Are ceva daca se pune pe o masina de 1480kg niste cauciucuri cu indice de greutate 90/91 (suporta 600-615kg) in loc de unele 94 xl (extra load - suporta 670kg) ?

Parca greutate indicate la cauciuc se refere la greutate suportate maxima la viteza maxima admisa de cauciuc. Deci chiar pot sa depastesti greutate indicata, cu conditia ca nu mergi cu o viteza mare. E un trade-off. Cred ca are legatura cu caldura generate din cauza frecare / deformare de un cauciuc cu o viteza respectiva si o sarcina respectiva. Si, inca ceva, la viteze mari forta pe cauciucuri e mai mare decat greutate masinei, ca apare si downforce din cauza aer-flow.

Poate mai stie cineva mai exact cum e..
