We've recently changed over to stiff sidewalls. Only did 3 passes before hurting the motor but I can tell the car did not like 11.5 psi in them (on my gauge). Car squirmed around a lot from the startline. We started @ 12.5 and went down. Next time out we'll start there and go up, tyre was wadding pretty bad in hindsight. Got a 1.41 60ft but track wasn't there, so everyone was saying, so it sorta equalled the non stiff wall slicks given the conditions. I think the normal slicks are a bit more forgiving when it comes to pressure. We still run ours with tubes too, is this right?

If it is dropping off from the 330' on I would look somewhere other than the tires.

I put 10,5 Hoosier stiff walls on my Dakota this year. It hates them, nothing I can do will make them work. Truck weighs 3400 with me in it, but 500 lbs heavier on the nose than the rear.
I've battled them for the last weekend, they are coming off tomorrow in favor of the regular side wall Hoosiers. My 60' is down, my ET is down but I sure love the way they launch, I just can't make a full pass on them, the rear end starts to skate around going down the track, but our track has some serious issues too.

... could be over reving the engine on the top end.. if you put on a taller tire might do it or a gear change... this is just a guess if you are over reving... I know I am a little.. I run a best 60' of 1.19 but the normal is a 1.21 and 8.96 at 152 best but normal is 9.01 at 150... I know my cam is way short on lift

12.5-13.5 for me with the 3062W, shares the same sidewall. No more radials on yours?
