I am a new member. I just bought a 2011 discovery in Utah. On the way back to NC I noticed a continuous noise coming from the front tires. After inspecting them, they are both flat spotted on the outside of the tire. Coach only has 18k miles on it. What can cause this and what is the cure? Can the tires be saved at this point?

I think you should also be concerned about the age of your tires.  They may  only have 18,000 miles on them, but they may be older than you think,  You can check the date code on the tires to find out when they were manufactured.  I think there is a rule of thumb that you don't use tires on a motorhome longer than five years regardless of the mileage.
