Fox tyre pressures in garage can be set up max to: 188 kPa in front and 165 kPa in rear :
But when you leave garage you can change rear pressures in F12 up to 188 kPa:


Another thing could it be changed that pressure could be changed in F12 by 1 not by 5 at time?

Edit: found another bug.
Minimum pressure for Fox in garage:


Minimum pressure i could set out of garage(cant go lower):


Edit 2: so pretty much most of cars that has bigger or lower front pressures it takes same pressures as limits to rear tyres.

The first bug is not exploitable though, because if you put rear tyre pressures over 165 kPa in F12 menu and make a pit stop, the pressures will still change only to 165 kPa.

But every consequent pitstop will result in LFS trying to do a setup change, although you didnt change anything. As its trying to do a 188, any you have 165.

And because it moves by 5, you cant get back to 165. If you go back to for instance 163 (doable from 188), and pitstop then, after that pitstop it will still show setup changes requested, and do a setup change on next pitstop. IT will change nothing, but it will do a setup change.

So basically, the problem is that LFS in F12 menu, takes front tyre values for rear tyre changes. Your scope for rears is same as scope for fronts.

Checked yesterday, this has not been resolved yet.

It would need a patch.
