I posted this reply over on the MAK board as well:
I too think that these are great videos. I have written to Michelin to get permission to use them in a new safety-related DVD I am producing. This DVD will be made available for free to all RV folks.
Bendix also has some great videos and I have written to them for permission as well. Getting permission to use these videos is not a lot of fun, since you end up dealing with their lawyers.
The DVD will also include my two safety-related articles in a narrated slide show presentation.
Lots of work, but I think it will be of value to the RV owner.
If anyone has any other videos that they think should be included, let me know.

That brings up a question for me. How many PSI should I be running at on my 4905?

Kevin, the ideal answer is to have your bus weighed on each axle and each side, then go to your tire manufacturer and find out what pressure will give you the correct load capability for that particular tire on that particular location. That is the thesis of one of the videos posted above.
Next best would be to have each axle weighed (total) and assume that they are about the same load side to side. Any truck stop can do that for you for a nominal fee.
Next best is to go to the GM bus yahoo group and see if someone with a bus like yours has done that work. Here you risk variations from one bus to another, but you would be in the ball park.
Lastly, you could hope that your bus has the correct size and rated tire and simply inflate the tire to the max pressure. Then, with a thin piece of metal, see if the edges are touching the ground (i.e. the center of the tire is now bulged out). This method is, at best, a ball park approach.
Bottom line, each bus will have slightly different pressures depending on the weight on each tire location, the manufacturer of the tire, the tire rating (plies) and the tire size.
