Tony,

The Matador is shown in the War Office vehicle data book as having 13.50-20 tyres, replaced by 14.00-20.

Looking at this book, 5th Edition 1945, it shows 10.50-20 tyres and also a new alternative marking 11.00-20 replacing 10.50-20. (same as the Matador tyres above). This now leads me to believe that there is no physical difference and that they can be mixed, hence in my previous post, the army part number is the same for both sizes of tyre.
This has now surprised me, because my Bedford was originally on 10-50 and now 11.00 and the speedo, which is a NOS, is out and I always assumed this to be due to the upping of tyre size, now I think the drive gear may be wrong, will have to check that out!

Richard
