Greetings, I have a 2006 Police Roadking FLHPI. I only have 3500 miles on it and wanted to swith out the tires. I currently have the Police Dunlop tires on it, which came stock from the factory. I have been told that I shouldn't ride 2 up with these tires, but I have never had an issue with the 3 Police RK's that I have owned in the past. What would be a good tire to switch to and whatis the widestrear tire that I could put on, as everything is stock? Thank you.
