Guys with lifted trucks run a set of street tyres because:

They can't get into their garage on big tyres

Getting in and out daily is a pain

MT tyres are noisy and that makes them thirsty (all else being equal)

The tyres themselves are expensive and soft off road compounds may not last, you can't run them down to minimal legal depth and expect them to work in the mud too

MT's have poor traction in anything but mud

Etc, Etc


If a truck's been re-geared with 4.56, axles or lower to turn those big tyres it will rev it's nuts off on stock tyres.

Plain & simple :

Car manufacturers that make "eco" versions of cars, use thinner wheels than usual.
Example : VW electric up!
One some cars over here, you couldn't get different optional (read: wider) rims because that'd increase the CO2 output beyond the limit that made the car qualify for a government sponsored discount.

On dedicated eco-vehicles, thin wheels are used - period.
Examples : VW 1L / BMW i3 / Renault Zoe

They've known it all along ...
Remember VW's Beetle had jolly big, narrow rims.

Wider tyres also scrub more when cornering - and you pay for it in fuel use.


If wider tyres would give a fuel consumption benefit, they'd be used on those dedicated eco-vehicles or more economical (or ecological) versions of "standard" vehicles.
But that just ain't happening.
