I need to buy a lug wrench because I lost mine. Want to know if anyone knows the exact mm size of the lug nuts on a stock Cobalt SS/TC...?
Hope someone can let me know!


Btw, I did use the search but it didn't give me any useful results.

 

m12 1.5

 

That's the thread size. It sounds like he just wants to know that he needs a 19mm socket.

 

lol....only read the title...not the post

 

lol right, reading impaired hehe

 

This. Yes, thank you.

Appreciate the info.

 

Why would an American car use a 19mm socket? It's a 3/4!

 

You obviously haven't worked on a cobalt. Lol everything is metric.

 

This.

Every damned thing.

Might as well measure the pipes in millimeters. Everything else is!

/me goes out to set his car to KMs, just for ***** and giggles.

 

I just put my summer tires on and you are 100% right.

It clearly says 19 right on it.

I used my 3/4 socket in spite to change them though.

 

I always use a 3/4" socket. Works just fine. I've had 0 problems in ten years.

 

A 3/4 socket will have additional play and may contribute to rounding of corners if you don't have a decent socket. For all intents and purposes though, most people can get away with 3/4" or 19mm, since the lug nuts aren't torqued on that hard.
