Almost all 914s can run 195-width tires all around. They may rub on the inner front fender, aft of the shock tube, at full lock, but that is generally only done at low speeds and most of us see it as acceptable.

Many 914s, but not all, can run 205-width tires. Often the rear fender lip must be flattened or cut to allow this, but not always. Some 914s won't allow a 205 under one rear fender or the other without pulling the fender out. That's one of the challenges with owning a car that was at least partly hand-built. The same rubbing occurs in the front fenders as the 195s above.

Note that if you use other wheels, the above may change.

Note that 195/50 are quite short compared to the original 165/80 tires. That is good for handling, and shortens your gearing, which are good things. But it makes the ride harder, makes you rev higher to keep up with freeway traffic, and does look a little out of place on the car IMHO.

I've used it in the past, and was happy with the benefits and willing to put up with the downsides.

A better match to the stock diameter would be 195/65 or 195/70.

Not to mention speedo error ,the 195/55 would seem a better choice as there would be zero speedo error for the OP over his 165's.
IMO 205's aren't really safe for the rim width and kinda look a bit odd.

Actually, 195/70 is a closer match than 195/55.

The sidewalls on a 165/80 tire are nominally 132mm tall. (165 * 0.80) The sidewalls on a 195/55 are nominally 107.25mm tall. The 195/65 would be 126.75mm tall, while a 195/70 would be 136.5mm tall.

So the 195/70 is the closest match to the original sidewall height, though it is a touch over. Many 914s can fit 205-width tires, and in that case 205/60 has a 133.25mm nominal sidewall height, which is even closer.

Of course, those numbers are only "rough guidelines", as the measured heights vary between manufacturers and even models of tire.

Lots of choices, though it is getting harder to find really good tires that fit on 15" rims any more.
