Noen som vet hva JJ betyr 
Bokstavene har, så vidt jeg har funnet ut, noe med felgens kontur å gjøre. Har bl.a JJ, J, eller K. Men hva de forskjellige bokstavene i praksis vil si, aner jeg ikke...
J, JJ, K, JK, B, P and D : Tyre bead profiles.

No, my keyboard letters weren't stuck down when I typed this. The letter that sits between the rim width and diameter figures stamped on the wheel indicates the physical shape of the wheel where the tyre bead meets it. In the cross-section on the left you can see the area highlighted in red. As far as I know (and this is an elusive topic to find solid information on), the letter actually denotes the shape. For example, here you can see the red highlight is a "J" shape. In this case, this would be a J-profile wheel. 4x4 vehicles often have "JJ" wheels. Jaguar vehicles (especially older ones) have "K" profile wheels. Some of the very old VW Beetles had "P" and "B" profile wheels, although how you could cast a "B" into the rim profile and have the tyres stay on is a mystery to me.....
Now like I said - this is an awkward topic to find definitive data on, so I could be wrong here. If you know better, e-mail me. I'll be glad to update the site. But the rule of thumb is this : if your wheels are stamped 5J15 and you buy 5K15 tyres, rest assured they won't fit.
