These tire and wheel sets come glued and trued to optimize grip an tire contact patch. Trued tires are more consistent and more balanced than tires that are just "worn in". If you have never experienced the benefits of having your race tires mounted and trued before, you are definitely missing out. All tires are trued to (22.8mm With the exception of the S6, which are closer to 22mm) which is a great starting point for the majority of track conditions.

We offer the option of Truing Radial Tires because they are typically slightly wider tires.
