i watch the video. one KEY point,when new tire at front, driver will NOT feel hydroplaning until it actually happen. (and already too late)when new tire at the rear, driver will feel hydroplaning THROUGH STEELING WHEEL and make adjustment according to situation (for example, slow down)
總歸輪胎該換的時候就換,也是要作輪胎調位.新胎排水和抓地力都比較好,裝後面可以降低打滑的機率.但後輪的胎膠還有50%以上,我想有必要把這條胎換到前面用嗎!我開過的感覺胎膠磨快到換胎緊警示線,抓地力和排水性真的很差.下大雨的時候,就可以感覺浮水效應.所以我的胎磨到那一定去換,
