Hi
sorry your right on the width Im not sure if 185 was an option. I had Marks old wheels so took the same size of tyre he had, I thought they were standard. I think the extra 20mm was simply to get more rubber on the road.
thanks

That makes sense. I think that the 195s are a bit big, but that means 5 new tyres if I change.

Hi
I would suggest taking Porsche s recommendation that they have recently done. Porsche are homologating the Pirelli Cinturato range of tyres for their classic cars.

The Avon CR6ZZ are great tyres

But Porsche have tested the CN36 range and given them their seal of approval with the N4 marking

So out of interest, what is the right size for a 1975 914?

The 1975 914 was fitted with 5½ J x 15 rims and the original tyre size fitted at the factory was:
1.8 : 165/80 SR 15
2.0 : 165/80 HR 15
Great guide from Porsche, but it doesn't list the 914 (914/4), just the 914/6

I went cheapskate and went 185/65 in the end. Let's hope we don't scrape on the ground too much!

Maybe they forgot they had made a 4 cylinder one
However i don't suppose it matters because they fitted the same tyre
