According to that the aragouet-Bielsa tunnel on spanish side is chains only + winter tyres. . lorries ,buses prohibited.This page lists all the roads affected by snow / ice and is regularly updated. The link on it entitled "Carreteras afectadas (toda la red)." downloads them as a pdf file and gives you the details.
Found it. Spelling is wrong .I have changed it in original post now.
Should remember as we did them both on a Triumph street triple a number of years ago, rode from Orthez through the Somport tunnel, had lunch in Jaca then rode down to Sabinanigo and back over the Portalet.The Portalet is about 30 miles South or should I say East of the Somport. Just had a look less than 30 km.
