When we smash new tyres on, 32 minimum. On something low profile, i always tend to bump up 34-35ish.

4wds need 36 when normal driving.

Don't play with track pressures anymore, but when i used to run the s13 down at collie it'd be 35 front 42 rear. But for everyday be 32.

On my 215/45/17s standard wrx rims i run 34 just push the middles out a bit more for a more evenish wear.
