Many thanks for Hs{Lord Ernest Hives - Chair}/Rml/LG4.3.27. We are advising all concerned in regard to this matter. We should be glad to know whether, in instances of Owners of existing 20 HP's with High Pressure Tyres, wanting to fit Balloons, there would be any objection to their fitting the 33 x 5.77 Tyre which you will see from the Dunlop list, is made to displace high pressure tyres on existing rims suitable for the former standard 32" x 4 1/2" S/S. Tyre. Will you please let us hear from you on this point. Sg.{Arthur F. Sidgreaves - MD} | ||
