Excerpt from The Autocar Imperial Year Book, 1913: For Circulation in the Colonies Overseas Dominions and Abroad Competition between car manufacturers to list chassis at what are supposed to be popular prices has resulted in many cars being fitted with tyres too small for the work they are expected to do, a short-sighted policy which frequently proves most expensive to the owners of such cars. If. The tyre bill is to be kept reasonably low, tyres Should never be loaded beyond the maximum Specified by the tyre makers for the section employed. To comply with this condition the normal load Should not exceed 80 of the carrying capacity of, the tyre, leaving a margin of 20 for the occasions when extra passengers, luggage, or equipment are carried. A Palmer Cord Tyre, 810x90, inflated to a pressure of 801bs., will carry a load of 8 cwt. Per wheel, but if the normal load on the back axle of a car fitted with this or any other diameter of 90 mm. Tyre exceeds 14 cwt., it will be found far more economical to fit the corresponding diameter of 105 mm. Section, which is designed to support a load of 10 cwt. Per wheel when inflated to 80 lbs. Pressure. For an axle load of 16 cwt., the correct pressure for 105mm. Tyres would be 64 lbs. Against the 80 lbs. Necessary if a similar load has to be carried by 90mm. Tyres.
