I thought it would be good idea to have a thread listing which models has which real world tyre sizes. So if someone looked up for example "400/60 R38" they would see which models have tyres in that size.
It is going to take a long time to compile but it would be good if we add sizes as we go along. So if anyone has the chance to measure their 1/32 model's tyres (or already know the sizes the scale tyres relate to) and add it to this thread that would be great, if you can in this format;
[real life size (if known)] - [type - i.e tractor] - [scale size i.e 12 mm x 55mm] - [model/supplier found on]
If you don't know what the scale size relates to in real life that doesn't matter, just post the 1:32 info.
This post can then be updated by myself or the moderators which will allow discussion to happen below.

It may look a bit complicated, it does give out more infomation than maybe you need, but you can enter as much or as little as you like. Its best just to pay around entering numbers into the boxes. You will need an understanding of how tyre sizes work, I'm not the person to explain that, try google.
It will convert real mm and inch sizes to 1/32mm and hopefully vice versa, but you will need to round to the nearest real size, look at it as a ballpark figure.
I think another thing to consider is tyre wall flex and loading, heights from the calculator are precise, in the real world they would be less.
If I have made a major error, please let me know.
If you do use it to scale a 1/32 tyre, I'd appreciate the data so that we can add it to this list.

1/32 Rim diameters round to whole MM.
30 inch rim = 24mm
32 inch rim = 25mm
34 inch rim = 27mm
38 inch rim = 30mm
42 inch rim = 33mm
