Rim diameter inflation converting ordinary fitments into performance sizes
Vehicle designers moved to nineteen and twenty inch wheels for brake clearance, showroom proportions and electric platform packaging, and above roughly 19 inches no standard touring construction is offered at all. That converts family vehicle fitments into ultra-high-performance sizes without any decision being made about handling. Around 71% of the resulting owners never approach the speed rating they carry, and none of them chose it in the first place. The discovery arrives at first replacement, when a tyre costing about 2.4 times a standard fitment appears on a quotation. Nobody warned them.
