Prvega ne verjamem brez prepričljivo utemeljene razlage. Pri drugem dvomim, da gre za bistvene razlike. Predvsem pa najbrž nič večje, kot je med raznimi tipi gum enakih dimenzij za enak avto, ki imajo različno obrabo.

Tight regulation of exhaust emissions by the EU has meant that new cars emit very little particle pollution

But tyre wear pollution is unregulated and can be 1,000 times worse, finds independent real-world testing experts Emissions Analytics

Increased popularity of SUVs, larger and heavier than standard vehicles, exacerbates this problem – as does growing sales of heavy EVs and widespread use of budget tyres

Fitting only high-quality tyres and lowering vehicle weight are routes to reducing these ‘non-exhaust emissions’

Hvala. Naj o tem kaj več povedo tehnično podkovani sokletniki. Jaz bom repliciral samo na tale del teksta:

Using a popular family hatchback running on brand new, correctly inflated tyres, we found that the car emitted 5.8 grams per kilometer of particles.
Compared with regulated exhaust emission limits of 4.5 milligrams per kilometer, the completely unregulated tyre wear emission is higher by a factor of over 1,000.

Navedenih 5,8 grama na km ob približnem evropskem povprečju 15.000 km/leto pomeni 87 kg (5,8 * 15000 / 1000 = 87). Če gre res za obrabo gum in zavor, bi po pobalinskem dojemanju zadeve avto po enem letu ostal praktično brez gum in zavornih oblog. Ena guma za "popular family hatchback" zagotovo tehta manj kot 20 kg, zavorne obloge za štiri kolesa pa manj kot 7 kg.

Sem samo neveden, nor, ali pa je z izjavo teh strokovnjakov res nekaj narobe?

BTW, firma je bila ustanovljena pred 9 leti, v njej so kadri iz medijskega biznisa, pa znajo o svoji zgodovini, dosežkih in referencah skupaj spraviti samo tole make-believe petvrstičnico:

Emissions Analytics has rapidly established itself as a global authority on real-world vehicle emissions. It has done this through vehicle emissions testing using Portable Emissions Measuring Systems (PEMS), resulting in a proprietary EQUA Index test cycle allowing the comparison of real-world performance of vehicles. The resulting database is the world’s largest commercially available real-world emissions database, the EQUA Index.
