I love how you talk to one guy and he tells you one thing and someone else calls and gets a diffrent story. I think some of the people at these companies just waist peoples time just telling them anything right or wrong.
I bought new set of micky thompson slicks in Feb. that were out 3/8 of inch and call up and was told the same thing as what you are doing and check the roll out the next day and was dead on. I also ask the best way to brake in the tires as new tech changes allthe time.
Good luck hope they work out for you.
