There is a mobile jetty used by Blue Boats at Southsea, about 100 yards from the RN Memorial at Southsea Common, Portsmouth, Hampshire. The jetty runs down the steep shingle beach into the water when required. The landside pair of the four wheels are military style with quite good condition 11.00 x 20 Dunlop Trak Grip RFs! The others are worn India 20-inchers.
Was the 11.00 x 20 a later version of rhe 10.50 x 20?

David,

Running a Bedford QL, I can answer that. The size 10.50-20 was used on 4x4 3ton trucks during the war period and runflat variants on armoured cars such as Humber and Daimler. Post war, I would guess in early 50's the 10.50 became obsolete and replaced by 11.00-20. I have an army pamphlet on servicing the QL, c.1958, stating this point.
The RF tyres you spotted were probably from a Saracen APC.
