    I bought a RM 7730  in 2013. It has worked fine after I figured out I had several setting wrong, before that I got errors like: no road, warning-dirt road, etc.

    I phoned tech support and the man walked me through my settings, and explained how to use each one that I was having trouble using.

    The Good Sam version is 7735, same unit with different brand. Both use the same software.

    Perhaps some day I will learn how to navigate. I discovered I had been deselecting things in the forum, when those unwanted emails originated from the basic FMCA preferences for what I choose to receive. I still can't get the unwanted emails to stop, but eventually, with persistence, I may succeed.

    Being a new member has its issues..

    Rayin,  I would be comfortable with suggesting lower than placard inflation IF I am talking with an RV owner that is making an effort to properly care for their tires. Info on placards is based on an assumption that the vehicle owner is not aware or interested in getting a better balance of performance and durability. Those inflations are assuming two things. First that the RV owner will not ever get on a scale and Second will never overload either axle of the RV.

    The problem is that RVSEF, who does 4 corner weights and provides inflation info at FMCA events, that has the data that shows that over half of the RVs on the road probably have at least one tire or axle in overload so the Second assumption about placard numbers is not supported by reality.

    RE tire company suggestions. While there are probably documents suggesting to inflate to placard pressure, I think Brett is correct in the idea that such info is written by the lawyers to protect the RV company when the owner fails to do proper maintenance of the RV tires.

     

    Lets look at what a couple tire companies offer for advice and information.

    Goodyear has an RV specific web site with information on how to weigh an RV and adjust tire pressure

    Michelin provides similar information

    Even Bridgestone tire Co that does not actively market to the RV community offers info on how to weigh and then set inflation

    I read Bridgestones pdf you  provided a link to; under the section "find the RECOMMENDED inflation pressure", the last sentence is: " NEVER use inflation pressures lower than those printed on the vehicle placard."

     

    Now there may be some small importer that has no engineering staff that wants to avoid having to answer technical questions that decided it is easiest to tell people to just follow the placard. This is not wrong but just no optimal advice.

     

    Then there are couple actual tire engineers, like myself, who monitor RV forums and attempt to provide even more detailed info to the small percentage of owners that want the details. But as I said to my knowledge there are only two of us on line and I may be the only one monitoring FMCA forum.

     

    I realize we've discussed this before on irv2.com, but;

    Are you saying we should ignore those admonitions as stated by Bridgestone, Goodyear and Michelin as  "just corporate attorney talk"

    When I joined the FMCA  website I made my choices for what I would receive by email. Seems like every day I continue to receive emails that i had de-selected in "manage your preferences" each of the last 4 weeks. Furthermore when I re-visit the Manage your choices webpage everything is checked again, and I must repeat the process. What's going on?

    UPDATE:  I just turned off everything under "My settings", hope that works.

    Thank you for verifying Brett and all other knowledgeable people on this subject.  I have no idea where all the argumental, new posters all of a sudden came from!  Please don't make a factual statement, unless it is a provable fact.

    We will admit to it, if we are wrong!

    If any of the  cut n paste statements I posted are unproven, I apologize; they came directly from Goodyear and Toyo websites in the links I provided so anyone interested can read the full webpage.

    While I absolutely agree with adding a cushion to the "minimum PSI for a given load", I do take exception to the statement: "No tire mfgr. I'm aware of recommends running less than the federal tire placard in/on the vehicle." You might provide a link to such a statement by a tire manufacturer. Were there such a statement, it would be based on their corporate ATTORNEY, not their engineer!

    The inflation PSI on the GVWR plaque is the correct PSI IF, repeat IF you are running axles at their capacity (GAWR).  Your axles may be well under or over that.  Inflate based on the heavier wheel position on each axle, all tires on an axle to have the same PSI based on that heavier wheel position.

    It doesn't matter if a lawyer or tire engineer made this statement, both are spokesmen of the tire mfgr.

    Goodyear's RV tire inflation loading page states:

    " Tire pressure should never be reduced below the vehicle manufacturer's recommended levels to support load conditions in order to improve the ride quality of a vehicle. The difference in ride quality is not significant. When minimum inflation pressure requirements are not met, tire durability and optimum operation can be affected."

    Toyo tire states:

    " For inflation pressure recommendations for the original equipment (OE) size, refer to the tire information placard (T.I.P.) or owner’s manual. The T.I.P. is commonly found on the vehicle door jam, glove compartment or near the gas cap".

    I have lost the link to Michelin's webpage that stated the same admonition to never run less than the federally-mandated tire information placard.

    I have asked anyone who posts they had experienced a "blowout" how they inflated their tires, by load/inflation charts or federal tire placard, none have so stated.

    It's a proven fact, the more sidewalls flex the faster heat builds up, heat is the #1 enemy of tires.

    You fellas aren't reading the proposed articles and the proposed constitution. They have removed the words "motorhome" and or "motorcoach" and have replaced it with "recreation vehicle". Now with zero definition of what would be constituted as a "recreation vehicle" I can join FMCA with my boat, my motorcycle, my airplane. There is nothing that defines what a recreation vehicle is!

     

    The verbage cannot be changed before the GB votes to accept the changes to the documents, we have to vote them they way they are presented. So, in a campground  get ready for a boat with a goose egg on it parked next to you

    Yup, a Razr is a recreational vehicle.

    I recommend you add 10# to whatever the chart says as a safety margin. Some say 10% but it is easier to just add 10 psi. The tables are the minimum you can run at a given weight.

    Bill

    (thumbs up!) Running the minimum is risky; if the owner checks pressure on a warm day, then begins driving on a cold morning they can be running an underinflated tire.

    No tire mfgr. I'm aware of recommends running less than the federal tire placard in/on the vehicle. Michelin has detailed minimum inflation RV charts that have, in small print, an admonition to never run less than the federal tire placard.

    I went through this in february of this year.  Dates on 1 of the tires installed was 4608 and two were 2113.  I went back the next day and insisted on tires manufactured within the last year.  

    Although the tire dealers say they work with motorhomes all the time, still check behind them.  This same dealer inflated the tires too high PSI for the weight of my coach also.

    FWIW, you'll not find a tire mfgr. that recommends setting air pressure to less than the federally-mandated tire placard in/on the vehicle. Michelin has extensive load/pressure charts, but within the RV chart, in small print, is the statement to never run less than the federal tire placard air pressure.

    I have no idea what the original thread did or did not say but I would vote NO, no towables in FMCA.  Doing so just makes FMCA "another" Good Sam business.

    I completely agree! I joined this year for the unique experience of motor coaches only. I'm already a life member of Good Sam, if FMCA allows all types of RV's in, there is no logic to paying dues to FMCA. This may be my first, and last year in FMCA if they open up to all types.

    We had a reservation for Indy, but had to cancel; DW's surgeon says she is still unable to travel that far, and we live in Bloomington???
