Joe,
I paid $90 but I didn't mind because Mike was very thorough and took the time to answer all of my questions and explain everything he was doing as well as letting me sit in the car and be back in the shop while he was doing the work. I also received a printout with before and after numbers.
A side note about Tire Kingdom, Don't use the one in Plant City. I took my OEM wheels there a week before the alignment to have my new tires installed and they ended up damaging two of them. Of course they said the damage was already there and after arguing with them for an hour, all they would agree to do is have the two damaged ones repainted. Well I didn't want them touching my wheels any more and if they are to be refinished, I want to have them all powder coated and not painted. Anyway, to make a long story short, they gave me my money back and I will never use them again. Just wanted to share that.
Mike at Advance does tires too and specializes in big (20"-24") wheels and low profile tires. I will be going there for any future tire mounting needs as well.
