Is there a dependence of the rolling comfort on the load index(LI) of a tyre (with the same tyre size and identical. Air pressure/gas pressure)? I assume that the RF tyres (tires with higher LI) have more stable flanks and more stable belt/running surface(?) . From this one might conclude that the tyres with the lower LI should offer lighter springs and thus a better rolling comfort. Is there a general connection? Are the tyres with the lower Li also lighter? If they are lighter and better “springs” should also the rolling resistance and the fuel consumption be lower (?) . If the tire with the lower Li consumes less energy , this remains e.g. with a longer motorway ride also cooler than the tire with the higher LI ? Does the tires with the higher LI give more stability when cornering at the border of adhesion ? Can the tire with higher LI with slightly lower air pressure / gas pressure be driven than in the R. with lower LI and d Amit the rolling comfort almost equal in comparison to the tyre with lower LI ? (the legal requirements to the LI and axle load as well as the percentage decrease of the Li from a best. Speed are known to me.)
