Auto sleeper Pescara tyre size

Hi everyone
Not been on for a while but will be taking the motorhome out of storage at the end of the month and I know it needs two front tyres, I think they are 15inch but does anyone know for sure what size they are so I can get the ball rolling??

1998 Pescara 1.9 Peugeot

I'm not aware of any other Auto Sleeper Pescara owners on the forum but I could be wrong? In fact I've only ever seen a couple of Pescara's and they were at shows so they do seem quite a rare motorhome, maybe someone like Peter Brown who's involved in ASOC and has a wealth of info or one of our moderators roli could possibly offer some advice?

Sorry I can't help
