Flat Tire

On Saturday I ran into the curb and got a flat tire.  We were not too far from home but it was raining and kind of a pain.  Bob accidentally broke a tool while trying to change it so we needed to go home to get the replacement tool.  Luckily a friend was able to give Bob a ride back to the house (thanks Kelli).
Anyway with the spare on I wasn't too worried about getting it fixed.  Little did I know getting new tires can be a big pain.  First off you should know we don't have a standard size tire.  They are extra big.  Not our choice, just came with the car.  So I went to three tire places on Saturday, two were closed and one didn't have the size we needed.  We drove to church the next day with the spare.

I got up bright and early Monday morning and went back out to one of the other tire places to get a new tire.  They told me I needed to replace all of them!  Not because they were worn, they still had plenty of tread.  But because we have AWD and all of our tires need to be exactly the same or it will ruin the transmission.  I had never heard of such a thing before.  He was charging me almost $900.  What I thought was going to be a hundred dollar fix was quickly turning into a grand.

So I turned around and left and now we still have the spare on and are in hunt for a used tire or just something cheaper.  Does anyone out there know more about this?
The spare tire.  It looks so tiny.  It is smaller than the others and feels very weird to drive.
The tires we have on the other wheels.
