Also, speaking of tire shops... Want to get a funny "are you a complete idiot look" from a tire worker? Yesterday I went to discount tire and asked if they could lugcentric balance some wheels for me. They started walking towards my explorer and say "let me see what you have going on"... I stop them... It has nothing to do with that vehicle. Simply, can you lugcentric balance wheels? Yeah we have a similar process we can do... Okay thanks let me go grab my wheels. I pull out 4 wheels, no tires mounted on them. The dude's like uhhhhhhhhhhhh... I look at him, can you balance these for me? Uhhhhhhhhhhhhhhh well sir, that won't work, you need to have the tire on it to get a true balance. Yeah, no joke dude... Don't worry about the tire though. Do you want the job or not? If you do, slap these bare wheels on your balance machine and spin them up... If you don't want the money I'll go elsewhere. LOL
Wouldn't you know it... Turns out the new fangled machines know if there is or isn't a tire mounted to a wheel and they can't actually balance just a rim if you ever wanted to. How's that for some useless knowledge!
