There is nothing inherently wrong with 18-inch wheels, although I prefer 17s for daily driver/weekend warrior. I am not a fan of the little 15s, although I understand why people do it.
Generally speaking, 18s will handle better on the highway because there is less sidewall squirm. I prefer 17s because they strike a nice mix of sidewall height and wheel size, good for a dual purpose rig.
As for the argument about 18s being heavy and "killing" fuel economy, any larger OD tire can do that and while 18s are a bit heavier, it isn't a huge difference. Usually less than 10-percent when compared to a 15-inch wheel and couple percent difference between a 17 and an 18. Other factors come in to play as well, such as inflation, tread pattern, construction, etc.
To each his own when it comes to wheel and tire package. Very subjective and different answers for different needs.
Also, as stated above, there is some work you'll need to do to fit 35s and the costs only climb from there.
