Yours and the ones in this thread both had/have sidewall separation.
Anyone telling you to run them is one of the "reckless" folk.

I don't know about seeing belts or plies, but one could certainly make an argument about separations in the sidewall.

I found this on a site about CSA truck inspections along with lots of other pictures of acceptable tires.

Tire Inspections | DOT / CSA Insights: Success Ahead

And it clearly shows that the pictures from OP are probably legal, I think that they are carrying things too far. Even going on the premise that it's a dual, and there is another tire to carry the load, with sidwalls like this if one goes the other probably will go at the same time.

Hank, you originally posted that this bus regularly sees long highway trips. I'm just guessing, but around here that means sports. If there is enough money in the budget for any kind of sports venue, there is enough money for tires. Many would argue with me here, but sports is NOT the primary reason for a school to exist.

I think that I would keep an eye on the situation and if the tires get replaced before the next school year, all is well. If not, even at the risk of someone getting into trouble, I think some action should be taken. Isn't someone getting into trouble better than a child getting injured or killed?

Unfortunately if they blow and/or anything happens to the kids it all falls back on you for driving the bus in the first place.

hmmmm....me ranting has brought very helpful info to light.

Anyway,
I spoke to my friend who is in charge of the bus again today. Apparently my rant did something magical I guess because apparently he was approved for new tires.
(actually 3 days ago! Ive been busy and haven't been able to chat with him )

Although him and I count as "several concerned parents" and "a truck mechanic" or as far as accounting is concerned.

I hope I didn't stir too many feathers, im just lazy and have been meaning to post this for a while and I guess I was a bit late.
