Dear Mr. Grylls, Thank you for your letter of August 27th giving us the dimension which we asked for. The figures on relative cornering power are very interesting. It would seem to me that the 6.50 on the 5" rim would give a larger road contact which would account for the increased figure. We will make a check on this to see if we can determine the reason for the difference in figures. We should be pleased to have information regarding the slip angle at various accelerations. Yours faithfully, INDIAProduction 20 HP. with 4-speed box and Front Wheel Brakes TYRE & RUBBER COMPANY LIMITED. Pane Luntte Works Manager. | ||
