Hoosier compound question

Rory McNeil · 02-08-2016, 04:17 AM

Anybody familiar with the compound ratings of Hoosier drag slicks(non radial). I am looking at getting a new set of Hoosiers soon, and was curious about any differences between the "CO" and "DO" compounds. The tires I am looking at are available with CO6, CO7, DO6, or DO7 compounds. I have used the 9x29 DO7s on my stickshift Stocker and liked them, I understand the DO7 is the "stick" compound, but I can`t find where the CO7 fits in Hoosiers ratings.

The "Soft" to Firm" chart is at the bottom of the first section. But you may need to call Hoosier directly to find out the difference between CO and DO.

Robbie,
Are you sure about that? All of the 9" Stocker radials are "CO" compounds and I've always heard that radial slicks and stick cars don';t mix, at least not on Stockers.

I believe "DO" tires are Bias and "CO" are radials.

We run CO6 on our High HP cars and CO7 on lower.

CO7 last longer for us.

Radials work fine on our 10 sec. Super Stock cars with Transbrake...
....Suspension must be working right.

We are faster on Goodyears.
