Wheel Spacers ???

Hi,
New here and hope to get some solid advice nd information.

I have an old Gulfstream Diesel Pusher which I have had Henderson and safety plus stabilizers fitted. My steering box has been checked and tightened and had 2 alignments. I have Sampson tires on the rear dually and Michelin on the steering axle. My tire shop checked the tires and they are all in spec.
However I still feel wander when driving at any speed over 35 mph. I m assuming it is because the wheels are riding within a semi track which causes the sideways movement because passing vehicles do not give me the same feeling. And yes like all MH's I feel strong winds but then driving a sailing ship fully rigged will do that.
I know there is nothing wrong with the vehicle so heres my questions,

1. Has anyone ever put wheel spacers on a class A (33FT)to widen the track and alleviate the rut problems?

2. I understand the differences between wider and narrower tires and have had conflicting answers. Will a wider tire help to alleviate the rutting?

3. If a spacer is used between the dually wheels, it would still provide the anti rub space and give a wide track?

4. My tire size is 8 75R 19.5 Can I use a wider/bigger tire to achieve my goal of no wander or would I have to also change the wheel and possibly the assembly?

Note, Sampson is a very good tire and used throughout the Trucking world without problems. Yes I know its made in China and have heard all the stories from those who know nothing about the brand and assume because its Chinese made it must be inferior. But for the skeptics did you know that Good Year, Michelin, Bridgestone and many other well known promoted tires are also made in China. And as a matter of fact Sampson are made by A subsidiary of Michelin.
  • I did this to my 87 Southwind on a Chevy P30 chassis. As for the spacers, I do not remember right off the top of my head where they came from. When I get home again I will look in my repair book that I keep for the mh. In it I list parts, places purchased, good mechanics I had found, etc when we are traveling. I will let you know by Friday.

    Thank you Sir, That is the type of info I need, as a follow up what make of Motorhome did you do this to ? And where did you purchase the Spacers from pleas what size were the spacers thanks.
  • I don't know if my experience will help you any, but here goes. I had 8r19.5 tires on my mh and it handled terribly. I went to 245/70r19.5 on all positions and added a spacer to the rear wheels to keep the duals from rubbing together and it changed the handling totally. It steers better, rides better, and handles passing semis and side winds better. From my experience you will benefit from an increased tire width. It did change my speedometer a little, at 55 I am really doing 57. Also, I went with Sailun tires that are made in China, and they are wonderful.
