Keep away from the P5 Nick, you just pay extra for the “retro” look but basicaly you are bying a tyre that was designed 30 years ago…
And you travel a lot with this car, so good modern tyres is a very good idea.
To complicate things even more for you, how about considering going to a 215/65 R50 dimension?
That’s what I did and I am very hapy with.
They look nicer (in my opinion at least) and the norrower sidewall improves handling.
Also consider ones with Rim protection, usefull and also looks nicer.
