It seems to me that they were underinflated. Jason, the 2 marks you see on the side of the tire means that the middle part created a pocket and the wheel was only touching the ground with the sides of the tires. I think, hehe.

i'm pretty sure that it means they were under inflated, I just wanted some expert opinions. I know everyone says they run 17 or 18 psi and i was running 18 or more. I know i didn't go under 18psi. but i guess different tires on different cars will not all be the same.

20 psi in REAL SLICKS I dont think so. Thats crazy. That would be OVER inflated.

What exactly are those ?

kinda look like M&H's or some Et streets.....

I stated over inflated, because i haven't seen anyone at the tracks i go to run more than 16 psi in slicks.....BUt that is gonna vary by the cars weights etc. so i was just throwing out a guess..... maybe someone with personal experience will chime in.

they are hoosiers.

stangfreak, you say that is too much tire pressure but doesn't the wear pattern say otherewise?

I aint no pro here and cant tell whats going on by looking at them sorry. But thats too much pressure imo. From what I know people put between 7-12 psi in them usually.

Thats a wear pattern from underinflation. It they were over inflated the middle would be worn more.

if you are running that much air they are over inflated.

slicks dont cup like a steel belted radial will...

I agree. We all know this from the typical tire wear .....

1.) Over-inflated = tire wear in the middle.

2.) Under-inflated = tire wear on the edges.


Now notice on his, the wear is NOT on the far edge, NOR is it in the middle. I say they are OVER-INFLATED.

exactly. They do slightly in EXTREME circumstances but not like that. 18-20 is too much psi IMO. Don't look at the wear pattern of your drag tires to see the results....LOOK AT YOUR 60ft TIMES. Find what works.
