here's my wheel/tire situation for my 2012 IS350 AWD

rear setup: 18x9.5 +22 with 275/35s
front setup: 18x9.5 +40s with ???

which tire size (rolling diameter < 1%) should I go for to prevent rubbing and heavy steering? Thanks!

try 245/35-18.

try 255/35/18 front and rear. or 225/40/18 if you want the stretched look

Thanks guys but I'm trying to keep the 'rolling diameters' close to pair up with my rear 275/35 tires. So the above tire choices seem to be my only options as per 1010tires calculator. I am only going for a small F-Sport drop.

then, of the ones you listed id go for 235/40
