Lug Nut Socket Size - Caravel 16RB

Hi! New member here. My wife and I are picking up a Caravel 16RB early next month. We're newbies to travel trailers and this forum has been a great source of information - thanks! I do have one question I have not been able to find an answer for, though.

What size socket do I need for the tire lug nuts on our Caravel 16RB?

I emailed Airstream and they said 1/2", but that seems awfully small. I see from another thread in this section that the 19CB calls for a 13/16" socket, which is a lot bigger.

Does anyone who has a Caravel 16RB know what size socket I will need? Any guidance you can provide to this newbie would be greatly appreciated!

I use a deep 3/4" socket (19mm should be interchangeable with that, by the way)

Thanks! I see you have a Flying Cloud 26U. I wonder if the lugs on the Caravel 16RB are different? 3/4" seems reasonable, but Airstream said 1/"2", which seems pretty small.

I'm having TPMS devices installed in the wheels, so I know the wheels will have been recently remounted when I pick up. I want to be sure I can torque them periodically as called for in the manual.

My 2020 International has 13/16” lugs. I was told by my Airstream dealer that they were 3/4”, but I very quickly found out that the dealer was wrong.

If memory serves me correctly, the stud ("bolt") size is 1/2-inch, and the lug nut size is 3/4" or 13/16"--depending on whether or the those stupid tin covers are used on the lug nuts. I think I read somewhere that AS had discontinued them, but I met someone this summer with a 2019 AS which still had them from the factory. (AS is nothing if not consistently inconsistent. Wait until you have to replace screws in door hinges and shelves--and you WILL (have to replace screws in door hinges and shelves).)

I always use a four-way lug wrench for all my vehicles, and that pretty much covers all the typical sizes of lug nuts. I find using the four-way lug wrench easier than a ratchet and extension and socket--I have MUCH more leverage. I then use a torque wrench and extension and socket to tighten the lug nuts to the proper torque, and then I check the torque after an hour or two of driving. And I'm always pretty surprised at how much the lug nuts "loosen" (require re-torqueing) after a couple of hours. (I carry a socket set and not just one socket, so I'm covered there, too.)

Lug Nut Size

I took delivery of a 20 foot Front Bedroom Bambi in early November. I have purchased a Craftsman 1/2" drive torque wrench, a 5" extension and a 13/16" socket for the lug nuts. It fits perfectly. I am thinking that the 1/2" is the drive size. I hope that helps.

Make sure the socket you purchase is a six point. There is less chance of rounding off the lug nut. I use a 1/2 inch breaker bar to loosen them prior to raising the tire off the ground. I believe the torque spec for them is 100 ft/lbs.

Yes to this and add the 6 point socket.

Since we're talking sockets, my lug nuts are 13/16".
I bought one of those cross wrenches that has all four sizes. Couldn't use it, because the Sendel rims have the nuts recessed, you need a six point DEEP, THIN WALL, socket to fit.
But sockets are cheap, relatively, so why not get both 13/16" and 3/4"? The 3/4" will fit the stabilizer jacks in case you think about using a cordless drill to make life easier. "More is more".
Toss in a 3" extension and a 1/2" drive breaker bar from Harbor Freight ($20, get the long one) and lug nuts will fear you!
I use the breaker bars on the hitch also, and all that gear lives under the back seat of the truck.

YES to the six-point socket!

And, YES to the six-point socket--which is an absolute necessity if the lug nuts have those stupid tin covers.

All the four-way lug wrenches I have ever seen (since I was knee-high to a grass-hopper) only have six-point "sockets" on them. The last one I bought (from Harbor Freight) had six-point "sockets."

Guess I'll have to check the Sendel wheels next summer, because a 3" lift kit and 16" tires are looming in our future....

Agree, your solution provides leverage that helps reduce tennis elbow. Everyone know what tennis elbow is? Hint it’s not always associated with playing tennis☹️

Thanks so much for all the helpful replies! This forum sure is has a wealth of information.

I called Airstream and the person who answered at the service department immediately said "I'm sure they are 13/16ths but let me check to be certain." He did, and confirmed that they were 13/16ths. I appreciated his checking to make sure. Thanks for the suggestion that I call.

It looks like those of you were correct who suggested that the 1/2" my email from Airstream referred to really meant the drive size, not the lug size.
