hi, I guess I have a somewhat strange question which certainly can not be answered so easily, but what would you say would be the ideal maturation width? especially ground adhesion in all situations is a criterion – so not so very optical, but rather things like steering-easy-accessibility, sprite consumption, aquaplanning vulnerability etc. to name an example, so an increase in the maturation width from 145 to 155 would bring more than an increase from 245 to 255 (although both are only 1 cm is t) It is estimated that the sensibility of wider matures with increasing size will decrease exponentially – optically of course exactly turned around by the way a ford fiesta – the rule may however apply anyway to all cars of this class mfg Flinky
