are they the reg ET drags or the stiffwall... the stiffwalls have S after the numbers (28x10.5x15s) if they are the stiff walls I would run then no less then 12 and with the weight of your car I would run more like 14 and dont do monster burnouts... ET drags dont need big burnouts once you see ANY smoke pullout of the burnout box..... also make sure when you 1st get to the track and the slciks are dead cold run 1.5 psi lower then you want cause the pressure will rise when doing the burnout... check the pressure again when you get back to the pits they should be near what you were aiming for.... and after thety have been warmed up the 1st time they will keep some of the heat and you can just set the psi where you want... but to make sure always check the tire pressure before every run (i e going to lanes) and add air and relower if neededI was pleased. I REALLY liked how the slicks feel. They snatched the piss out of me!!! scary kinda! I learned alot. I need to drop from 12 pounds of pressure to about 10. Need to do my burnout in 2nd gear. But one thing was the 373's and 28" tall tire had me shifting right before the 1/8. Try to push it out but it was redlining too much.
And there was life support helicopter out there cause some lady passed out and wasnt breathing. So they shut the track down for a while for that too. Just a shitty night to go.
