> Road wear grows at the 4th power of vehicular weight, assuming similar tire pressures. That's fascinating, is there an equation for road wear in relation to vehicle weight and other factors? --- EDIT --- Ten seconds after I posted this, I see somebody else also asked this question and there is this link. https://www.insidescience.org/news/how-much-damage-do-heavy-trucks-do-our-roads https://www.insidescience.org/news/how-much-damage-do-heavy-... The fourth power rule, I guess it was empirically measured.
