It's likely that the alloy wheel has corroded onto the steel hub - a common occurance with this combination. A common trick is to loosen the lug nuts (or, in this case, lug bolts) a turn from tight and drive back and forth until it breaks loose.
 
The problem using this technique on a flat tire is that it is likely the tire will be damaged to the point where it is unrepairable. It's also possible that the wheel will be damaged if the rim touches the pavement. You need to be careful using this technique.
 
Alternatively, you could soak the bolt area with a penetrating oil. My favorite is PB Blaster. The problem with this technique is that if the oil gets on the brake surfaces (kind of hard to avoid), the oil will have to be cleaned off. - and if the oil gets on the brake pads, they will have to be replaced!
 
BTW, the plastic pin is supposed to help line up the bolt holes which isn't going to help get the wheel off.

Hi there,
 
I am searching for tires for my 2007 A4 3.2 awd. I live in California (no weather to speak of), but in case I'm out in the rain, something that would handle well would be perfect. Noise and handling are at the top of my wish list. There's so many choices and they all claim to be the best. Any suggestions from other Audi lovers?
 
Thx

Guys,
 
Just had Continental ExtremeContact DSW's put on by local Audi dealer. However, I checked the tire pressure after about a day (cold) and both rear's were set at 36 front driver's at 40 and front passenger at 39.
 
My question is what is the "optimal" tire pressure A4 Quattro, 235x45x17? I don't really care about handling or ride, I care about wear. I had Bridgestone Potenza's on my last, and they lasted only around 30k, and the inner/outter edges were worn down, while the center was fine, assuming from under-inflated tires.
 
I live on the coast of North Carolina, temps currently in the 80's.
 
I am looking for the pressure that gets me the best wear of these tires. Also, would there be a logical reason why the front would be set "higher"?

On every vehicle sold in the US - and I understand this is a worldwide practice as well - there is a sticker – commonly called the vehicle tire placard - that lists the original tire size and the proper pressure for that size. The placard is usually located on a doorpost or in the glove box – but sometimes it is located in the trunk or on the fuel filler door.
 
BTW, it doesn't matter who makes the tire or what pressure is listed on the tire's sidewall, if the tire size is the same as the placard, then the pressure listed on placard is also appropriate.
 
If you follow the vehicle tire placard, then the pressure will be good for the weight of the vehicle.
 
HOWEVER, some vehicles have alignment settings that aren't good for tire wear. For example, many cars specify high camber values which tends to cause inner tire wear. So using the pressure listed on the vehicle tire placard doesn't guarrantee good tire wear - the vehicle alignment has a contribution.

How do you like you tires? I am thinking about getting some Saturday, I have only found them at Pepboys for about a grand with alignment.
