The simple answer is there were no MBTs (Main Battle Tanks) used in WWII. The Main Battle Tank was a concept that developed during the could as Armored technology evolved to a point that Medium Tanks could mount guns able to effectively penetrate any practical armor at long range. This made the concept of a Heavy Tank, heavily armored, armed, but slow, obsolete as now tanks smaller, faster, and more maneuverable could take them down with relative easy.
In many regards the first Main Battle Tank was the British Centurion, which was developed in 1945 and variants of which are still in service today, but it never saw combat service in the Second World War. The first Soviet MBT was the T-64, as it's predecessors were all designed and classified as Medium Tanks. The First American MBT was the M60, unofficially known as the M60 Patton, though I do remember hearing somewhere that designating the M60 as an MBT was done more as a publicity stunt than anything else and it was effectively just a Medium Tank, however I have no sources for this.
