Also, the Wartime 10.50-20 tyres were replaced post-war with 11.00-20, but it seems to be just a name change as dimensions and ratings remained the same.
And 9.00-16 and 9.26-16 tyres have identical carcass dimensions, but the 9.00 size is for "British" rims, while the 9.25 is for the tapered seat rim used on the C8A and Lynx, aka "American" rim. |

Here is a photo of my new 9:00x16 tyres next to a slightly worn 9:25x16 tyre off my Lynx. You can see the 9:00 is taller and also narrower than the 9:25 tyre. Lynx Continues Tyres 024.JPG The new 9:00x16 tyres did drop onto the Lynx rims very easily. Regards Rick.

I do have 2 WW2 Canadian 9.25 tyres and the carcass size is the same as Canadian and English 9.00-16 tyres I have. However, both 9.25s are from different manufacturers and while the tyre widths are the same, the tread widths are different I also have two near-new Australian made 7.50-16 bar tread tyres (from Land Rovers) which are over an inch in difference in diameter. The point I am trying to make is that tyre sizes are indicative or nominal, and are intended to provide more information than simply the physical dimensions. |

Also, the 9.25-16 sizing seems to only be a uniquely Canadian idea. English-made tyres (WW2 production) for 5 degree bead seat are designated "9.00-16 for American Wheels".

I believe the 9-25 X 16 was also used on British Humbers , the 4X4 FFW PU and the Box ?
I tend to agree with Rick, the 9-25's had a lower profile ( nothing to do with brands ) and this low profile was a deliberate design spec. .

Hi
This is interesting considering we were all feed the line over the years that the Allies won because they standardised everything and the Axis lost because they could stop inventing and re-inventing things. And yet here we are with two tyres which on the surface would seem too close to one another i.e 9.00 and 9.25 to bother with, yet they did it and produced both. Can't imagine in the heat of battle and looking for a spare tyre I'd have been too choosie!, not like I'm going to be stopped for a roadworthy as I'm rushing forward from El Amein or worst back from Tobruk!! |

Quite correct, and the Humber Scout Car was also on Runflat 9.25-16 tyres. I have driven a Humber Scout on 9.00-16 and it is considerably more high geared due to the increased circumference. Especially awkward when trying to get it up on the neck of a low loader semi-trailer.

Hi
So what was the reason for 9.25 x 16 versus 9.00 x 16 surely when they were trying to keep rubber use to a minimum one tyre would have been easier to produce, Was it something to do with weight carrying capacity, they were both off road tyres right, so there would have been no need for different performance characteristics surely. Was it something to do with the 'run flat' requirement on armoured cars etc. regards Matt |
