lugnut question

hey gang! it's been a while. hope everyone is well. I have a question about lugnuts. I have a 99 wrangler sahara. can someone please tell me which size i'm supposed to be gunning for? I just bought the 1/2 x 20 set, but they dont fit. Well, actually, they fit on the peg, but my tire iron isnt big enough to turn them.

Any thoughts on this?

J

The standard lugs on my TJ take a 3/4" driver.

sorry to sound stupid, but does that mean I should be looking for a pack that says 3/4 x 20? or what?

Lug Nuts, Conical Seat, Bulge, 1/2 in. x 20 RH, 1.4" Long, Closed End, Chrome Plated Steel, Set of 4

These are what I purchased from Summit Racing when I bought new wheels. $3.95 for a set of 4.

NO!!! They are measured on the Inside Diamter of the lug nut....not the Outside diamter.

I save my back and use a cordless impact gun but only to remove them. You must torque them to prevent over tightening them. Plus some of my vehicles are metric.

ONLY for removal and then after first breaking the bond, with a 1/2" ratchet and 4" ext. and 3/4" socket, which will fit all the alloy/steel wheels without marking

I also use ProComp Extreme alloy wheels with "SPLINE" lug nuts that use a special "KEY" for install/remove (hard to steal that way)

Yep you need a 1/2x20 lug nut which is the size of the threaded stud they screw onto. They can require either a 13/16 or 3/4" wrench depending on who made them.

I've had my TJ nearly 14 years & I haven't used the factory lugnut tool in probably 13 years. My lugnut tool is a 2' breaker bar, 4" extension, & a deep 3/4" socket.

3/4" is so painfully close to 19mm you could use either. (I think 19mm comes out to .748... inches)

The only thing I was going to pipe in with was that my Jeep had 1" wheel spacers when I originally bought it, thus making the lugs a different thread size/pitch. But then I re-read the original post before responding, so it doesn't sound like that matters in this case.

If the lug nuts thread on multiple revolutions (by hand) and don't feel loose, then you have the right lug. The common lug nut sizes are 17mm, 19mm and 21mm and 3/4" 13/16" and 7/8".. You can even buy an impact rated kit from Amazon for less than $30.

Just make sure you torque the new lug nuts appropriately.
