So I went up one aspect ratio F&B

I just installed some Nitto Motivo tires on my 330i sport.
Went to a 255 40 18 in the back and 225 45 18 in the front.

Comfort is better (expected) but it feels a little squirmy (ok, maybe a little expected) in the corners compared to the 255/35-225/40 from the factory.

I'm running 33psi front and 36psi rear.

Since I'm running .5 in taller sidewalls now (tires are 1" bigger diameter vs stock) AND I'm not running RFT should I take up the psi to closer to 36/40?

I'm thinking non-rft would need more pressure, and taller sidewalls might benefit from a few more lbs as well.

What doe you guys think?
