tire pressure for non stock tires
 

Hey guys, my v4 STi says 2.3bar (33psi) front and 1.9 bar (27.5psi) for stock 205/50/16.

I upgraded to the 04 STi bbs with 215/45/17. Do I still use the manufacturer's psi recommendation for this size?

should be 215/40/17 on a classic so check your spedo reading for inaccuracy

Thanks, yeah its off by 2km/hr, but I wanted to know if you use the manufacturer's tire pressure for new tires.
