A Honda Civic Type-R have either 4 or 5 wheel studs per wheel. Therefore, you need corresponding 4 or 5 wheel nuts per wheel. If your Type-R has been modified, you will need to verify the thread pitch. You can easily figure out the thread pitch with a simple thread pitch gauge, or you can simply take one of the lug nuts to the local hardware store and spin it onto the studs they have on hand.
How Much Torque Do You Need for Honda Civic Type-R Lug Nuts?
The 2013-2025 Honda Civic Type-R lug nut torque spec is 127 Nm (94 ft-lb) and the 1997-2012 Civic Type-R lug nut torque spec is 108 Nm (80 ft-lb). In most cases, your tire installer will have a recommended torque number. Set the torque wrench to the manufacturer’s recommended value. Then simply turn the wrench handle until it reaches the torque mark. Then, tighten the new Type-R wheel nuts a quarter turn at a time following the crisscross sequence (in a “star” pattern). This ensures that the Honda Type-R lug nuts are forced evenly.
What is the Honda Civic Type-R Lug Nut Socket Size?
The most common socket sizes for Honda Civic Type-R lug nuts are 19mm (3/4″) or 22mm (13/16”).

If your Type-R don’t come with special wheel locks, then you can easily find the correct Hex sockets or wrenches to install or remove the lug nuts.

What Kind of Honda Civic Type-R Lug Nut Do I Need?
Depending on whether the end side of the lug nut is sealed, the Honda Civic Type-R lug nuts are split into open-ended types and closed-ended types. The wheel studs are the threaded bolts that protrude through the holes in your wheels onto which you would thread your lug nuts. Open-ended lug nuts allow the studs to stick out. This looks cool in many racing cars, but an exposed lug stud is more prone to corrosion.
In this case, BONOSS forged 50BV30 steel Type-R wheel nuts are close-ended. Closed-end wheel lug nuts can prevent rainwater and debris from entering the studs. Particularly, BONOSS forged 50BV30 steel wheel lug nuts give neutral salt spray resistances exceeding 500 hours, which makes it ideal for fasteners in the automobile industry. The advanced multi-layer coating improves the scratch resistance ability. Never worry about being difficult to remove these wheel nuts.
