I need to get a new set of 4 tires for my '68. The current size is P205-R60-15, so they are 205 mm wide, and 0.6 x 205 mm high.

Can I go wider to 225 mm or more? What is the widest you can safely go in a 912 without rubbing on the front fender during a hard turn?

I was also considering maybe going to a higher height like 65 or 70, to keep engine RPMs down on the freeway.

What do you recommend regarding max width and the rule-of-thumb for height.

(fyi - i think there was a post on PCA where someone said they had height of 65 or 70 and it felt weird when driving).
