| X.1238 S/W. Hs.{Lord Ernest Hives - Chair} Hs{Lord Ernest Hives - Chair}/TB21.12.20. X 1238 Re - Rapson Tires. Your Hs{Lord Ernest Hives - Chair}/TMW4/LG16.12.20. We note the points you give with reference to these tires to help us in dissuading customers from fitting them. Point No.2., which gives the cost of the tire, is only serviceable if we can quote some figure for the life of the tires tested by us. We presume you will continue to test the tires you bought until the end of their life, so as to be able to give us the useful figure required. In connection with (1) The unsprung weight, and (5) Vibration, I presume we may suggest these evils are detrimental to the back axle and its gears. H.{Arthur M. Hanbury - Head Complaints} | ||
