There are a few threads on this topic that go into the issues in greater detail...I do not have any personal experiences w/4WD 993s (both of mine are 2WD) and so am OK w/running "weird looking" combos (

225/40 = 25.08 Diameter
78.79 Circum.
285/30 = 24.73 Diam
77.69 Circ
285/35 = 25.85 Diam
81.21 Circum
Stock set up = 1.4% Diam; 1.4% Circ
My set up = 2.98% Diam; 3.1% Circ
OK or no? The fr/rr correlation swings from larger front to larger rear BUT the differential spec stays in check/tolerance.
Thx

Folks, Answering my own question here... for those who have Wide Body AWD and cares...
The 295/30-18 & 225/40-18 is even a better combo that the original stock one (285/30-18 & 225/40-18) Just spoke with Damon @Tirerack and he confirms. Bought my 4 new tires...

I had a set of the Pilot Sport Rib on my 993 and liked them very much. Much better than the Bridgestones I have tried in the past (S03 and S02)

I like the look of the 17" as well, but it was time for a change. Now that the 18" are on I really like the look with the lower stance. I also think the Turbo body can handle the 18" wheels without them overpowering the look of the car and they were an option for the C2S when new.

Perelli P Zero's all the way! Went thru four sets in 35k in the rear and three in the front. Can't beat them when they get heated. Soft but predictable. Cheap tires are great beacuse they are cheap but the P-Zeros are hard to beat. The new ones I drove on the Audi R8 took a beating and had low wear. Nice and sticky and with 4-wheel drive never gave up. Perelli had two trucks there swaping out tires once they got worn. Unless you do a ton of non-agressive driving, try the others: otherwise stick with the P-Zeros.
