Biggest wheels?

The only reason for welding the studs is because the drilled a clearance hole and not a press fit hole when doing the conversion - WRONG.

So as you and others have said - go for the PCD size that you have the most options with.

As for the BMW or Range Rover wheels not being strong enough - well the RR is a 4WD so the rims should be heaps stong enough, and the Beddies arnt that heavy.

If you find a good engineering firm near you, you might even be able to get them to do a disc brake conversion, say using suitable BMW disc's and callipers and drill the rear at the same time.

Any engineering place that is involved in motor racing or hot rods would be were I would start looking.

Find the right people and the rest will fall into place.

i spent 60 bucks on drill bits redrilling an axel once to get the right size.. bit tricky to judge what size is perfect lol..

The right tool for the Job

The important thing is to have accurate messuring tools ie vernier calipers or micrometers for sizing drills studs etc.

Correctly sharpened drills - drills can drill oversized if not sharpend correctly.

Use a pilot drill/hole.

If at all possible it would be better to have the holes machined out using a correctly sized end/slot milling bit - they have more cutting flutes than a drill and tend to be more accurate.

If there is no profile number on a tyre, then it is full size. "80". Which means that the height of the sidewall is 80% of the width.

So, by using the tire size calculator I get these values:
195/80-14 has a circm. of 82.6" and the closest match in a 18" rim is and a 235/45-18 with a circm. of  82.7"

If this is correct the odometer won't be off by too much, thats one thing they will check when legalizing different size tires.

Now the harder part is calculating the correct offset and finding a corresponding rim that wont stick out of the fenders.

Update!

Ok, I know I said I was going to re-drill the hubs but a set of adapters appeared on ebay... and I bought them. They weren't cheap but I can always sell them if it doesn't work out.

From what I have gathered the company here that legalizes new tire sizes won't pass cars that have spacers... well I guess that adapters are the same... but they don't remove the wheels so if they don't see it it's like it's not there... 
So it depends on the rim... if I can get standard steel rims for the test they wont be able to see the adapters through the rims... 
 

Also, without adapters or spacers I would have to find some sort of deep dish rims because Im guessing the offset would have to be quite large...
This way I can use more standard flush style rim and keep it close to the body.

What do you think?

Definitely not. Low profile tyres have no business on a Bedford. You need some more rubber.

[Bedfordcrazy]

I agree with rogue.

you could proberbly get away with the low profile tyres but you would have to drop it on its guts (lower to the ground),
