If there is no problem that is fine. There is not much we could actually perceive from that photo. I was just concerned that you might end up paying for welding then need new suspension. If that had of been the case then unless there was a desire for a renovation project the best option may have been scrapping then buying something else. Glad there is no problem beyond the welding.

It's not just the offsets although I'm still uncertain if we measured this as 24mm or 1" (25.4mm) See
[You must be registered and logged in to see this link.]The initial Mini wheel was 3.5" but there are also 4" and 4.5" Mini wheels. Pitty I don't read all that I provide links to. I see that 1960s standard wheels had an offset of 29mm whereas 1970s had 24mm though that 5mm difference shouldn't be critical it would be noticed.
Mini 10" wheel options
[You must be registered and logged in to see this link.] Interesting wheel and tyre combinations. 1st shows 25mm offset 2nd seller shows a 23mm offset on Mini wheels but also sells 145x10 tyres on 5.5" wheels, illustrating the range of tyre widths it will fit.
[You must be registered and logged in to see this link.][You must be registered and logged in to see this image.] I thought all mini wheels were the same - they aren't and have different offsets. I had the same clearance problems with mine solved with spacers bought off ebay. (If you were really naughty you could put bid washers behind the wheel nuts but not very safe).
Looking at the above I can see that if the spacer is just allowing for the right sized wheel and tyre but with too big an offset then the forces on the hub wont be any greater.
The non math side of my head does get the willies about using spacers as the studs are only
3/
8ths and are very susceptible to failure. I tend to think a few wheels that have been lost have been post tyre fitting and it's windy guns being used rather than the nuts being torqued to 42lb Ft
The use of washers would be very naughty I think. The wheel is attached by the frictional force between the back of the wheel and the hub. there is no scissor like force on the studs. See the top of this
[You must be registered and logged in to see this link.]Now while theoretically the coefficient of friction "μ" is not dependant on surface area
[You must be registered and logged in to see this link.] I'd not want to change the amount of surface in contact nor and perhaps more concerning add multiple plates (The washers) that could slide on each other.
Sorry Hanna if I've not read deeply enough into your posts or thought about what your problem is. Just read some of your posts again. I was side tracked by your mention of angle iron (OK angle aluminium) which in fact is only a few mm.
[You must be registered and logged in to see this link.]The measurements you give are taken from the tyres not the measurements of the wheel. See

hannah3dog wrote:Hi Retro yours sound to me as if they're trailer wheels with no offset. I did the following measurements with 145 R10 tyres. Put a straight edge from fattest part of tyre to fattest part of tyre and measure to flange.
Mini Wheel 1 23mm offset inside 41mm outside 90mm (Just rubs because I added angle which is why no good to me)
Mini Wheel 2 30mm offset inside 35mm outside 87mm (No good at all fouls chassis)
Std Trailer Wheel 0mm offset inside 67 outside 67 (Gives 30mm clearance)
Its all a bit confusing. Yours will probably take standard mini wheels 23mm offset which will move them inboard and were the wheels (as I understand it talking to Ian at Riva) originally fitted. But beware I got some with 30mm offset which won't fit!!
If the trailers handy just put a straight edge across the tyre and measure into the outer face of the flange. Its all very confusing!
I'm reading that you have three wheels that have tyres mounted where the width is 122mm, 131mm and 134mm. 12mm in difference is one wheel
1/
22" narrower than the oter two or is that amount of variation reasonable on the same rims?
You say one is 23mm (Is this marked?) but the inside measurement is 41mm and the outside is 90mm.
90 - 41 = 49 divide by two is 24.5 so that is within tolerances of measurement but if the
outside is 90mm you have a negative offset so I'm left to wonder if you had a wide wheel because I don't see how you could have fouling with a negative offset.
An original 3.5" wheel has a centre at 1.75 inches or 38mm but if the centre is offset by 23mm it's 61mm to the inside edge.
If you had a 5" wheel it's centre is at 2.5 inches or 63.5mm and you have a negative offset of 23mm so it's only 40.5mm to the inside edge.
I'm sure you would have spotted if you had thunderous 7"" wheels on. My earlier thought was that you had something like the Dunlop LP 882 wheels with a 47mm offset which would make everything fit or more correctly not fit perfectly. Alas it also doesn't match the offsets you have read on the wheels and the wheel in your picture that is deeply dished is at least a neutral offset if not a negative offset.
[You must be registered and logged in to see this image.]It has now just come to me. look again at my line of maths for showing the inside edge of the wheel.
hannah3dog wrote:Hi Retro - well I'm completely baffled as your Dandy 4 looks the same as mine and those wheels in the pictures look like mini wheels.
I've added a 1.5mm thick angle to the bottom to tidy it up which reduces the clearance and on one side a 23mm offset min wheel rotates (just) but on the other it (just) catches the chassis. There is no way I have 1.5" clearance! Without the angle they would both rotate with say 5mm clearance
My drum faces are 40mm from the chassis - I'm wondering what yours are. I think judging by the age mine are the original running units
I did think about putting in spacers but they will need longer wheel bolts and I'd have to disassemble the hubs and disturb the (new) grease seals. Also I'm nervous about getting the wheel bolts out of the brake drums. Its a pity as I already have mini wheels on a boat trailer
Hence my query about 500 tyres - they don't need to be much narrower than the 145. They work as is but narrower would be better
If the standard wheel depth is 61mm I think we can guess at something more than 40mm
A bad day at Dandy but they then fitted different wheels or someone fitting new units or welding up in the wrong place after repair? Are the suspension units welded on as per the early suspension or bolted on? If bolted check the position of the bolt holes against what they should be. It could be an odd set of suspension units.
This is more of a reply to you than the OP I'll tie it up with your older thread after a few days.
