You didn't say "cut". You imply the first signs of decomposition of the tire. If these are trailer tires o your rig, scrap them and go to LT tires. Check the deductible on your insurance policy to help you decide to upgrade. On the I-10 I saw a big rig trailer recap blow as a brand new RV was going by. I stopped as a witness. I gave the victim my mailing address. She later reported the damage to her Navigator amounted to $11,000 plus a couple of thousand dollars for hospital bills for her small boy riding in a car seat. That impressed me. Forget about the damage potential to your own rig and start thinking about liability for a multi-vehicle incident. Is it worth it?
I gotta continue this...about an hour after I got done filling out paperwork I heard a terrible noise so I turned down the radio. The noise slowly psssed me. It was a lady in an old SUV. Sticking out the filler pipe was a nozzle with about ten feet of gas station hose still attached. I had to pull over onto the shoulder I was laughing so hard. A couple of minutes later a couple of Blue Arizona Highway Patrol cars roared past, lights flashing, sirens yelping. I turned off the freeway a few miles later toward Ajo. Man! It's a nuthouse up there!
