If you live in MD and the roads are bad as they are here in New England, 24" wheels are not a great idea. IMHO, anyone that says they are getting better ride quality using bigger wheels, probably doesn't have enough air in his tires. Just like bicycles, it's the amount of air pressure in your tires and the amount of rubber that protect your rims.
Now, if you live in the south where roads are much better, 24s are not an issue.
Your choice...slave to fashion or......
