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.

Interestingly, while this tyre originally had Dunlop TrakGrip tread, it was recapped at least twice, the last time with NDCC bar tread.
