Question Changing handling balance: 255/275 vs 255/285

My E90 has the Competition Package so it's 19x9 and 19x10 with 245/35R19 and 265/35R19, respectively. My PS2s are finally at the wear bars and I intend to replace them very soon.

My question is this: what sort of change does a 30mm difference from front-to-rear make versus the stock 20mm? I'm contemplating going either 255/275, or the GTS size of 255/285 which of course makes the rears wider still. I just don't want to upset the balance of the car. I'm aware that a wider front tire will reduce steering feedback/feel.

Daily driver, occasionally autocross or maybe 1 track day. No mods and I intend to keep it that way, nor am I interested in running spacers.


(Also, can a 285 fit in the back of an E90 on the stock 19x10 +25 wheels?)

I'm runninng the 255/285 setup with my daily driver e90 on the stock competition wheels. No issues and look great - just like the GTS.

I have run the 255/285 setup (same wheel sizes except ET22 front and rear) for a couple years now and find it ideal. Have also run stock sizes, 275/295, etc. Preserves great steering feel and sharp turn in, but still very balanced when pushed on the track. You'll never notice +10mm stagger on the street, and even on the track I found it to be very nicely balanced. The E9x does not understeer as much as say the E46 did for comparison, in fact I find it to be fairly neutral to a little tail-happy at times. So the added width on the rears just serves to increase (much needed) traction on corner exit.
