European wheel designation ?

Looking at some European wheels,identified as 5J x 15 H2 .

15 = 15" diameter at the bead.That's obvious.

5J = 5" wide ?

What is H2 ?


These are spacesaver wheels,I want to use with regular tires.
5" is ok for the front,probably want to stretch the rears wider.
Any problems there ?

Thanks.

I'm pretty sure the letter tells you the shape of the lip that the Tire seals on.
"J " being the most common one...

 

You are totally right.

J is for the shape of the inner wheel (number 2 on the pic)
H2 is a code for the shape of the inner center of the wheel. (Number 4 on the pic)
