Shit, that reminds me -- I need new tires. They were supposed to be 70K tires, but I only have around half that. Didn't align them, didn't rotate them enough, didn't take care of them at all, so in my case, it's my own damn fault.
Your look like they're completely worn through on the inside, so I presume you didn't see anything, but didn't you hear anything? Or was it overshadowed by your car stereo?
