I feel your pain on the tire issue but I have just bought some of the latest AMT/MPC rereleases and the tires in these kits still have logos on the side walls. I don't understand how Round 2 can do it and Revell can't. I think maybe someone just threw the wrong tires in your Olds kit as all the Revell kits I have bought at least had tires that fit the wheels. Unfortunately, the one thing you can't get through the Revell parts replacement program is tires. Ask me how I know.
