5x150 is the newer Toyota full-size truck pattern. You will find it on 2007+ Toyota Tundra and Land Cruiser. We stock 819 wheels drilled 5x150.
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 center of the one two holes away; six or eight studs across opposite centers. 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.
