Default Rubber tyres and track conditions.

Upon questioning why I destroy MuchMore 36V's in two runs but don't have the same issue with 32V's a friend told me real race cars have a problem of the same nature. I was informed that if tyres can't or don't get to the right operating tempature that they will "cold" shred.
After this it made me wunder, how do you choose the right tyre for the day? I understand car setup is a BIG factor in what choose, but how do you pick what to start with at a new track that your car isn't fine tuned to?

Post your theory's and opinions.

Cool weather, I'll start with 28-32s.

Warm, pretty much always 32s.

HOT, 32-40.

An idea of what you mean by cool, warm and hot would be good.
Here in Las Vegas, our cool in winter is probably close to some of your summer warms.

The old Take-off tires used to come with a temperature chart which directly related compounds to weather, ie: temperature.
That is track temperature!

But one thing to remember also aswell as rubber compound being suitable for the temp of the track is that you can run your car on a grade of tire meant for a hotter track but run them with a harder insert to generate the temperature needed. (Avoiding the "Cold scrub wear you mentioned!)
You need to open the breether hole too when doing this and its also very easy to overheat your tires when you run with very hard inserts. But if you get the combination right and your able to run with very hard inserts without overheating your chosen compound of tire you will have imence grip, low wear and no overheating of tires!
....(Car set-up permitting of course )

So enjoying building cars I sometimes forget to save some "man-time" to race them!?

Click here for "Rubber Tires for Dummies" Dated, but it does explain everything about wheels, inserts, and tires....and which to choose for which condition.
