Why didn't the shop who took them off clean them?? That was part of there job.
Goo Gone will not hurt your tires, did you ever just think of how tough a tire is? And all the stuff it runs over/thru in its life? GooGone works on your hands. Tire should survive.
Hey DW (no pun intended in reference to the NASCAR great), pardon me if I sound like a smart a$$, but hey, I am, and you asked, so here goes: To answer your first question, I have no idea. My bad. I should have checked and I didn't. I was in a hurry to get back on the road and up to DC for Rolling Thunder, but that is absolutely no excuse for my failure to be responsible enough to check and make sure they completed the job. To answer your second question, no, not really. Never occured to me. To answer your third question, no, not really. Never occured to me. As for the GooGone stuff, Dude, I don't even know what that stuff is, but now I do, and now I know, so I've banked that knowledge for the next time I have my cranial cavity in rectal defilade and forget to make sure the shop removes the residue. That way I can run out to Wally World, pick up a can/tube/jar/whatever vessel it comes in and go to work without wearing out my fingernails. But it is all moot at this point as I've worn out my fingernails and accomplished the mission!!

Oh, hey, do you know anything about what WD40 and acetone does to tires? If you do, please enlighten me, so I can bank that knowledge as well. Thanks Bro!
