You can use the end of the tire iron to remove the lug bolts off a 1999 Mazda Protege DX.
Lug: 5X114.3 assuming lug pattern
I believe it is 4x100. Most civic and corolla wheels should fit.
My 2002 Tribute has 19mm lug nuts.
The lug nut size for a 2006 Mazda Miata is typically M12x1.5. It's important to ensure that you use the correct size to avoid damage to the wheel or lug nut threads. Always consult the owner's manual or a professional if you're unsure.
12mm x 1.5 is the size you are looking for. This fits the Mazda 3, 6, 5, rx8.
the lug pattern is 4x100 so cars like Mazda protege and Honda civic
