i think just use oem tire sizes. 255/30 is probably more than enough grip for the 23i.
Just today i ordered a new set of Michelin PS4S in oem sizes (225/35 and 255/30 19"). Will get them fitted on monday. I have no issues with stock sizes nor do i wish for meatier tyres. If it is enough for a stage 1 360hp-ish 35i then its surely enough for a 204hp 23i, is it not?
Good tyre brand and model probably makes more difference than going up in size. So dont cheap out on tires.

jantes de LDPrestige

LDP - LDM164 - 80x18" 5x120 ET34 72 Poli Anthracite
LDP - LDM164 - 90x18" 5x120 ET40 72 Poli Anthracite

Le choix s'est porté sur ce modèle car je cherchais à moderniser la roue avec une jante bi ton anthracite (salissure moins visible, je l'espère).

Will be installing mild lowering springs when I install new Bilstein struts and shocks in a few weeks.

Wheels were purchased from eBay and tires from TireRack.

Hi! I recently bought a pre owned z4 e89 20i sDrive and I’ve been having a lot of trouble with the wheels and tires.
First of all, the factory fit wheels (17 inch) were removed and were replaced by after market 18 inches by a previous owner. Now the tyre sizes are 225/40 R18 for the front and 265/35 R18 for the rear.
I got the tire pressure signal just a few days after I bought it and had to replace the tires, which again kept loosing air, then got the rims checked and fixed.
I am not losing air now but the tyre pressure warning keeps coming on. Is this something related to the tyre pressure really? Because I pump 36psi to the front and 42psi to the rear. Should I change that? According to the tire sizes I have on now, what tyre pressure should I pump in?
