10lb mallet, hammer and knock the crap out of them and rotate, repeat.
they will come off. driving around, doing burn outs wont do anything. you need side load. go do a lap at thunderhill with the lugs loosened 3 turns. Oh, cant do that, grab the mallet!

Hold On

I notice they are chromed. The thickness of the plating may be making them VERY snug. I agree with Mark. Hammer and rotate. Then find out where on the wheel they are hanging up. It will be obvious.

I agree with the above...

Used to rotate tires/wheels on a dually F350 Mag Spray truck (in my landscaping days!)...

50lb (not that big.. but you get the idea!)sledge hammer, and banging on the tire, rotate, repeat process until it begins to loosen..

The 928 hopefully won't require that kind of persuasion!!

Whenever I encounter a problem getting wheels off that won't budge I just lower the car with the jack and the weight of the car breaks the seal between the hub and wheel.

However if the lug bolts are seized like mine were last spring, it's a whole new adventure, but not a wacky as the dude with the VW in the Honda forum posted by 'Crisis' in an earlier post.

No sawzall involved, just a 3 foot Johnson bar and a torch.

Just an idea, b/c it happened with mine. My car has the extended rear wheel lugs that opiginally came with a spacer, widening the rear stance. When I got the car I also couldn't get the rear wheels off, even with the lugs completely off.

Only when I carefully looked into the lug holes on each wheel could I see an opened end lug nut still on each of the lugs. So basically I had twice as many lug nuts on each wheel

Once I took the inner lugs off, wheels came off like normal

Okay, I should have mentioned to keep the lug nuts on while performing this procedure.

First, make sure they do in fact loosen completely and then put them back on, one or two turns loose.

Then, do the procedure I described.

As far as taking a SLEDGE HAMMER to your car, PLEASE INVITE ME, I think that might be fun, as long as I drive away in MY 928!

And a torch; that’s a really good idea; heat those wheel bearings up, along with everything else down there!

The “back and forth” motion of forward and reverse should get them loose.

If not, try the HONDA method!

PS I did spell brake wrong in the first post!

Try a bottle jack on its side with a 4x4 between the tires with a 2x8 by 12inchs long flat against the tires give it a few pumps and then hit the 2x8 with a good size hammer, rotate, repeat

I'll never have chrome wheels again. They can be such a PITA!

I like the bottle jack idea... That will get them off for sure.

ummmm nobody said impact wrench, that usually works............

Hmm, the jack and scrap wood between the wheels is a good idea. Bottle jack, or a scissors jack maybe. You might even be able to do it with tire pressure if you shim up the wood between the tires really tight with the tire deflated and then air it up (car jacked up, wheel hanging, just touching the ground.)

I got a car from FL that had lived near the beach and the wheels were seriously glued on from corrosion but I was able to get the wheels to pop off with just a scrap of 4x4 and a sledge. Keeping the wood in contact with the wheel lip and not the tire was key, otherwise all your energy just gets absorbed by the tire.

Go back and read some more... it is not the lug nuts that are stuck, it is the actual wheel stuck to the hub. I made that same mistake in my first post thinking he had stuck lug nuts, but nope...stuck WHEEL! Crazy...

Galvanic reaction. Dissimilar metals in contact for an extended duration results in corrosion and a virtual welding together of the metals. Not crazy... science.

Using a sledge hammer: I've done this many times over the years to all kinds of cars with no ill effect. First you hit the tire, form the side, if that doesn't work, put a 2X4 to the edge of the rim and try it that way.

As for using a torch. How hot do you think the wheel bearings get when you take the car for a spirited drive or on a race/DE event? No one said to heat it up red hot, just hot enough to get to get the aluminum to expand a little.

Relax, many of the procedures above have been used for a long time, you just probably never heard of them.

+1 on bottle jack and 4x4,
works on dodge trucks. Maybe a little pressure and hit the wheel with a BIG rubber hammer. Be sure all of the lug nuts and shoulders are off if they break.

The wheels on that car where put on July of 07
