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?

I know that doesn`t help but they are sticky AND stable driving around on the street........ 72 Dart 470 n/a BB stroker street car `THUMPER`...Check me out on FB Dominic Thumper for videos and lots of carb pics......760-900-3895.....

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. 2001 Dodge Dakota 408 All Motor 11.27 @ 117.83 mph 2017 NM Mopar Challenge Series Champion.

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

Our car race ready is about 2800lbs on slicks. They are mounted on beadlocked 12" wheels and we DO run tubes. We normally run them at 12-13 psi at that weight. A heavier car will need more or it will absolutely CRUSH the sidewall at the hit Remember....MORE air, puts MORE rubber on the ground because it flattens the tire out and stiffens up the sidewall. Low air, lets the tire "cup" in the middle and has less rubber on the ground. We have been 1.09 in 60ft on this tire and 4.30s in the 1/8th at 173+ A high hp car that hooks hard and crushes the sidewall will beat the sidewalls out in short order. Our slicks are DONE for us in 12 passes, but would still be fine for lower hp stuff. Monte

Even on the radials, we usually beat the sidewall out before the tread is done. We are light on burnouts. Killing the tire on the burnout does you NO GOOD. With the car just sitting there, slicks or radials and I can see lines in the sidewall where they have been wrinkling......off they come. Monte
