Abodys and 15" ralley wheels

Im planning on buying wider wheels for my Duster, the ones in the back are just 245. Im thinking of 295 and a Panhard bar on the axle!

The thing is that i have been looking around for tires that are 295 for 14" wheels , but they seem to be scarse as dont find any! :)

So then i guess i have to go with 15" wheels, does someone have this setup on their car with ralley wheels or any other wheel type ? Would very much appriciate pics of the setup and what kind of tires you run with!
By the way , were ralley wheels offered in 15" with the small bolt circle?

Thank you! :)
