I had a question about tires. Ive recently gotten into spot cars, mainly Carrera Digital 132. As I've found, the best way to get cars is through Facebook marketplace. Problem is, some of these cars have flat tires and are hard. Like they spin on the track rather than move. I have 2 questions. First, does changing the front tires matter that much? Like I figured it's mostly guided by the sled, so idk if it's help it hold a turn better or not. Second, I got quick slicks for replacement tires. They seem to be the only ones I could get my hands on. Anyone got any good suggestions as to where I can get more tires? I have quite a few that I need to replace. Thanks for any help you guys can provide
