Mr Shiftright,
 
If it is on the Prius chat then there probably is a problem. But with high mileage , hard skinny tires no car would go well in the snow.
 
The Prius chat people that are having problems, probably haven't put on snow tires? Are they having problems in snow with snow tires ?
 
Cheers,

I do agree with the 50/50 weight bias. I live on the Tug Hill Plateau near a place that frequently makes the national news for most snowfall. I'm not faithfull to any one brand of tire. I usually by the lest expensive snowtires and have them studded, all four of them. With this setup you can drive anything in the snow. To be honest, one of the best cars I ever had for snow driving was a 1983 Chevy Camaro with a 6 cylinder. I wouldn't have dared try it with the 8 cylinder. Weight distribution is important but if you've got too much tork it won't get out of it's own way on the ice.
I'm glad these forums exist because I was seriously thinking about buying a Prius. My mother had two Honda Insights and she loved them. With the problems I've read about in here about the Prius I think I'm going to go with a more conventional vehicle. Gas mileage is important but I need something that I or my amatuer mechanic can do some of the repairs to.
Hopefully Toyota will continue to work out the bugs. The brake problems I've read about were the deal-breaker.

Well what they say over there is that the car simply won't move if it gets into a slippery snow condition...it just sits there and does nothing. So at that point, if they are right, then tires are irrelevant, once they've given up their grip and the computer takes over.
 
Supposedly this traction control system does not work the same as on regular cars. I'm just passing on second-hand info, I don't have a clue. I would like to try a Prius in the snow however to see what's what and if driver skills really is the problem or not.

Your post is absolutely correct. The car just sits there and does nothing and has nothing to do with driver skills. The traction control IS different from other cars due to the fact that its primary purpose is to protect the electric motor from over reving and possible burnout.I have been through 3 upstate new york winters living with this. I do not plan on another. I hope this is good advice for those considering a Prius.

Prius in the snow by grandtotal
Sep 13, 2006 (8:19 am)
I rented a (2005) Prius while on vacation in Arizona this year. While visiting the Grand Canyon I experienced difficult snow and ice conditions. There were many vehicles (mostly SUVs, go figure) in ditches. During that whole day I only experienced one problem and that was more engine braking than I wanted while creeping down an icy hill. What I found was that the front wheels were rotating and skidding at the same time because of engine braking, that is to say the indicated speed was about 10MPH but I was descending the hill faster than that. In the end I had to select neutral so that I could achieve balanced braking from all four wheels.

Good idea that's how I solved it also. I moved to Houston.
 
Reading between the lines, I would say that the HSD system has a snow/ice traction control bug.
 
And another commnet the 50/50 weight is being touted for the wrong reasons. 50/50 is considered ideal for a true sports car in good weather conditions. 50% of the weight on the RWD and 50% on the steering.
 
For traction you want more on the drive wheeels. Actuallly most front wheel drive are 60% on front wheels . However, this does increase wear on those wheels and makes steering heavier. That is why there is so much to od about i4 versus V6 in handling. with I$ theres is close to 50/50% weight distirbutuion. The auto manufacturers changes nothing add the additional weight of the v6 and the steering is heavier.
 
If you are wealthy , I understand the ideal snow car is a Carrera 4 with Blizzacks on all four wheels.
 
Studded snow tires last resort, unless wehater conditions really really bad. The studs tearr up everything have bad handling excpet on ice and return poor mileage. Almost as bad as snow chains. Glad I don't deal with either naymore.

"I rented a (2005) Prius while on vacation in Arizona this year. While visiting the Grand Canyon I experienced difficult snow and ice conditions."
 
The problem arises when the Prius is stuck in the snow. On conventional cars, one can "rock" the vehicle back and forth to get the car moving again. The 2004-2005 Prius (at least) would not allow the wheels to spin in this situation, resulting in the car just sitting there, dead as a doornail. There was nothing mechanically wrong - but the computer would not let the driver engage the wheels.
 
The situation would not come up unless the Prius got stuck. You simply never encountered the proper conditions.
 
Some people are posting that the 2006 Prius corrects this problem, but so for no one has posted any personal experiences. Perhaps next winter...

Rocking, IMO, has never been the "best" way of getting out. Placing sand, cardboard or a wood plank has always worked best, and would for the Prius.
 
Seems most would prefer not getting out, to actually getting themselves unstuck!

Your are absolutely right Terry and you can accomplish this is you plan ahaead and carry the sand , cardboard, or wood plank with you.
 
But what hapens if you don't have any of those items on board, either a freak or unexpected ice/storm comes up or you just didn't plan ahead and put the supplies in your vehicle. What do you do?
 
That is why you rock a card back and forth!
 
Might be too far or too cold to walk!
 
good luck,

When I lived in big snow areas, I certainly did always have a couple of 2x6's about three feet long, along with a knocked-down cardboard box or two, in my trunk. Even if only for putting on chains, those boxes often came in handy!
 
I also always keep, even in So California, a camp shovel, which I could always use to dig down for dirt, if really stuck.
 
I mean, just how much space do those take?
