what tire size

So have my wheels auto couture 19x8.5 front and 19x10 rear they will be going on a 3gs what tire size should I go with 245/30/19 265/30/19 or 215/35/19 245/35/19 tell me what you guys think

It depends on your clearance issues, there's no standard.  I run 215/30/19 on 19x9 and 235/30/19 on 19x10.  But it really varies from car to car.  Don't stretch just to stretch...
