The reason you can get away with 10's on the back is that Beddies can have dual wheels, add the two rims plus the gap plus the allowable difference and technically you can go bigger than 10's

14x8 and 15x8 have different offset, try 14x8's

when I got my 15x10's from USA I also got 15x8.5's but the offset of the 8's had the same effect as your having now.
I don't believe you can get a different offset in the 15x8's

If you are ordering new wheels you can order them in any width/offset unless they have a restrictive sales range

Hey Benny, i am going with a set of 15x8s all round, am i ok with those, or will i have a problem.

Hey aaron, mate back in the early 90s when we did my van the first time, we rubbed the body down by hand, looked good, when i started sandblasting last year, we found all sorts of uglies, this is just my opinion, nothing beats sandblasting / sodablasting. In just a few hrs you have no secrets, all is exposed. Good luck.

Ok done a stack more research and found out the following: Note these are just inferences i have made from looking at a tonne of info from the net so please do not take them as fact

The standard beddy wheels were a 5.5J 14 which basically means 14x5.5's with a 1.5" posative offset (38mm)
Now for a light goods/commercial vehicle you can increase the track up to 50mm, not 25mm as in the case of a passenger vehicle.
So here's the gotcha: increasing the track 25mm a side (Total 50mm) would give you a wheel with a 13mm negative offset or approx 1/2" regardless of wheel size and width

So any mags with a 0mm offset or any negative offset cannot be used
ie 15x8 with 4.5" backspace, (0 offset as 8"wide mags are actually 9"wide from face to face) illegal
15x7 with 4" backspace (0 offset) illegal
15x8.5, my current fronts with 3 3/8" backspace (32mm negative offset) illegal
15x10, my current backs with 3 3/8 backspace (49mm negative offset) illegal

Now i know because the beddys had dual rears, you can run 15x10's but to keep the track the same you would need to keep the standard diff and have a backspace of about 6.8" insane
And finally, having a much narrower holden diff and the 15x10's i'm currently using means yes my rear track is within acceptable limits but  "If a solid axle from another manufacturer is used, the wheel track may be increased by 50mm beyond the maximum specified by the vehicle manufacturer for that particular axle" so again its a fail

As far as my understanding goes, because of the shit choice of wheels used by Bedford any mags will increase the track by >50mm and therefore not comply without an engineers ticket, by the way anyone know what they cost?

Rant over

PS for some reason i cannot upload photos but this link shows positive negative offset. I actually thought they were the opposite way around but either way my point is still valid

I tried attaching your picture to a post but got a "folder is full" message, so I uploaded it to my album and inserted the link in this post.

Now i know because the beddys had dual rears, you can run 15x10's

where has this info come from?

"If replacement single wheels are fitted to a goods vehicle originally fitted with dual
wheels, then the tyre width must not be less than the sum of the widths of the original
two tyres fitted on the dual rims"

[ben]

nice to know cheers

Ok had a phone call returned form the engineer today which kinda ruined everything, short story is i'm still gonna do it, it's just illegal
You cannot increase the track width without replacing the axle from another vehicle, which is deemed strong enough to support the new wheel, tyre, track combination
Even then it requires engineers cert. In the short, deep dish mags are VERY hard to get certified, at least on a Beddy anyway.

So my method now, is as long as it looks kinda legal, just hope like hell no-one asks any questions
