Ignoring the rationale of this politicians thinking; lets look at
tire rolling resistance. That website/subject, when read entirely, clearly denotes that tire design and compounds are a small factor in actual total rolling resistance. Perhaps the Governor should make it a priority to improve roads first. It makes a strong point that road surface in the largest rolling resistance factor; then tire width/hieght.
If this article is true, auto makers should never have began using larger diameters. Perhaps we should revert to 14" tires for autos.
I should enter RV's into this to stay in terms of service. Whether it be a LDT, MDT, or HDT; I think tires to carry sufficient load can be bought in narrower sizes adequate weight ratings
