Best way to launch on Kumhos? Tire pressure?

[ViperBing]

I was wondering what kind of tire pressure people run in their Kumhos when running the 1/4 mile?

What RPM's do you launch at?

It depends on track conditions, I would start at 2500 and work from there. make sure they are warmed up .

How long of a burnout?

 

[PRVT JET]

3 or 4 seconds should be good, Practice launch right before you stage.

I'd get something other than kumho's.. they have turned greasy on me once they heat up.

I agree with Roadkill, they are not a drag tire. Any tire will work with good track prep, don't confuse Kumhos on a prepped track as the tire providing the traction.

I have run kumhos at around 20 to 22 psi, 3 to 4 sec burnout, depends on the track though, i have run 2.0 60' launching at 2500 rpm at some tracks and, i have run 1.7 60' launching at 4000 rpm, i do not suggest launching at 4000 unless car is hooking up, that particular day i was not spinning at all and the car was bogging down off the line.
