wheel lug sizes

[T2urtle]

i'm going to carrying a breaker bar with me in my trunk, just in case of flats and such for myself and friends.

I know my nissan is a 19mm socket. But what are the other general sizes i would need to say over 90% of the cars out on the road. Assume they are stock lugs and not tuner lugs or ones with wheel locks..

all my cars were always 19mm.

All mine have been 19mm too

My Honda and Subaru are both 19mm too.

i know there is another size.. because one time some borrowed my breaker bar with my 19mm socket and it didn't fit.. so there is another size out there...

According to Snap on the most popular lug nut sizes are (17, 19mm / 3/4", 21mm, 13/16" and 7/8")
