| Post subject: | Over heating tyres |
Last race meeting my car had really bad handling and any changes that I made didn't help. The car would over steer off power and sometimes on power, a few of the other drivers had a few problems with handling issues as well. The temp of the day was over 35 degrees C and a few Brushless sytems were shutting down due to heat. What things could I do to keep the tyres from over heating? Here's my setup http://www.teamxray.com/xforum/xform/in ... tup=t1fk05 |

Make small holes in the rims with a body reamer, this will make the tire run cooler. Start with 2 and then make 4 if needed. |

I'm going to try running 3 degrees anti-squat and run white springs on the rear, I needed to stiffen the rear because when running a mod the rear would to bottom out and make the car over steer. Would anti-squat stop this from happening? I will also try running 40's instead of 36's and will drill more holes and make the exsisting holes bigger. Thanks for your input. |

anti squat could help in low grip conditions. When accelarating (out a corner) the car will be more stable, so you can go faster out. The disadvantage is that the car, going into corners at a high speed will become unstable at a sertain point with anti squat. But....it's worth trying. |

Personally I feel no airgap is bad, but too much is often worse. The reason people recommend a big airgap is that it allows the tyre to move around a bit resulting in less stress being put on the rubber itself. Less stress means less heat build-up (the key is to keep the rubber "cool"). However air heats up very fast and is a good heat conductor. If you have airholes in the wheels that are large enough to continuously refresh the air inside then this is less of a problem but if the air inside stays hot then the rubber will heat up anyway. That is why I tend to run softer inserts (mostly medium-soft) but with only a small airgap. The soft insert allows the tyre to move just like a big airgap does, reducing heat build up in the rubber directly. By running less airgap I prevent heat build-up in the air inside (the rubber insert heats up much slower) and thus further reduce the heat. To keep the car rolling I normally combine this with hard wheels. |
