Indeed. I have even seen a tyre sidewall marked "11.00-20 replaces 10.50-20". I have since learned this was a "new alternative size marking" for the 10.50-20 tyres listed in the wartime Data Book of Wheeled Vehicles, so it must have been a wartime change.

Hanno,

Looking in the War Office Vocab for Tyres, dated 1951, they show tyre part no. LV6-MT14 / 7297 ( with CC tread ) as being supplied as;
a/ 10.50-20
b/ 11.00-20
c/ 10-50 / 11.00-20

Incidentally, regarding runflats, only 10.50-20 are listed..........no 11.00 at that time.
