It is a 1 1/16" socket - use a 6 point impact socket. Better if you have a 3/4 drive socket with a set. Harbor freight has a reasonable priced 3/4 inch set, does not include six point socket but you can get that separate. Use a good socket and be careful, rounding those lug nuts off will make things go from bad to worse.

 

Toss the OEM tire iron in the nearest trash can. Then get yourself a nice 1/2 breaker bar and a 1/2 socket. It will be MUCH easier to get the lug nuts off with that.

 

Not a 1 1/16 “ socket. A 27mm socket. It’s British, everything is metric. You’ll eat less lug nuts when you use the right size.
And I second the good breaker bar advice.
and when you do them up, 103 lbs of torque, not 80 to 100. Land rovers like precision.

I always make sure if it’s in a shop that I tell them, “no air tools”. They destroy the lug nuts.
I also tend to check the torque when anyone else takes the wheels off. I don’t trust shops not to just do it by feel.

And if you know who put them on like that, makes sure they never get near her again.

 

ordered both sizes they get here tomorrow

 

As mentioned a breaker bar with a long pipe on it will do it. I have a 3/4” breaker from doing my hubs, can’t remember who recommended, but that that sumbitch is sturdy and will handle it. 1/2” breaker bars are tough but that amount of torque on them may break it.

I have a smaller breaker that fits over my 3/8” as well, obviously not for lugnuts, but those lengths of pipe are cheap and really really come in handy with rusty bolts.

 

I snapped (2) 1/2 breaker bars doing my rear hubs. I about crapped my pants both times. Then I stepped up to the 3/4" and worked like a charm. I bought a 3/4" socket set and use that to get my lug nuts on and off.

 

Good excuse to buy more tools 👍🏻

 

Impact guns put nowhere near the power of an adult male (except one of those skinny Jean wearing Seattle types perhaps) with a breaker bar.

I'm quite confident I could remove the lug nuts in minutes, though it might include the studs with em! lol

So that said, I'd advise you to spray some penetrating lube like "PB Blaster" on the bolts overnight. I enjoy the heat then cool tricks of a torch and a upside down can of keyboard duster but on a pretty wheel, we can't do that. You can put a socket on with a piece of wood backing the socket and give it a whap with a a large hammer to sometimes to help the penetrating lube look for a home. You could gently warm the lug nut area with a heat gun and then spray your penetrating lube, sometimes it'll suck some down a little better.

I would advise a hardened socket made for an impact gun, they're generally black in color.

To break it lose, proper size socket (quality counts) and a 3/4" breaker bar WILL break it lose, hell I an easily just spin the stud with that and I'm not a big guy. If you need, cut a 2x4 wood chunk to fit from the socket height to the ground, this will act as a brace so that the wrench nor lug are damaged when you REALLY put some serious weight down. You can roll the vehicle foward or back to adjust the height of the lug from the ground to make your 2x4 fit exact. I don't find this step to be needed but if you feel it helpful, it will assist.

Otherwise, sounds like folks have given ya some good direction here.

 

Soviet Russia Approach!

 

24” 1/2in breaker bar, 27mm socket, and brute strength did the trick.

also soaked them in WD40.

three tires off so far.
