lug nut it covers. Googling PI0655A might provide further info. ---

19mm is .741”. 20mm is .78” ---

I got a 20mm socket. It was snug. Had to tap socket onto lugnut. A 19.5 may not have fit. Lugnuts came off. Got the set of 4 wheels/tires for $57 ![image](https://global.discourse-cdn.com/cartalk/original/3X/9/f/9f1ea98be9e34da99bffc186778f9bf9ba9feb34.jpeg)
