Default How do you "preserve tires" and still be fast

In regards to racing (both endurance road and rally), what are the professionals doing when they say they are "preserving" or "going easy" on the tires?

Obviously they don't want to slow down, this is a race. On the road, they obviously weren't trying to slide. In rally, the road is the road.

What are they changing in the way they drive that is a "preserving tire" strategy?

It's all about not going as fast as you can. Not diving as as deep into the corner before getting on the brakes, not carrying quite as much speed through the corners, not spinning tires on corner exit.
Doing everything just that little bit less on the edge. You are going slower, but not SLOW.
Also known as driving 8-9/10ths instead of all out.

Dont slide them.

also included in don't lock up/spin them.

You can still drive at the limit and preserve tires. Watch video of Jensen Button, he's awesome at it.

Smooth driving. Don't bomb into corners and use the turn/understeer to scrub off speed, don't wail it on the way out, press on the brakes instead of slamming them and working the ABS...

Proper tire pressure, rotation. And alignment but that goes with tire care in general.

I'd say Dario Franchitti is the best at it. He's also awesome at saving fuel while being fast, which is the same thing, really.

Yes I stated the obvious about tires but does all that not take part in preserving your tires. Reguardless of how smooth you drive if you dont use incorrect tire pressure etc. they wont last as along

Tire pressure is more of a traction element on the track... sure you can't run them at 2 psi, but tire pressure on the track has more to do with how the car handles than "wear". Most track wear characteristics come from overheating, sliding, and spinning them.

Not so much. If you're trying to save fuel, you want to carry as much speed as possible on corner entry and through the middle of the corner at the potential expense of lateral tire wear. Throttle on is the same for tire wear and savign fuel, but corner entry to mid corner is not.

As mentioned earlier, preserving tires is mostly about driving at 8-9/10ths and minimizing the amount of tire slip and scrub. In cars with more grip than power (Miata, for example), from the time you start applying maintanenece throttle you want to minimize tire slip and scrub anyways to maintain speed, and it does help tire wear.

From the driving I've done, in general, I am harder on brakes and fuel and easier on tires than most people, but it's an easy transition for me if I need to either be easy on the brakes or conserve fuel...it just means I slow down a bit compared to an all-out flying lap.

One way to preserve tires in stage rally is to pick one step harder compound. You trade off a bit of grip in return for tread blocks staying sharper a bit longer.

Another way to preserve tires in stage rally sounds simple but can be surprisingly hard to accomplish...."don't hit stuff." Some drivers' insistence on cutting corners often adds up to blown tires (or corners getting ripped off the car).

Howbout Shaving them?...Maybe that's for track dedicated tires and not rally tires.

Monitor the tire temperature and make sure you are not higher than the recommendation. This is of course tied with driving smoothly and not scrubbing.

I like even heating across the whole tire at about 3/4 the max rate. Good wear, great grip.
