Scary how? A little pressure against the rim on one side, then a soft hit 180 degrees around, and the lugs on to keep the wheel from flying.
One could even back the lugs out if the rim is stuck on the hub center....

 

yeah I guess... kicking it seems a little easier. always works for me...

 

x2 kick the bajeebus out them at the edge of the rim on alternate sides.

 

I had the same issue and used a bigass orange dead blow hammer, worked great! Also, Matt16, I put anti seize on the back of my rims and it helped, but not as much as we would like, still needed a hammer the next time. The third time it was all good though. Which remeinds me, kinda off topic, but I put anti seize on my steering stops and it fixed the zombie dolphin dying creaking noise

 

It sounds like it's pretty cold where you are.... If you have any way to keep the truck in a heated garage long enough to actually warm the rim through and then maybe add some more propane heat to it... then sledge the crap outta it like what has been suggested.

If you've got a -40 windchill then I can guarantee you that it's contracted a crapload. That plus it's seized. I had the problem last winter (but it wasn't quite as cold.. only about 10*). I kept it in a heated garage with a parabolic heater pointed right at the rim from about 2 feet away. I let it sit there for a few hours then I was able to slam it from the inside a couple times and it came off.

 

Oh and that info was for Matt16

 

Cool, I thought it would. Sounds pretty intimidating if you don't know what it is eh.

 

Yeah, for sure, not a nice sound

 

Rubber mallet. I had to get the wheels off my truck a few weeks ago and it took about 10 minutes of whacking the tires (inside out!) as hard as I could. Nice thing about the rubber mallet is you do not damage the wheels.

 

soak the center & behind the rim with PB Blaster & let sit for a couple hours. Then beat the hell out of the TIRE with a sledgehammer.

 

a 2x4 across the rim and a 10lb sledge. Toyota truck wheels are aggrevating to get off sometimes, just like the drums

 

kick it as hard as you can. thats what i do. (the backside).

 

didn't read all responses but I had the same problem trying to do front brakes.

Even a come-along couldn't get mine off so I loosened the nutes about a turn and a half and ran errands until I felt them come free. After changing the brakes I used a ton of grease.

Your truck and the momentum it has going down the road is WAY stronger than any penetrant or sledge.
