8x170 is the Ford Super Duty pattern. You will find it on Ford Super Duty — F-250 and F-350. We stock 3,271 wheels drilled 8x170.
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.
