Weird question..

[GothicKidd]

Okay.. This is a weird question but...
What makes 'burnout marks stay for a long time'
Ive seen a few marks around town... Some that have been there for a while and some new.... but Ive seen a couple.. and next day they've faded.. So im wondering what makes them stay longer? I know some roads are used more than others but yeah...
I know its a weird question.. but im curious..

obviously the ones that last for a while were good burnouts lol more smoke more rubber left on the road, funny thing when i was a litte kid i used to think the single line burnouts (single peggers) were burnouts done by a motorbike lol

Different tyres, Silica, everything accounts to it. I know highway Max remoulds do a deep black mark

Hmm fair enough haha.. I never noticed anything to do with cars till I was like 14 or so.. never noticed black marks.. or knew what they were till I got my License.. :P

I thought different tyres made a different impact.. :\ Cuz I went out tonight and left black marks in the wet.. but If I had did that with a different tyre I wouldnt of left anything.. :\

the thing that makes them stay is called 'heat'. the idea is you want a tyre that provides the most friction with the road surface. rubbing the two compounds together creates heat which in turn starts to melt the outside layer of tyre and the top layer of bitumen. as your wheel spins it scatters molten rubber/tar and the hotter it is the easier it is to heat the next piece of road you drive over.

you will find that the majority of long skids are really just heating the tyres up enough over a patch of 50mm and the rest is just molten tyre and bitumen marking a road that has been weathered.

thats why burnouts on fresh roads are not very noticable. because the surface of the road is black and fresh. older roads go a slightly grey colour as the sun dries them out, and what you are doing is just laying a fresh bit over the top of it, which you picked up at the start of the burnout.

having said all that, what you are doing essentially is digging a 230mmx200mm pot hole in the road which makes it worse for evey other driver. not to mention wearing out every component in your drivetrain, and also scattering molten tar and rubber over the rear of your car.

I was not expecting a comment like that! but that makes sense! ^_^
Thanks for that Ari, Much appreciated ;P

well, im not gonna pretend like i have never done one...


or plan to do one in the not-too-distant-future

Indeed they do


Generally soft as possible, and as much power as possible determines how long they stay.... ari pretty much summed it up lol

[The pig]

Good question, maybe tyre type eg soft or hard compound, tyre pressure, road surface etc and trying to creep with the brakes, and a healthy car alround (just incase). There was one near my place years ago and it did a lap around a group of shops it was there for f###### years.

Apparently a lot of guys at the Summer nats use 4 wd tyres soaked in diesel for a while first WTF.

[CommodoreVS]

From what I heard soaking tires in diesel, it makes them smoke up better in a burnout, hence why they ignite/catch on fire..

[GRPABT1]

Soaked tyres are banned in competition. Heat is the answer and the faster you spin the wheels the quicker you will create it. This is why burnout cars run highway diff gear with big Hp to turn them. Fully hectic 1st gear skids are not going to make alot of smoke or leave lasting marks.

got to do with tyres and time..
