Snow tires?

Couple of comments on tires and electronic systems Tires work best in the temp range they are designed to work in, a tire with a wide range of ability's all season make compromises in the working ability of the tire. A tire like a snow tire will give you the best possible control in the conditions. Traction control can be done by reducing the engine firing dropping out cylinders from firing this reduces wheelspin with out putting dynamic forces on the vehicle by using brakes to stop wheelspin. I know the problems with wheel speed sensors and most of the systems are dependent on WS to control ABS or traction control or driver assist electronics, where some of the more high tech systems use yaw and pitch along with accelerometers and pressure sensors & WS to keep vehicle pointed the way the factory wants. Also think there will be more incidents like the runaway toyotas that lead toward deep in the electronic circuitry problems. |

Cellmate in the clink, eh, Horvie? |

I drive a truck so I don't know if they're appropriate for a vehicle like yours. But for years I've bought Cooper Tires. I rotate them every other oil change and get 50K plus. I had them on the pigovan and two trucks since. They make a pretty wide range from 4 season to HD mud and snow. When my tires wear out I just buy a new van. *A van is the only vehicle a skier should consider because you can keep your skis inside, clean and dry while driving to the ski resort. Vote for Palin-Brown in 2012. *Repeal the nightmares. This signature is now the ultimate power in the universe If you had used Turtle Wax on your skis, they would be clean and dry on a roof rack while driving to the resort.- Hide quoted text - This lying, stalking coward has me killfiled, but not Horvath. Despite the sick jokes about raping kids, despite the gross defamations, despite the death threats. Says all anyone needs to know about Richard Walsh. |

Sometimes chains AND 4x4. Going up to Mt Baker once with chains on my RWD van, a 4WD ahead of me couldn't stay on the road. He kept sliding over against the bank on the side. I had no trouble. |

I once made it up to Courchevel in heavy snow in a rented Renault Espace without chains (though I had them in the back), overtaking several vehicles en route, some with chains on. A lot of it is down to experience and technique and some luck in encountering moving obstructions where they can be passed |

A tire like a snow tire will give you the best possible control in the conditions. Traction control can be done by reducing the engine firing dropping out cylinders from firing this reduces wheelspin with out putting dynamic forces on the vehicle by using brakes to stop wheelspin. Turns out my 2002 Outback H6 3.0 has both of these: VTD AWD (variable torque distribution). New in 2001, VTD transfers powers front to back electronically. The power split is 45/55 front/rear and the rear wheel bias is designed for a more luxury car feel as opposed to the front bias of the Active AWD system. Usually 45/55 front to back split but that varies according to wheel slippage. VDC system is the top of the line system used on certain models and is also the name of an Outback Limited model. New is 2001. VDC is Vehicle Dynamics Control VDC is composed of 2 main systems: VTD plus VDC full time 4 wheel traction and engine management. VDC is traction control that senses vehicle direction and uses brake, throttle and engine management to help maintain stability. The components of the VDC system a all wheel drive using the VTD system (see above). When the wheels are spinning without traction or the vehicle is not going in the direction it is being steered, the VDC system kicks in. Direction: uses brakes to slow down wheels to reduce spin and help control vehicle direction. Skidding: yaw and steering wheel sensors use brakes to slow down spinning wheels and re-direct power to the wheel(s) with the best traction to re-gain control. Engine power use engine output to slow spinning by reducing spark to cylinders to cut back power and help re-gain control. Who knew ? |

You can picture the typical driver it NO GO "more gas" more wheelspin so car puts on more brake and driver puts on more gas, the cycle continues it is like having a discussion with Itchy it goes nowhere. I am looking at few models of subaru to run in a ice racing series in upstate NY, need to figure out the best one and which ecu is hackable. |

Try a google on "subaru dune buggy" to see what the sand drivers are doing. It might be useful for ice racing. |
