Good Years or Phoniex?

Thanks Rick, I may call the manufacture.I hear do's and don't on tubes. I was running them, but left them out because I would need to drill the hole in the wheels for the tube stem. It is larger. They held air for 3 months so far. I got the new diff. together today, so I need to drive it to see how the tires clear.They are close. I would love to stay with the 13.5 wide ones, because they are still good.
Same motor in these 3 differnt cars, but the Daytona, and the Valiant have aluminum heads.
Here a pic of the Daytona.
