hi guys, thought i would jump in on this thread. i just put on bigger tires on my 2010 RX. Pirelli scorpion all terrain plus 265/60r18 on stock rims, black plastidip. Stock size was 235/60r18. Feels more like a truck. I didn't take a before measurement but i think i gained almost an inch just with tires. Slight rubbing when steering wheel is turned right all the way going slow and hitting bumps. I have 5mm wheel spacers ordered. I'm going to try that.
