EC40 posted a topic in General Car DiscussionHello everyone, first time poster. I'll cut to the chase. So I had to refill my rear left tire three times over the last two days. I thought I had a leak in the tire so I used a can of fix a flat to remedy it. I only discovered later (after the tire went COMPLETELY flat) that I just needed to tighten the valve core, as that was where the air was escaping. So my main question is: do I need to replace the tire (that has the fix a flat compound in it) since there are no apparent leaks?
