| X1245 W/P - Sr. Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer}1/KW.7.7.36. Have you yet tried the altered brake leverage on your trials car ? We have been trying out some Bentley tyres to get more comfort and greater life. They are 6 x 17 on wider rims. I have asked Indias to send you out a set of tyres and rims for your car. We should like your opinion as to road holding, etc. You will have to find out what tyre pressures suit your conditions but we have been running at 28 rear and 30 front.
