Very nice!

 

i think 16 to 18 psi won't hurt you. 13 seemsreally low, i ran 12 psi in my dads car and it swayed like **** on top end, and it only ran 12.76 @ 106.

 

next time im going to try going up every pass and see what it does.

 

damn it launches good though. i agree it could take some more air...i also think those tires are alot lower than 13 psi. i would serously check them with a different guage and see where they are at. my last time out i set my 28x10's as low as 10 psi trying to get it to hook and they never did that...ofcorse i never got them to hook like that (zero track prep). never seen these tires flaten out like that though.

 

i dont know the brand of the gauge but its a very common gauge with the Super/Pro guys and i was setting at 13psi!!!! I dunno i guess its just hooking good
edit: i also checked it with some cheap gauges to see if it was off any and they all read 13

 

are you using a tube?

 

EEEEKKKK....up to tire pressure!! nice runs!!

 

Nice run! You could stand a bit more air try upping the psi 2lbs at a time until you break traction, then let it back down. There is a fine line there. I run 4 of those same tires, just painted the ET black. That type of tire tends to wrinkle alot even at 18~20 PSI. I run 18psi rear, and 22-24 front(4x4).

This is the only picture I have of my tires.
