half way grown:

20's are pretty much out of the question, and a lot of it depends on road's in your area as well....if you have a lot of potholes or shitty roads, i would go with something no bigger than 18's, and 18's do look mint on 5th gens. I'm just tellin you this because we got some bad roads out here and my friend has a 5th gen with 19's and he cracked one the other day, he is always sayin he wishes he got 18's so he didn't have to deal with it.
