I am considering the following set of Porsche wheel and tire but not sure if they fit my 91 S4. Really would like some advices. Cheers.

Front:
18X9j et40
225.40.18

Rear
18X11j et51 tires
285.30.18

Definitely not on the fronts, that offset is waaay to low. I'd personally never go below a et50...Most say not to go below et55

If your gonna go 11'' wide on the rear be prepared to roll the fender lip a bit.

I personally do run 11'' rears and have had 295-30/18's on the car but I now run a 285 series tire and find it to be a better fit. My fenders are rolled slightly.

Thanks for the advice. I guess that i am still keep looking....like to move to 18 inches from my 17 inches cup 1.

The Forgotten On

My self and a few others use Panamera rims. They are cheap, plentiful, and are high quality OEM.

The fronts are et59 as well, much closer to stock.
