Does anyone know what the heat range should be between a slick and the track after a burnout should be? I"m trying to figure out if I'm heating the tires too long or it's the hit of the tire. I've tried shorten my burnout. Starting out in 2nd gear, hitting fast and soon as I hit 3rd I let off the line lock and taking it to the line. I use Hoosier and they are looking like I took a cheese grader to them. They are ruff ,but even all the way across. The top of the lettering is starting show a little brown color, like they are getting to much heat. 60"s foots are varying because need of a anti-roll bar on it bad. Hopefully this week.

IIRC..my uncle crewed a stick shift superstocker, at 148* the the tire was useless.

He would shoot the laser on it after the burnout.

DRAG SLICK COMPOUND AND BURNOUT SPECIFICATION SHEET

CURRENT COMPOUND SELECTION AND APPLICATION GUIDE
The compound number can be found in the serial number on each tire.

EXAMPLE: CY1J M5 FJ087 M5-Compound code.

Mickey Thompson tires are compounded by size and application. The following points are general application suggestions. Mickey Thompson is not responsible for misapplications.
The catalog number suffix indicates a construction, size or compound enhancement for particular applications.

R = Radial construction
M = Motorcycle
C = FWD / Sport Compact
ST= Suggested for manual transmission (Medium compound – M5)
W= Extra tread width (please note actual tread and section width on spec sheet)
S= Stiff sidewall construction. Recommended for 4 link suspension cars, heavy cars (over 3000lb.), and "soft ride" Rear Engine Dragsters. Can aid in quicker reaction times due to less tire distortion.

MICKEY THOMPSON COMPOUND SELECTION CHART
Medium----------------------------------------------------------Soft
M7 M5 M8 R2 R1 L8 L7 B2 L4 M2

B2 - For motorcycles.
L4 - Soft compound for Dragsters, lightweight vehicles and vehicles without rear suspension.
L7 - For motorcycles.
L8 - Good compound for general use.
M2 - For Jr. Dragsters.
M5 - Good compound for general use.
M7 - Good compound for general use.
M8 - Aggresive Compound for Index Racing, Works Well in All Ambient and Track Conditions.
R1 - Special Compound for ET Drag Radial.
R2 - Special Compound for ET Street Radial.

BURNOUTS- FOR MOST APPLICATIONS
The length of your burnout will be dictated primarily by the ambient and track conditions. The hotter the temperatures, the shorter the burnout. When the temps get cool, a longer burnout will be necessary. Ideally you want the tire temp to be within 15 degrees of the track temperature on the launch. When the track temps exceed 120 degrees, it is always best to keep your tire temps on the lower side. Here are some additional tips for maximizing the performance of your M/T racing tires.

1. First pass of the day will be your longest. After that follow the guidelines of #2 and #3 stated below.
2. Automatic transmissions and Bias tires with Softer compounds: First pass or two, fairly hard burnout relative to ambient conditions. After that a light burnout should be sufficient.
3. Standard transmission and Radial tires: Typically shorter burnouts are better. A light burnout, enough to haze the tires, then stage immediately.
4. No dry hops. This does nothing to improve traction, and in some cases can have a negative effect.

I have been changing things up a bit and have found less burn out in the heat works.
Unfortunately our track sucks...

If the tires look like a cheese grater has been taken to them, it sounds like you need a harder compound. The right tire should have a kind of wavy pattern but shouldn't have any raised rubber. In other words, it shouldn't look like an old sweater. The tread is tearing apart and that is not good for traction.

That's the problem with Hoosier in the 31 & 32" tires most compounds are d05, which are there soft tire. I would probly have go to another brand. I have always ran these tire brand for a long time and had no problem, but with this new motor there's alot torque. I don't think they last as long. I did notice my 60's foot times are slipping abit from 132 to 1.37 . But the track was a little greasy. As ruff as those tires looks you wouldn't think they were slipping.

[Elarson]

We started out with Hoosier D05 compound and they were fine until we started to make good power.....then the tread started tearing up. We switched to C07 and it made an instant improvement.

Not sure what width you're using, but I just looked at the Hoosier chart and there are some C06 and C07 compound tires in the 31 - 32" range. Talk to the factory and see what they recommend. Look on their website under drag tires "Contact Us" for email and phone #'s.
