There unfortunately isn't a guide to tell us the size needed for your specific trailer, but it's really easy to measure for the correct size lug nuts. You'll want to use a set of calipers # PTW80157 to measure the diameter of the wheel stud, including the threads and then measure the pitch by counting the threads in one inch of space on the stud. The most common sizes are 1/2"-20, 9/16"-18, and 5/8"-18. The 1/2"-20 wheel studs are typically used on small-medium duty trailers whereas the 9/16"-18 and 5/8"-18 wheel studs are used on larger duty trailers. I've attached a few of the most commonly used lug nuts below, but if you want something a bit different just let me know your preferences and the size needed.

Chrome Trailer Wheel Lug Nut 1/2"-20 Closed Short # 12CLN
Chrome Trailer Wheel Lug Nut 1/2"-20 Closed Long # 12CLN-L
Chrome Trailer Wheel Lug Nut 9/16"-18 Open # 6-53
Chrome Trailer Wheel Lug Nut 5/8"-18 Open # X1148

I can end this debate for you real fast! Trailer tires, which will have an ST in front of the size, should always be inflated to the maximum psi indicated on the tire. Trailer tires usually do not have a recommended and maximum psi indication so I am…

Answer 8

You will want to stick with the same style of lug nut, so if you use 90 degree lug nuts, stick with that. The reason is the taper on the 60 degree lug nut is steeper, so there could be fit issues depending on your trailer wheel, as they are designed…

Trailer wheel lug nuts that are 1/2-inch inside diameter typically have a 20-TPI thread pitch (20 threads per inch). Most lug nuts also use a 60-degree-coned profile like #CE11051, but a 90-degree like #STN569 is also available for 9/16-inch studs.…
