I have just experienced this situation.
Original tires on the ES350 were Toyo Proxes and began to give road noise at 27000. Still some tread remaining but decided to put on new tires anyway. I desired a slightly wider tread so went for 225 (the OE was 215). My error, the shop put on 225/50-17. They just didn't look good --- dinky tire and too much wheel well. The shop agreed to change to a 225/55-17 and it is PERFECT. Ended up with Yokohoma YK520 and couldn't be more pleased. Extremely quiet, very comfortable, true tracking and they look good. This was one of my better purchase decisions.
