245/35/19 front 275/30/19 rears on my xi.

even though xi's are awd they are still RWD biased until they feel slippage (i know this has been said earlier).

xi's still can benefit from staggered wheels but not as much as RWD does.

so just like everyone else has said: 80% aesthetics, 20% functionality.... and nothing looks better than a set of 275's pushed out to the fenders.

There is no advantage of staggered on the E9x other than looks. In fact it just worsens the understeer that car suffers from.

Track fiends would want to run same size tire/rim all around. Helps, but still suffers from understeer.

I'm staggered 265 / 235.

The "why" is simple. More contact patch = more grip. If i could run the 265s on the front, I'd do that too.

As for bragging rights, that doesn't even make sense.

With a little tire pressure management, the xi actually handles nice and neutral. I found it to understeer a bit before I adjusted pressures. Now it's great. On my previous AWD cars, even with tire pressure management, a sway bar was really necessary to get a nice neutral feel. I'm guessing BMWs 50/50 weight distribution has a lot to do with it.

My winter setup, for the record, isn't staggered. I run 225s front and back. Narrower tire in snow = better traction.

Hey man what are you running for pressures?...I have yet to find a happy medium between the front and rear's on mine that I'm satisfied with. (I'm running 235 / 275's) What do you recommend I use? Thanks,

Hey,

I'm running 36R and 32F on my summers. With your larger rear contact patch, you may not get as much benefit. What are your current pressures, and what's your analysis on the feel? Lonely exit ramps are usually the best litmus test for me. I can kick the ass out if I try, but for the most part, she'll just lose grip equally. I don't think you can dial in any meaningful oversteer just by manipulating tire pressure. Maybe without a staggered setup...



Of course, YMMV.

Apparently DINAN agrees with you.
