As a bonus there are currently 2 tyres in the size 205/70VR14 that you would consider fitting Michelin XWX - The OE Dino tyre https://www.longstonetyres.co.uk/205-70wr14-michelin-xwx.html and Pirelli Cinturato CN36 https://www.longstonetyres.co.uk/205-70wr14-pirelli-cinturato-cn36.html They are both great, but there is nothing else worth considering. You would only buy anything else because it was cheap, and you dont mind your car not being as nice to drive.
These wheels would fit an unflared 246GT? I generally prefer more sidewall as the roads near me can be quite bumpy but it would be nice to throw some sticky 16" on for certain applications.
Well i wouldn't choose to fit 16" wheels on a Dino. However if i were forced to then those P7 would be the best tyres. https://www.longstonetyres.co.uk/pirelli-collezione/cinturato-p7.html
