I figured I would start a section width guide for the ST6/TT6 as a tool for current and future participants to develop their builds with information in hand, as opposed to having to guess on purchases prior to later find out that their wheel/tire combination doesn't fit their desired section width rules.

It's important to keep in mind that there are a variety of tires and wheels, which can subtly alter your section width results, while attempting to meet the section width template of your choosing. This is why wheel type and size are listed as not EVERY 15x8 wheel is EXACTLY 8" wide, nor do they all have the same lip design which may or may not make or break you meeting a section width template.

List your setup in this format if possible for accuracy:
Tire Brand/Model:
Tire Size:
Wheel Model/Size:

General Rules:

Preliminary information. 23mm references the 226mm template. 30mm references the 257mm template.

Fits 257mm template EXACTLY. This is so close that you REALLY have to account for mounting and manufacturing defects as you couldn't possibly have a more perfect fitment. The guage fits snugly, but does fall off easily. There is no space between gauge and tire.
