Left front tire low air pressure. Went to get problem corrected. Repair technician reported the air was leaking around the valve stem. Technician dismounted the tire from the rim and discovered that the chrome plating on the rim was flaking off and had a gap between the rim and the valve stem allowing air to leak from the tire. Options were to either re-chrome the rim or purchase replacement rim. Also, tire needed replacement due to being run underinflated. Result: Purchased 4 new rims (not chrome plated) and a new tire. Total cost $ 700+.
