A BE1900 Captain reported tire damage after an apparently normal landing which required that all four main tires be replaced. The antiskid had been turned OFF for this landing.

Narrative

We departed and leveled at our cruise altitude 6;000 FT. Weather condition VFR. Our destination's TRACON clear us for the Visual Approach. I decided to land on Runway 25 since the AWOS report was 320/06; 12C; and the runway was dried. Normal approach and landing but I decided to leave the anti-skid off. After landing and during the walk around tire #2 had a flat spot and #4 was blown at this time #3 was OK but could not check the bottom part. I called Maintenance Control and advised them about the situation on #2 and #4 but I wasn't sure about #3. The flight was delayed. On board nobody was injured and no comments from the passengers. I asked a fellow Captain who was the First Officer if he noticed anything abnormal during landing and taxi to the terminal to which he replied to me everything was normal. When the mechanic came he replaced all 4 tires. He said since the #4 was blown he needs to replaced #3 and since #2 had a really flat spot he needs to replaced #1 as well. In my opinion the approach and landing was conducted in a safe and normal way; and safety was never compromised.
