I buy mine from HDL, the site sponsor - they ship quick & have the price guarantee.
As far as mounting, I take my wheels off and take them to Gulf Shores Power Sports on Hwy 59. The price is starting to go up and this last go cost me $ 42 ttl. I would think the Honda shop near Fairfield Ave would do it for you.
Ft. Walton Honda Yamaha just mounted a set for me. Price was just a few bucks more than the internet price for tires alone. Give them a call the prices are unblievable. You do have to order the tires ahead if you want Avons or Metz.
