I am a Desert dweller myself live in Tucson Arizona. We have been on a road trip for over month now. Bought it in late October with 5K miles had about 6500 when we left In December and clocking in close to 12K now. Stock tires and wheels (1958) for the couple of weeks I had with the stock wheels I got 20-21 and a best of 23 on a round trip from Tucson to Phoenix.
Really do like the KO3s they ride great, excellent in snow, ice, rain and off road. Slightly noisy vs a stock tire but not bad at all. Absolutely no balance issues and wear is excellent.
