Urgent - Need help fast

those tires are toast. You already got debris, salt, sand, snow, ice, and who knows what in there. It will now eat the tire from the inside out, and I expect you to be replacing the tires in several days.
Sorry about the bad news man. :(
 
What happened was an SVO owner was getting gas one day and noticed that he was missing a valve stem cap of his own (chrome of course) and trying to avoid peril he acted quickly and retrieved one of yours (unfortunately black) to replace his and to save the day.....feeling badly he fled the scene of the crime trying not to get caught.

BTW, do you want the cap back????
