Well I don't think iptables is the one that resets the number of bytes. The information is probably retreived from /proc/net/dev. I don't know what the largest value is, you would probably have to browse through the kernel code to find out what sets and resets this value.
I think it's an unsigned long (4 bytes) which would allow it to go up to 4GB's.
