Porsche 914 tire size
Original tire sizes for the Porsche 914, model years 1970, 1971, 1972, 1973, 1974, 1975 and 1976. Trim levels and wheel packages change the size within the same year, so confirm on the door-jamb sticker before ordering.
Check before you order. The surest answer is the tires on the car right now: the size is molded into the sidewall. The placard inside the driver's door tells you what the factory fitted. Our guide on reading a tire size shows exactly where to look.

What Porsche approves
Porsche-approved tires are marked N0, N1, N2 and so on. The number is the generation of the approval, not a quality grade.
Porsche tests each tire against the specific car and raises the number every time the spec is revised. Mixing an N0 on one axle and an N2 on the other is not recommended, and on 911 models the front and rear tires are usually different sizes.
Brands that carry the approval
Written on the sidewall as: Michelin Pilot Sport 4S (N0), Pirelli P Zero (N1).
The drawing carries the sizes we list for this car, so you know what you are looking for. The placard on the car is still the final word, and it is the only place that gives the cold pressures: the number molded into the sidewall is the maximum the tire can hold, not what your car wants.
What those tires cost
