Default Lowered split - really uneven tyre wear, can anything be done?

Turning my attention to ride and handling now, and would love to know if what you see below is what I can expect from a lowered bus, or if I've got some geometry wildly out!

The bus is a Brazilian K&L beam running 175/65 R14s on stock steels. Splindles have been flipped, everything else is stock. The tyres shown are just crappy car tyres fitted when I bought the bus, and they've worn a good 5mm more on the inside shoulder than the outside.

I have some new van-rated tyres fitted up onto a straighter set of rims, but have held off fitting them as I don't want to scrub them too badly.

I rebuilt the beam 12 months ago and didn't try overly hard in the set up - I shimmed the link pins as best I could (but found it difficult to get an accurate measurement of the top-to-bottom trailing arm gap) and I set about 5mm toe in measured at the rim.

Any suggestions??

My ex bosses lowered barndoor van had problem with scrubbing out tyres.I tried aligning it with old school dunlop guages but the bumper got in the way of the mirrors so I set it up using some gunson trakrite plates and it seemed to cure the problem.Never used them on anything else though.

So, thinking tracking rather than camber ?

I would get it properly aligned camber will effect toe (tracking) camber is adjusted with shims. There is a base setting in a decent workshop manual i.e. Bentley. Adjust the camber first the set the tracking.

5mm toe in sounds a bit excessive to me (not checked the book admittedly)

Also, if the rims you tracked it with are a bit wonky, the position you fitted the gauges at the time might be out.

Fit a set of straight rims, then get it professionally tracked.

I have the settings, but had issues when shimming the link pins trying to get accurate measurements from the ends of the trailing arms

Anyone used one of these camber gauges?

I've used a three way gauge which clamped to the wheel rim and gave castor, camber and KPI levels. I found the bug's camber on my n/s was way out, adjuster turned the top in towards negative and all is good.

Where are you based as Cris at Birks motor Engineers, Chinnor, nr High Wycombe can sort you out.

Nowhere near unfortunately....at the top end of Worcestershire. I've yet to find anyone nearby who doesn't expect to work from the specs on their laser tracking system....which oddly enough don't go back to 1975 vehicles!
