awd and warming up tires?

[MikesDSM]

well im 99% sure theres no way of warming up tires on a awd car b4 a race? is there?

 

[markGSX]

Not that I know of, but I don't think that's ever necessary.

 

[MikesDSM]

figured

Not necessary.

I spin hard off the line, and wish there was a way to warm them up, but there really isnt. You can do a launch in the burnout box, but thats likely to do more harm than good, and it wont put enough heat into the tires to make a difference.

If there were almost no other cars at the event, you could wiggle around a little in the staging lanes to try for some heat, but im not sure the track owners would appreciate that.

There's no gain from warming up street tires

 

[Antilles]

I disagree. I see very large traction differences between 40-60* days and 80-100* days.
I can only assume that the temperature of the tires has a great deal to do with this.

On a day that is colder than 30* I cant hook my AWD till 3rd

in formula one they lock up the brakes right before lining up

I've never seen them do that, and it would be a bad idea anyhow. Especially in F1. You cause flatspots that way, and only warm a small part of the tire.
I have seen them do rolling burnouts in formula one.

Heating up a street radial in the burnout box at the track "lowers" the performance of the tires. Slicks, on the other hand, work in the complete opposite manner.

 

[Antilles]

there is such a thing as too hot to be of any benefit, but warming them up does indeed help.

Where hot street tires lose performance is autocrossing or road racing. In that case they can quickly overheat and then just sort of mush.

In F1 they turn off traction control for the run-up lap, are working with pre-heated (180°) tires to start with, run a full lap at speeds over 100, and don't run AWD and haven't since the Ferguson-Jaguars of '62. Cheese and chalk, cheese and chalk.

yeah street tires turn to mush if you heat them up, some could probably benefit from a little bit, but most street tires are just going to lose performance

ive driven a couple friends rwd's and after i do a litlte burnout its a LOT easier to burn them, they turn all nasty and feel greasy

I've watched every F1 race for the past 2 years. They do it, the commentators even talk about it. The lock up is very brief so flat spots don't form.

If you do a practice launch that spins the fornts alot it heats up the viscous coupling and grabs much harder on the next launch.

Ive personally never benefited from burning my street tires on my camaro. It makes my launches worse so I dont do it.
