Anyways, Porsche recommended tires are 225/40/18 fronts and 265/35/18 rears.
The excessive "stretch" of the tires on the wheels bug me....I suspect the previous owner (young guy) liked the "look" of of the stretched tire.

The Bridgestone S-04 tire ends up being $150 a set cheaper than Michelin Super Sports and I do 100% street driving --- and fairly relaxed driving at that. I'd be tempted to put on another set of Michelin Super Sports but the fact that the rear wheels are 18x10 +55 (whereas OE is +65) make me a little nervous to put on Super Sports in 265/35/18 in the rear because I hear that the S-04s are slightly narrower that Super Sports.
I have a 1996 NB 993 and currently running; Front 225/40-18, Rear 285/30-18, they fit perfectly and no rubbing. A larger tire will give a nice stance and awesome handling.

Hi Mike -- you are running 285/30/18 on a NB in the rears?
Are they still Pzeros? What is the offset of your 18" speedlines in the rear?

Thanks

My previous tires were Pzero's and my new tires are Sumi's and they are both 285's. My rear wheels are 65 offset. No problems with either tires rubbing.

Hi folks ---- thanks to all for your helpful comments and suggestions!
I bought Bridgestone 225/40/18 and 265/35/18 tires and had them mounted on the car. I think I would have preferred Michelin Super Sports but I couldn't pass up the $300 delta @ TireRack between the two.

Mounted the tires on the car and it looks much better --- much more correct and not nearly as strange with the older narrower F-205 and R-255 tires being stretched on the wheels.

BTW --- this is with 18x10 ET+55 wheels in the rear on an M030 suspension on a Narrow Body 993. Since Bridgestone 265/35/18 S04s fit this way, it suggests that 18x10 ET+65 (orig Porsche fitment) with 285 section Bridgestone S04 tires in the rear on an M030 suspension might fit as well...
