My RVSEF safety booklet says that my weight distribution can vary widely depending on the air bag inflation while on the scales. It recommends to NOT dump the air while on the scales. Any comments on this?
What is the maximum allowable weight difference left side to ride side? My left front is 600 lbs. more than right. Is this normal? 99 Intrigue

Regarding tire pressure and coach weights.
I just returned from a lengthy visit at Les Schwab in JC and learned that both Toyo and Country Coach are recommending tire pressures be set to the recommended max pressures written on the coach mounted placard and NOT according to weight. I have this info from several well creditionaled people at CC and Les Schwab.
Comments from the group??

Tom:
With all that has been said on this subject, I am curious why they would recommend to maintain the tires at maximum air pressure. This seems to be a bit overkill at the expense of ride comfort, etc. Was there any explanation given?
My coach was delivered with 90 front, 95, rear duals, and 100 tags. This was verified as the correct pressure for the weight by RVSEF, Les Schwab at JC, Toyo, and of course CC whom also had set the smart tire for those pressures. Notwithstanding of the foregoing, the placard next to the driver has 110, 120, 110 psi.
I do not disagree that erring on the conservative side is a good rule of thumb, however, it can be taken to extremes.

But there might be a danger that the pressures on the coach placard are less than what's required to support the weight that's on those tires!!
That said, inflation to the max pressure on the *tires* may be a good idea as long as you consider that over-inflation: (1) reduces traction (increasing emergency stopping distance, etc); (2) increases wear in the center of the tread; (3) makes the tires more susceptible to impact damage (pot holes, etc); (4) increases the shock to drive train and suspension (excess wear) and coach components (squeaks/rattles); and, (5) decreases ride comfort (which may be personally acceptable ... or not).
Conversely, over-inflation gives a safety margin before inflation pressure drops to a point inadequate to safely support the weight that's on them.
In fact, we inflate our coach's tires 5psi above tire load/inflation table specs as a safety margin. Everything's a compromise after all .

To all who responded:
I asked whether this "new recommendation" was simply for liability reasons or was it really best to follow the printed placard.
I was assured in each instance that the printed recommended pressure was the safest and therefore best pressure to us and sacrificing safety for comfort (lower pressure/softer ride) was no longer what should be considered.

Hi Folks,
Now that CCI has reported 500 new employees and double in sales - their liability insurance has gone up I suspect. Who is driving these statements? What is the hidden agenda. It flys in the face of many of our group's threads over that last 3+ years and the Toyo charts. I mostly don't believe the recent statements. On 40 footers with no tag wheel, I would probably believe it.

If in fact CC and TOYO have changed their official stance relating to acceptable tire pressure they both have a duty and responsibility to transmit this information directly to all customers, original owners and second hand owners.
To avoid liability CC may be advising the higher pressures on new deliveries regardless of the ride quality. IMHO Once the coach has been officially accepted by the dealer/customer the responsibility transfers away from CC.
If this is the case, what is the position of TOYO who has placed in the hands of many users a chart showing recommended tire pressures based on weight and those readings are typically lower then the CC coach plate.
I run 110/105 which is lower then the 120 listed but a lot higher then the figures shown on the TOYO chart for the weight I carry. I have run with 120 on the front but found the quality of ride deteriorated, especially when the fuel tank reached close to empty and the weight on the front axle was reduced.
Not sure I want to return to 120 but would consider it if TOYO changes their position.
