what size et street you running? Next time you go put the pressure @ 12psi and start there. Keep in mind after a couple of passes the pressure will swell 1-2psi. If you still don't hook there then inch it down a little from there. You will get a little squirly on the top end but if you don't twitch the wheel when you shift and you stay in it and slowly correct you will be fine. You'll get the hang of it. I have probably made 200+ passes on et streets with a straight shift(car). One key thing is to find something to prop your left elbow on, knee or door panel, to keep it steady and you don't jerk the wheel with your body while you are banging gears. I have ran as low as 8 psi on a set of 26x10.5's. It is a wild ride but that is what it took to hook

 

DAM! I was all over the place on 15-18, I did not like it at all. If I dont hook after I try the second gear burnout, I will give it a shot. THanks. I have 28x11.5x16's. I can toadly tell the tires are flat, It is harder to roll. When I first put them on I thouhgt I had my brakes on. I hope I dont have to go that low, I think my top end suffers. Maybe not.
