Question about tire rating

[flavionics]

My rear tires are rated@ single 2680lbs or dual 2470 ( branded on sidewall). I assume since the rear axle is dual, the total weight the tires could Carry would be 2470 X 4 or 9880lbs

Anyone?

If you have the 31C, it looks quite similar to my 2001 Itasca Sundancer 31C, which I imagine has similar weight issues to yours. Just by looking at it you can tell it's a very heavy MH with the basement storage and what not. I've never put mine on a scale,actually I've never even driven it. :B It's a higher end kind of C, but unfortunately it comes with a higher weight. 😞

Mich F.. thanks for the link to load rating chart! As I described in my earlier text, I don't feel like I went overboard on cargo and this is a new rig so haven't had time to accumulate much stuff. Although I will take your advise and light up the load as much as possible I think my strategy will be to try and shift the weight forwatd a bit. I have learned a lot already as a member of this forum. Thanks to everyone.

According to figures from your other thread, you had 4,620# on your 4,600# rated front axle. The 65# recommended on your door is for the max. load on your axle. According to Michelin's load rating chart 65# is good for 4,670#, just slightly above your actual weight.
I'd suggest trying 70#, just to give you a few hundred pounds more of a cushion. Going higher than that might affect the ride and handling. I'd also suggest weeding out whatever "stuff" that's not really necessary to get the weight down.

Inside the driver door frame the recommended tire pressure is 65 front 80 rear. If I am operating at Max GAWR in front, should I increase tire pressure to 80 psi for the front tires even though manufacture recommends 65?

That is what the math adds up to........MAX LOAD using MAX PSI

You figure correctly, assuming proper inflation (which for max weight would be the max inflation pressure stamped on the tire, probably 80 psi).

The front tires could carry 2680 X 2 or 5360 lbs, assuming the same tires, for a grand total of 15,240 lbs properly distributed. This is, of course, just the tire limits; axles etc. may well have lower limits specified by the manufacturer.
