Turbos came with 205/225 tires. I autocrossed one for quite a while that way. Wanna make it more fun? Go with 225's all the way around!

A friend who autocrosses the S2 I used to own just stepped from 225/245 to 245/245.

The factory sets the car up for mild understeer. All new cars come that way, as it is safer for the average (poor) driver if things get out of hand.

The Porsche factory also matches springs, shocks sways, yada yada to the tires. The later cars were designed to go a step wider in the rear, while the early cars came with the same tire all the way around.

On early cars, the standard wheels were 7" Cookie Cutters. The optional Fuchs were 7 & 8, but still had 215/60/15 tires both front and rear.

For average street driving there may not be a big difference in 10 or 20 mm difference, but it sure shows up on the track. And going all the way to 255 in the rear is a gross mis-match if you keep the stock 205 or 215 in front.

Of course, all this assumes a stock suspension. If you want to start swapping suspension components, you can set the car up for neutral handling with 205 front and 275 rears. But that would not make it a fast car. You simply have to reduce traction in the rear so the wide tires do not overpower the skinny fronts.

So, yes, 225 and 245 can be a fun setup on a 944. But that does not prove that wider is always better.
