275/35ZR18 on 18x9.5's all 4 corners. The handling and ride are awesome, but the speedo is 4mph off on the highway. 81mph on speedo=77mph on radar. You could program it to be right, but I'm too lazy!!

25.6" . . .

That's my thinking too. GM says 25.7" and the GS-D3's run small at 25.5". The new set has been verified by laser and radar as 5% off at 35mph, 80mph, and 140mph.

I wonder if a previous owner had drag radials or something on this? I often find strange things on this car. I guess I'll just have to measure the circumference and have it programmed to what it should be. I bought this size so I wouldn't have to adjust the ABS, which seems to be OK.
