Two problems related to tire valve have been reported for the 1998 Honda Civic. The most recently reported issues are listed below.
Driving on I-84 during a rainy morning rush hour, at 70mph, my Honda Civic's front left tire experienced an immediate loss of air. I pulled over to the next exit and changed the tire. Took the tire to the local tire shop for repair, and they discovered that the valve stem had failed. At that speed, the tires were ruined, so I had to buy a new tire.

The problem began when the consumer purchased a full set of michelin tires. The common factor of the flats, stemmed from a cracked valve stem, with the crack always located near the base of the stem on the wheel axle side. The valve stems may be too long for the rims.
