simplicity suspension on supreme territory

Sparky21,
There may be absolutely nothing wrong with your suspension setup, but it's worth getting it checked.

The fact that all roads have some camber can cause the wear pattern you have experienced.

My old Viscount GrandTourer (80's) was showing similar nearside wear, I suspected a bent axle, the van has solid axle and leaf springs.
I stripped the whole axle assembly down to just the axle and removed it for checking on a longbed lathe. No run out so axle was still straight and true.
Next I replaced everthing and checked the axle assembly alignment on the 'van for misalignment fore and aft. Still OK
Finally I checked using a plumb bob on a flat concrete floof for bent chassis and drawbar. Everything was Ok.
Then I spoke to a couple of Tyre dealers. Both of them independently said that road camber can and often does cause the symptoms I had, nothing you can do about it.
I've learned to live with it and replace the tyres when the wear is approaching the unsafe stage.

Hope this helps.

Yes, couldn't agree more with Disco Driver. I have a Coromal Poptop, with independent suspension, and the tyre wear is very much on the outer shoulder of the near side wheel. I rotate the wheels, of course, and also have the tyres turned on the rims to even out the shoulder wear.
I thought it was about the Coromal design, but now I am beginning to think it is more common.

I had that problem on my Phoenix (with Alko suspension) it turns out that I was not putting ENOUGH weight in it, I bought it second hand and the original owner carted a lot more stuff than we do.
I had the suspension rerubbered and that stopped the problem, I am not sure about the Simplicity but you may be able to get it reset.

I have a 2003 Roadstar Voyager 4000 with Simplicity suspension and do not have this problem at all.
All my tyres are wearing even and no scrubbing or outside wear on them.

Have you been parking by touch and knocked them out of alignement.

Best ask Simplicity for an answer I would think or Supreme.
Cheers.

If the van has tandem axles, wearing the kerb-side tyre shoulders is probably quite normal.

Left-hand bends are the tightest turn for the kerb-side tyres. Because the wheels can't steer into a turn, they have to scrub their way around and it seems logical that the outside shoulders will cop a bit of a hiding every time. Right-hand turns are far less stressful on all tyres, simply because the turn is always a wider one.

Stand on the corner when a tandem van is turning and the scrubbing is pretty obvious. Combine that with a bit of extra weight from road camber and it seems to me that wear on the kerb-side shoulders is to be expected.

When it became evident on our tandem van I removed the tyres, turned them over on the wheels and swapped sides. They all ended up turning in the original direction but the worn shoulders are now on the inside of the off-side wheels.

I am currently building a off road tandem van with a 4.5 tonne Simplicity Suspension and have been told by many people that the suspension can sometimes need alignment.
The Simplicity suspension has the ability to be aligned similar to your vehicle.
I did an alignment check when I fitted the suspension to the chassis it was correct.
Contact the manufacture of Simplicity, N P Hauffe & Co Victoria and they will be able to set you straight. They are very good people.
