    I know I'm being a pain and I apologize... just want to get this correct and be sure I have this straight in my thick head....

     

    Factoring in a 15% cushion, and the additional weight of full water and fuel, I THINK I'm looking at 3500 LB on the front tires, and 3700 LB on the rears.

    according to the load inflation chart, thats 80PSI on the front and 85-90 PSI on the rear.... ?

    Just an update... I went to a Loves that had a CAT scale, and was able to get a weight on each axel, although, not 4 corners...

    Weight is fully loaded with 4 adults and all our stuff....

    Steer Axel = 5740

    Drive Axel = 12320

    Gross 18060

    So I'm good if I'm reading charts correctly... I'm at 95 PSI... probably drop them down to 90 to give me a margin....

    How does it handle with that much PSI in the tires? FYI, most tire shops have an SOP to fill tires to their MAX PSI rating, they do not want to be responsible for underinflated tires nor do they know what your vehicle weight is. 

    It rides like I'm driving on rocks, expecially if I hit a rough patch or a bump.... no 'give' in the ride at all

    The spec sheet shows 120PSI and that is what the tire shop I got these installed from set them at.   I got confused when I saw the placard on the coach talk about 80PSI

    The Tires show max 120PSI cold weight on the sidewall

     

    ps.. I much appreicated your help :)

    Welcome to the FMCA Forum! Glad to have you join us.

    When you say:

    ...are you talking about what's on the sidewall of the tires as the 'max cold inflation' for the tires?

    If so, then that would be the amount of air necessary to carry the max load the tire is rated for, not necessarily the pressure that should be in your tires.

    The best way to determine the proper tire pressure is by knowing your coach's actual weight (by axle) as you typically roll down the road, and then using the manufacturer's load & inflation charts to select the correct pressure.

    If you post the brand & model tires you got someone will surely help you find the load & inflation chart.

    Sorry.. this is all greek to me....

    The Tires are 245 70R 19.5 load range H

    I have Double Coin RT600 Steer tires on the front.   The link to the spec sheet is:

    https://www.doublecointires.com/tire/rt600/

    On the rear I have model  RLB 490.   The link to their spec sheet is:

    https://www.doublecointires.com/tire/rlb490/

     

    The Fleetwood Flair spec sheet shows the GAWR for the front at 7000 and Rear at 13500

    GVWR 20.500 and GCWR 24,000

    hopefully this will help me get information.... I'm confused about being able to take the tire down to 80PSI from 120PSI, mainly because I do not understand :(

    May have been discussed, but I'm confused a bit.....

    My coach tag says my front and rear tires should be 80 PSI for the weight of the unit...

    The manufacturer of the  tires I had put on says the tires should be 120 PSI..

    They are 245 70R 19.5 on a 1999 Fleetwood Flair 34D
