Tires for 200x smaller sizes?

[Trimoto Mike]

I've read just about all of the old posts on tire sizes and it seems that most people prefer the the 20 inch or 18 inch rears. But different opinions -- I ride mostly flats. I would your opinions on the following sizes:

Front tire: worth going to a 20 inch front? 20x7x11

Rears: Either 20x11x8 or 18x11x8

I really like the lower height - it feels more stable and the front end being lower seems like a plus.

Thanks!

If you mostly ride it on the dirt roads around Deer Trail, you'll lose top speed by going to smaller rear tires. You could change your gearing (sprockets) to get that speed back.
