Tire pressure...Ford vs Firestone

Yahoo Message Number: 20814
Interesting facts given by Les Schwab guy at the Jan. Fort Meyers tire seminar: in the bitter and lengthy legal battles over the Explorer roll-overs...one campany recommended 32psi and the other (don't remember which was Ford or Firestone) recommended 35psi. Problem was the average air pressure carried in the tires of vehicles involved was.....17 psi. Enter the LAWYERS. I think this whole problem came about because the manufactures CHANGED their recommendations...except maybe Goodyear. I'm told trucks always go with the highest pressure because the loads will vary. And which of us looks at our auto or suv recommended pressure...my Grand Cherokee is 33 psi....and decides, oh, I don't carry much...don't have passengers often...think I'll go with 25 psi because it sure rides softer!!! Maybe we have met the enemy....and it is us?!

With all due respect, there is no " enemy" here. There is only a question as to what is reasonable to construe from conflicting instructions. Noone should blindly reduce inflation without some basis---in this case all point weighing. I had my coach weighed while fully loaded with gear for a long trip plus full water and fuel tanks. This weight will not fluctuate enough to call for re-weighing. Plus, I carry in excess of the charted pressures, but not close to the placarded pressures.. There is no reason, in my judgement, to endure an uncomfortable ride quality to satisfy overly protective opinions originating from the legal department. My late father, who was an attorney, is probably spinning in his grave, and my daughter who is now a practicing attorney would probably take exception to my position, but common sense sometimes takes precedence over liability avoidance.
I'm now sorry I even raised this question again and will withhold further comment.

If you'll examine Goodyears and Michelins web sites under recommended tire pressures for a given size. You will find Michelin had to change their tire pressures for the same weight. And both still recommend split weighing your coach. One thing I've observed is from driving newer coaches, that the suspension has been tuned for the highest tire pressures. TWI 11731

Last year when this tire inflation thing was beginning to heat up I sent a number of emails to CC seeking written clarification. I am pasting here the last email I received on this subject. I have yet to see anything in writing, albeit plenty of word of mouth, regarding "must inflate per the placard."
For me I have my coach weighed every 12-18 months and inflate the tires accordingly.

Chuck,

The correct way to inflate the tires is to fully load the coach and have it weighed and then inflate the tires as per the inflation chart, if the coach cannot be weighed then the inflation values on the coach placard need to be used.
Toyo at this time is allowing Country Coach to use its own discretion when setting up tire inflation values. When re-setting the Smart tire the rule is to set the alarm at 10 psi below cold tire inflation pressure for pressure alert (light) and 3 more psi below that for low pressure audible alarm and should be set up this way by weight or by the placard.
Country Coach values our customers saftey above all else.

Thanks,
John.
