"D's" pronounced (dee's). Early in the words meaning, "D's", "Dubs", and "44's"four-fò's
were all references to the number 22, which in the late 90's and later refers to automobile wheel (or "rim") diameter. 22" is 6 to 10 inches larger than the average rim diameter. This extra margin of length provides external reference to person's wealth. Later, "dub's" or "d's" evolved simply as a reference to oversized wheel diameters. Diameters currently span as large as 40" in the continuing effort for individuals to show marginal length over the common man. This is consistent with the historical recurring theme that wealth can be measured by quality or size of wheels. Interestingly during the 1990's and late 1980's trends began with undersized rims, spanning from 8" to 10" total diameter. Reasons for this change are unknown. In the song "throw some D's" they discuss the apogee of ghetto prestige by showing that Richboy, the singer of said song, is able to obtain whatever wheels he so desires. Further other people should be so lucky as to achieve his socioeconomic stature.
