Just to share my experience, approx 12-14 yrs ago I had a right front tire blow out.
Previously, I had read the Greyhound drivers hand book which said that you could, in
an emergency, apply the park brake and maintain control. In my case, when the tire
let loose, I remembered what I had read and did just that. It took a long 1-2 seconds
to realized what had happened and I set the park brake. The bus shook and vibrated
a lot, but control was not a problem. The bus slowed to a stop on the shoulder of the
road. Between then and now, I keep a close eye on the DOT codes so tires don't get
Also I recently changed to 315 75x22.5 tires. I know it is more tire than I need, but
It gives me warm fuzzy feeling about tires. I noticed that most new coaches run this
size, so must be a good reason for it. (probably the potential for 47 law suits)
Hopes this helps, Merle.
