FLAT TRACTOR DRIVE TIRE

It's remarkable that I've had so few flat tires during the past 187,000 miles. Approximately seven months ago I got a nail in a steer tire and had to replace it. Then yesterday, I discovered an air leak in one of my drive tires. The tire tech at a truck stop in Oklahoma City discovered a nail embedded in it. It took longer than anticipated to get back on the road.

  Within about three months, I'll probably need to consider buying a new set of tires. They are getting noticeably used.
