Tyre design All the vehicles on our roads lose a good amount of fuel through various means. One of the reasons is loss due to tyre friction. This article discusses design changes to reduce this loss without any drawbacks.TypesHere, we employ 2 different kind of tyres.AdvantagesApart from the obvious advantages, we get the following too:? Better ride comfort as application of 8 tyres instead of 4 gives better balancing overall.? Evasion of potholes on roads, gives better life for tyres. ? In case of a punctured tyre, we can keep the high friction tyres inflated (eliminates the need of a step in tyre.)? Avoid variations in inflation pressure of the high friction tyre. Contributes to higher fuel efficiency.? Usage of fluid instead of air decreases tyre operating temperature extending life, increasing efficiency and overcomes compression problems with air.Possible improvementsThe fluid used for inflating can be an oil thus providing cooling as well as lubrication for joints under rotation when it is pumped.
