I suggest, do it right. An axle weight scale cost $10 at a truck stop.
FYI 90 lbs in a 22.5 tire with this light weight coach is NOT low tire pressure

Agreed. Just some posters are saying to keep trying lower pressures until the rig handles better on the road. I'm saying that is no way to set your tire pressure.
My rig is 105 lb up front so 90 lb is very low for me. Just saying

X2. I also don't know what the "recommended range" being discussed refers to unless it's the range between what the inflation tables call for and the maximum PSI for the tire/wheel combination.

As a newbie with a new 40DP, I had the same concerns about the handling of my coach. After giving the dealer, a Freightliner Oasis shop, and an alignment specialty shop multiple cracks at fixing it... I took it to Henderson's Line Up in Oregon where they added a steering stabilizer and motion control units. When I drove it in, it was a white knuckle ride. When I drove it out I was relaxed with only two fingers on the wheel.

BUT, all of the things mentioned so far need to be checked first before putting a band aid on a problem.

Best of luck.

Rick

Hi Rick

We agree again. My rig wandered all over the place. It had a out of balance vibration.
I took it to Josam in Orlando.
My new Goodyear tire was out of round. They shaved it. Alignment was off. And they reset the height. Now drives like a charm with my same tire pressure.
I guess that's what I'm trying to say. Make sure everything else is good first, by a good shop. Usually makes a big difference.
Rick

i had my experience on this topic... if tires and alignment are all good, first check hydraulic fluid level, in some rv's it's being used for both hydro and power steering. more than likely that is the cause. else, look into power steering valves - o-rings could be cracked making the fluid leaking to opposite direction while driving (search in Country Coach forum for this - a guy did very thorough documentation in his searching for a solution on the same symptom).

a word of caution about your tire pressures. They will rise when on the road so checking them cold then letting 5lbs out when they are hot... may not put you where you want.
Corner weights will be hard to get unless you have someone local that specializes in it. Although there are lots of DOT scales that can weigh each axle to get you in the ball park. And when you get your axle weights... try to have the fuel tank full, propane full, water tank full, and any other standard equipment you have on board.

I read on here that Michelin tires are the #1 cause!
Or maybe it was "off shore made tires"??
Or maybe it was 7yr +1 day old tires...

We have digressed so I guess it is time to unsubscribe from this thread and spend some time elsewhere on iRV2...

Happy RVing to all and I hope you get your tire inflation issues resolved.
