Hi everyone!! I have an 08 ES350 and recently I've been looking for a set of 18" rims+tires to replace my OEM 17"s. I found a set I like which is 18x7x5 with 45 offset. Will they fit? What are the pros and cons with 18x7 and 18x8? Also, what tire size should I be looking for if I want to keep the ride comfy like stock and hopefully with the same or even smaller gap? I'm not planning to lower my car but I don't want my car to look like a 4x4 lol... Thanks in advanced and happy 2014!
