I was running the Formula GT Championship in B Spec. I suspended the series after Monza, so when I started it back up today I was at Suzuka. I went into the car settings to change my gear ratios, and after I was through, I tried to back out to the race menu, but was told "Regulations Breached." That's when I noticed that my tires were set on Sport: Super Soft and had the little red "no" icon beside them. It wouldn't let me leave the screen until I changed the tires, which I did, to Racing: Softs.
So I start the race. I start looking at my opponents' stats. Every other car is running Sport: Super Softs. As the race went along, I would look at the opponents' stats periodically. I noticed that their tires weren't wearing down at all. They did have to pit around laps 27 & 28, but only for fuel.
The car I was using was (of course) the Formula Gran Turismo and my bob was level 27. The AI ran Racing: Hard tires for every other race except Monza, which they ran Racing: Rain tires due to 100% track wetness.
I just thought this was something interesting to share with everyone. It appears (in this thread, anyway) that the last time anyone talked about this was about 5 months ago. Has anyone else had it happen to them lately? I saved the replay, and if I knew how to, I would show it.
