Talk:Nomenclature for tyres

Unit of Measure differences ?

Why are wheels and tyres in mm but screws are in LDU? ++Lar: t/c 17:47, 11 July 2011 (EDT)

I don't know. Are they? Have to investigate. --Mikeheide 00:46, 17 July 2011 (PDT)

They seem to be... see Nomenclature for screws. ++Lar: t/c 12:10, 17 July 2011 (PDT)

I have take that from a part on the PT. I think Chris has written that. But I see no reason to change as measuring in mm/inch is quite more difficult. With this approach you can much easier find a screw that already exists and fit your needs. IMHO.--Mikeheide 00:07, 23 July 2011 (PDT)

So maybe it's wheels and tyres that are the odd man out then. Changing them is more extensive I suppose. Also many LEGO tyres have the size imprinted/molded in the rubber. ++Lar: t/c 05:57, 23 July 2011 (PDT)

We have a mix of units across the library (studs/brick height units/LDu/actual) and it doesn't make sense to use a single unit for everything. I deliberated long and hard on the tyres, to help solve the problems of small/medium/large that existed. In the discussion at http://news.lugnet.com/cad/?n=13760 I decided to go with something that most closely matches the commercial (ISO) nomenclature, which is in some cases used by LEGO.

Thanks for the explanation, and yes that's how replying works... talk pages are just like any other pages (unless the wiki has installed Liquid Threads, which this one hasn't and which I advise against). Note, you may want to consider setting your signature so that when you go ~~~~ in your post it autoadds a signature. Mike and I have that set already. It's in your preferences. ++Lar: t/c 11:31, 21 August 2011 (PDT)
