5x139.7 (5x5.5) is the classic full-size pattern from the pre-2012 Ram era. You will find it on Ram 1500 and older full-size trucks and SUVs. We stock 2,524 wheels drilled 5x139.7.
Measuring is simple: count the studs, then measure the diameter of the circle they sit on. Five studs are measured from the far edge of one hole to the centre of the one two holes away; six or eight studs across opposite centres. Ordering the wrong pattern is the most common fitment mistake — if your measurement falls between two patterns, confirm with the vehicle's spec sheet first.
