I think most builders have at least one slow leak tire on their aircraft. On mine its the nose gear tire, it leaks down over a couple weeks while the mains have never leaked. I was thinking about putting tubes in the tires, but that adds extra cost and weight (I assume that is why tubes are not included in the kit?). A fellow builder Bob Stuart (CH701 plans only) suggested removing the valve stem and injecting (syringe) 5 - 10 cc of anti-freeze then installing the stem and inflating the leaky tire. The anti-freeze helps to seal the low pressure tire / rim. Bob claims its a trick used around the farm for years. I will give this a try on the nose tire before I install a tube.
