The 32.0/4.5-5 SH will measure approximately 31.5” on a 5×5 wheel at 8 psi. Compounds available in this size include D20A & A35.
D20A is slightly tougher than the D10 and works well on crumbs or marbled tracks.
The A35 is a high traction compound that will work well on tracks that lack grip, such as colder track conditions, slick or green track surfaces. The A35 will grip quickly with little heat and will be consistent throughout long green lap runs.
