Just realize you need some clearance for things your tires might bring up with then. Sometimes the road here after a rain will have a really sticky gumbo mud washed out over them in patches. That stuff clings to your tires and you will be brought to a halt from it being jammed between tire and frame. If you have enough clearance, you can just let it sling itself off. Without, you'll have to get more dirty as you carry your bike to wherever you can find a hose to spray it off.
