used tires on new car?

Recently I bought a new honda odyssey. I can see some wornout on the
front tires. while the rear tires are really band new. The car has only
5 miles when we bought it. Now it has about 200miles. Initially I
thought the wornout on the front tires was due to the first 5 miles.
But after we drove 200miles, I still didn't see any wornout on the rear
tires. Thus I believe the front tires were not new when we bought the
car.

(17th week of 2006), and the rest three tires were made in "2006" (20th
week of 2006).

I am wondering what's going on with the car. I feel it is very strange.

 

yeah, so get it to the dealer now, some states give you 3 days to back out
of a contract
