That's insane. I don't understand how some people can be so blind to safety. Maybe you can do them a favour and sneak around one night and slash the tires?My Grandad passed away in 1999 and hadn't driven for at least two years before that. 2 years ago my Grandma finally passed away and I was given their 1994 Chevy Lumina 3.4 Euro with 31,000 km's on it. The thing had been sitting on flat tires for at least 6-7 years. After working on it for a week getting it back up to snuf, my Aunt decides that she wants it and because she's more entitled to it than me. Convinient that after all the work is done to get it road worthy, she know wants it.
Anyway, like I said the tires had been flat for YEARS. All they do when they pick it up is fill them with my compressor and go about their merry way. A week later they're still running on those tires but no matter how much I told them to get new ones, they said they were just fine. About a month later I get a call that my Aunt was on the highway and the drivers fron tire blew. She wasn't hurt or anything but it was determined that the age and condition of the tires caused the blowout. They replaced the front tires and to this day are still using the originals on the rear. I'm waiting for another phone call.
Sorry for the rant.
