What's the purpose of those stationary burnouts? Is it show or is there a useful purpose?

generate heat in tires.

thing is, after the burnouts from the big boys, it takes so long to back up and then get into pre-stage etc, they must have cooled down a hell of a lot!!

i heard about the theory of burnouts and it seemed it doesn't really generate heat into the tyre as such.

but it does make the top layer become tacky and warm.

the latteral movement of the tyre wall is more suited to generate heat into the tyre for real traction.

how long can a set of top fuel type car tyres last?

Well the real trick here is that when rubber gets hot it gets sticky ! bit like f1 tires etc. The differance between no burn out and a good burn out is measurable in seconds

I think Scott was the one that told me that it also lays down a patch of your own rubber past the start line so that you get better grip. The theory is that your tyres grip better on your rubber.

Perfectly correct assuming

a/ it's not a 4wd (without a 2/4 switch)

b/ it's got enough grunt to break traction on a skicky surface (as oppossed to spin the clutch)

As far as i know Duncan is 100% correct.Hope this theory works for me

I use Mickey Tompson drag tyres and they only require a small burnout to become sticky and not a full on burnout, according to the manufacturers. Drag tyres are available in different compounds too, to suit your type of car.

There is a certain amount of showboating with burnouts of course : 8)

Not that you would catch me doing that of course

No it's a bit of deft left foot braking to lock the front wheels:o

It doesn't do the rear pads any favours though :oops:
