Default 295/30R19 on narrow body 996?

Does anyone know if the following would fit a narrow body (C2) 996?

“Porsche 911 997 C4 & C4S Carrera S II wheels and winter tyres (full tread / as new). Michelin Pilot Alpin PA4 295/30R19 and 235/35R19 DOTs are 2620 and 2820”

There a good deal on a set on Facebook locally.

Sorry for the follow up newbie question, but what do you mean by "the et of the wheels"?

I wouldn't be lowering mine, so if they fit on your lowered car I'm hopeful about mine!

The et is the distance the outside edge of the rim sits in relation to the wheel flange. The number should be cast into the back of the rim or if they r oem it can be looked up.

U can compare 996 factory sizes with these using on-line calculators.

ET means Einpress Tiefe, which is German for Offset.

Und Eichhörnchen ist Deutsch für “squirrel”. Get some! Wide body ET wheels have more rim behind (after) the hub, so the face of the wheel will be more concealed under the wheel arch and the inner portion may contact body and suspension without proper spacing. A visual is worth 1,000 words. Use a wheel/tire size calculator to see what those tire and wheel numbers look like.

I am running 295/30/19 tires on 19x11 wheels and 58 offset on lowered C2 , I wouldn't run any less than that for rear offset.

That is not entirely correct as where the outside edge sits is also dependent on the wheel width.

ET is defined as the distance between wheel flange and wheel centerline.
As such one needs to know both ET and wheel width in order to calculate where the outside and inside wheel lip are.
