I have just received my first delivery of Pirelli's first foray into re making the P7 tyres of the mid '70s, with 2 new tyres that are homologated by Porsche with the N4 designation
They look great, thanks for the pic. Do you or anybody else know what was factory fitted in late '76? Mine has Pirellis on the front & Dunlops on the rear, sounds odd but the grip is ok in the wet & dry. Thanks
The sizes here were fitted to a few 1976 model year Carrera 3.0s (VIN 911 66........) that came with option M395. This option included a re-calibrated speedo to compensate for the lower rolling circumference of these tyres.
1977 model year Carrera 3.0s with option M395 came with 16" Fuchs with 205/55 & 225/50 P7 tyres. In this case there was no need for a re-calibrated speedo as the 16" wheels with the low profile tyres restored the original rolling circumference.
If Pirelli remake the P7 in the 16" sizes I would definitely fit them to my Carrera 3.0

Interestingly, my '76 built car has the tyres mentioned above but the speedo over-reads and assume it's been there from new as l have all mot's & fsh stuff etc from day 1. Having had the car for years, l only noticed the over-reading since the introduction of those roadside read-out speed thingys and don't have a satnav wotsit
The Porsche option codes often changed from year to year. In 1976 M395 was Pirelli P7 tyres and could be fitted to a number of 15" rims. In 1977 M395 was Pirelli P7 tyres fitted to 6&7x16 Fuchs.
Andy,
Thanks for spotting the error, I have edited the post.
Fairly sure mine are 16'' x 7 front & 8 rear, it's a sport model & the coa mentions forged alloy rims but no size, can you help solve the puzzle please? I have no experience unlike you guys. Thanks
