DUNLOP FLAT TRACK TIRES

Dunlop has provided the inflated profiles for their flat-track tires - the new tubeless DT4's and also the pre-2020 tubed DT3's.

---

Below are are graphical comparisons of the inflated profile for each tire on different rim widths, and also DT4 vs DT3 on the same rim width.

These profiles are generated from laser scans of the inflated tires, and are different from the rolling radius curves that are intended for traction control.

The MotoSPEC PRO license has the ability to calculate chassis geometry with lean angle, considering the tire profiles.

The profiles are assumed to be rigid and non-deformable.  The radial stiffness specification for the DT4's may be available in the future.
