Obviously I will look stupid for this, but I run my tires way too much down on a road trip I’m currently doing. I’m driving 1700km (~1000miles) from the north of Norway to the south. The tires should’ve probably have been changed before I left. Either way, I’m stuck about 500km (~300miles) from my destination. Fortunately I managed to find new tires with the correct dimensions close by. But, moral of the story, don’t run your tires down like this.
Plenty of tread left on the sides. Just make sure to stay on twisty roads for the last 500 miles.
