Cars AI cars won't choose Q tires for qualifying in some tracks

[Apocalypse2112]

It's weird the ai cars I'm using in a championship season are selecting correct qualifying tires for most tracks but they choose soft compound (S) instead of (Q) for Hockenheim and Spa and are about 5 seconds too slow and ruin the season.

Is there a way to force them to use QF tires?

I unpacked the data already. Is there something in tyres.ini that I should adjust for each car?

Are these values meaningful?

[VIRTUALKM]
USE_LOAD=1

[COMPOUND_DEFAULT]
INDEX=3

I actually figured it out. After unpacking the data I found out that the file ai_tyres.ini had these values

[Q]
MAX_KM=17

[SS]
MAX_KM=20

Spa and Hockenheim are longer tracks so the 17 km limit was exceeded (if the cars make 2 QF laps). I just increased the value to 25 and now the ai cars choose Q tires automatically. Problem solved.
