I own a Honda 2008 Air Bag Gold wing converted to a trike. I keep losing air in the front tire. The OEM tire has been replaced with Mich. Pro Activ mounted in reverse direction on the front. Tire has been remounted 3x and rim wire brushed. Still losing air. Option is to place a tube or what. Loses 5 lbs every 3 to 4 days. Suggestions to prevent or cure my problem are appreciated. Is it safe to ride with a tube?
