It sounds like an interesting Bedford, I hope it is not one of the many of those series Bedfords running around the Sub-Continent!

BTW: I learn't to drive on a Bedford! An OLB type something similar to the one below but with a non-slewing crane body.

No picture was the stern reply. Only got a square with a little red cross in it. The J's were normal control trucks sold through the 60's and early 70's. Capacities sold went from two tons up to (I think, memory getting hazy) 5 or 6 tons.

Friend decided to build a really good trailer for his race cars and after that built up something decent to pull it. The trailer has three x two ton axles with load sharing suspension he designed with a lot of hints from a Hendrickson springless load sharing design. Trailer suspension is by Aeon rubber springs.

Edit. Picture has now appeared. That is a much earlier model.

Just been on the 'phone with the Bedford owner. It has a GMC 401 Magnum V6, which has been tickled up a bit and uses mostly LPG driving through a Fuller RTO610. As originally built up, it had a 292 Mexico Chev. in-line 6 and 5 speed trans.

He was on a search and rescue mission, as he terms them, in the USA looking for needed bits and went to a truck wrecker on behalf of another fiddler and found this engine. 401 cubic inches (6.6 litres).

The 292 Mexico Chev. is a good trick for a q-ship. I have seen one in an EH. It is the spitting image of a red Holden just a little bigger overall. Painted and decalled, it can pass for a 202 but is just over 5 litres with a bit of a bore job.

Didn't the Australian version of these, particularly the 4X4 have the US/Mexican Chev 292 in-line 6?

Yes, indeed. Some Oz Bedfords were sold with the Mexico Chev. You should be able to find one at a truck wreckers. That one pictured is a KMR with what looks like pommie plates so would most likely have had a Bedford 466 diesel. Oz Bedfords had an eclectic mix of engines over the years. 214 & 300 Bedford petrol, several Bedford diesels, Leyland 400, Mexico Chev, Holden 308, Detroit 6V53. I may have forgotten some.

if 9.00 = 9 inches and 1in = 2.54mm how can 9.00 = 255mm?

While I most usually respect your views and knowledge, on this point you are way off the mark.

Tyre 1 is your 235/85 R16, Tyre 2 is a 255/100 R16 (the Michelin metric size for the double size branded XZL 9.00 16) Tyre Size Calculator @ ExplorOz (although I don't actually trust the sites conversion factors when it reports the 9.00 16 = 230/100 R16)

Results for your selected Wheel/Tyre 1
Rolling Radius 402.95mm
Circumference 2531.81mm
Diameter 805.9mm
Wheel Cover Size Size 009

Results for your selected Wheel/Tyre 2
Rolling Radius 458.2mm
Circumference 2878.96mm
Diameter 916.4mm
Wheel Cover Size Size not available

Differences between Wheel/Tyre 1 & 2
Rolling Radius 55.25mm
Circumference 347.15mm
Diameter 110.5mm

With the difference in diameter of over 4" I would like to see the animal that has hairs of that size!

Ask Michelin, they are the ones who brand their 255/100 R16 as 9.00 16 equivalent!

My thoughts it is because of the different way tyres are measured in imperial and metric standards.

About 10 years ago I changed from the Alliance nato pattern to Michelin XY,s. The fitters hated fitting them on the FC rims because the tyres are slightly larger than 16 inches and they cant centre them properly, so they are a bugger to balance. I get wheel wobble when I get near a 100ks.
Measure a 750 or a 205 and the bead measures 16'. These measure about 16 3/16'.
I wonder if the 255,s are the same.?
The fitter also said that the 255,s are too wide for the FC 6 1/2' rim.
