How early can you renew a combo card? (EAD/AP)

[MM_V]

I have a combo card (EAD+AP). Per USCIS, I can file the I-765 to renew my EAD 180 days prior to it's expiration. Can I also file the I-131 to get the Advance Parole at the same time i.e. 180 days prior to AP expiration?  My intent is to get a combo card again as it is easy to carry .  But if that puts the EAD at risk by 2 months, I would rather go for separate docs.

Reason why I ask this is because I have read in few websites that I-131 should be filed only 120 days prior to expiration.

The below site says if you want to renew as a combo card, file both applications no more than 120 days prior to expiration date.  But other websites say you can file both applications together as early as 180 days prior to approval.
