I had a problem with the spare tire of my car that was loosing pressure to the point where it was fully empty. I alway bring my car to the city Toyota dealer for service and they never were able to find the problem. Then I I brought the tire to other shop. There they told that the tire had a ruptured on the side of the rim. I came here to South City Costco tire center to buy a new tire but I explain to Julio the situation and he fix the tire. The tire was loosing air because it had and old patch where the air came out and the valve was loosing pressure. So Julio sealed the old patch and change the valve. Now the tire is fine and the light doesn't come off on the dashboard. Great job Julio. Excellent job!
