I think the tires are the Conti's. At least they look similar to my eyes. I remember when all the AMT tires on any of their models were the Firestones. As a kid I figured that they must be the best tire made...at least until my mother bought a new 68 Falcon. Then I discovered what crappy tires they truly were. I put some Kelly-Springfields on ASAP!
Also, I did a mental count of all the models that I remember building as a kid. I must have been stoned all the time and didn't even know it. It comes out to being between 275 and 285. I painted everyone of them of course, and some of them were disassembled a couple of times as I modded them after building them stock. Sometimes I gave them my version of a restoration, as my skills improved. Well, they had to reflect my increased ability as well. So apart they came and a new paint job, mod parts, speed parts, whatever. I would even buy some MRT tires through the mail. One order I remember buying a dozen sets of wide tires. And another source that I had I could get the wide wheels for the tires. Of course that meant that I had to disassemble the car and radius the wheel opening, or push the fenders out to accomodate the wider tires and wheels...
