Mopar stock steel rims....

I have seen Mopar rims with 3 tabs and 4 tabs . I have seen Mopar rims without any tabs (Superbees) . The tabs are there to grab the hub cap . Cop wheels , diplomat rims and Ramcharger/Ram 15" have tabs for dog dishes even though full wheel covers were employed . Putting wheel covers on slotted rims kinda 'defeats t he purpose of the slots . To answer your question : tabs are to grab the hub cap . The number of tabs really doesn't matter . Caution : 14" and 15" dog dishes look similar but are not interchangeable . Hope this helps , Tom
