I get my liscense in october, i live in massachusettes.
[sarcasm] this is going to be one fun winter! [/sarcasm]
Put some weights in the back, get some traction. cinderblocks work too.

A guy near me puts 50lb bag of sand (or two) with some good winter tires and he says it drives great. I will not be driving my 240 when it snowing however as even if you can drive others can't and could still mess it up.

240sx sucks in snow in hilly areas, you'll get stuck sideways on step inclines. wheels will push the car and the car will go sideways on a really step incline. flat land is ok

Add some weight at the back and deflate psi as BigVinnie and daves240sx07 has suggested you will be fine.

But if you change to sr20det one day, forget it. Its brutal then.

put weight in back - YES
Deflate psi- NO
This is one of the most common mis-conceptions that people have.

I've lived in new england my whole life, and my family generations before.

We get several big snow-storms a year here.
here's how it works:

When you deflate the tire, the pressure and weight from the car is forced towards the edges of the rims. Therefore, the outer edges of the tires exert more pressure than the middle of the tires. An are of low pressure, from lack of PSI causes the middle of the tire to form an arc. When proper PSI is put into a tire, the force is exerted equally, and more of the tire is in contact with the ground.

When more rubber is on the ground, there is more traction. The low PSI work in the sand, because the sand lets you sink, but it eventually compacts on itself and the tires "pankake" over the sand. However, in the snow, it compacts, but becomes slippery, just like in water, when its slippery, the more rubber touching and exerting force, the easier it will be to regain traction.

Thats not how it works in the snow. When you deflate the tires the purpose is to allow more rubber surface to grip the road. The walls of the tires become pudgy and cover more surface area. When you deflate the front tires especially it helps your steering, the walls of the tires have more surface area to cover. I learned that on the discovery channel a few years back, when they took a Toyota Land cruiser out to greenland.
I've been doing it every year since, everytime I go to the mountains to go snowboarding...

I've been on Icy conditions with properlly flatted tires, you can turn left or right, even hit the brakes, the car will usually glide straight. Thats why you deflate.......

HAHA microsoft paint blows, but this is how deflating works in the snow...

In my experience, I keep the pressure lower in the summer, and higher in the winter. Ever tried walking on ice with snowshoes? You'll get more surface area and no traction!

I also leave 4 x 25lb bags of salt in the trunk, and use 4 season tires that are LESS than 2 years old, after that, get some good winter tires.

On my other cars, I have 15 inch wide rear tires. There ain't no way I'd be ever able to drive that in the snow....

The whole idea is to cut throw t he snow to git to the ground where the tracktion is. So skinny tires work beter in the snow then fat ones. I saw the same thing on dicover with that toyota. They where running on ice and snow with no ground to fall to. so n that cause you would want big fat tires to pack the snow for tracktion. But we live in the real world where the roads are plowed and salted or sanded and people have driven on it you want to see the ground. On ice you want studded tiers or chains. I just bought a 93 escort for 500. Why. So when I hit that snow bank or go off the road I can say o well. If I wrecked my 240 I would be a little more upset. I like to have fun in the snow but there are bigger risk when dealing with snow and ice. In my last post i said better car. I meant a car you can dent up or more. The 240 are a better car.

holy crap... what cars have those tires?!

In the snow, the lower psi helps the tire have more surface on the ground... inflating it makes the tire push and compact the snow instantly, so you slide everywhere... deflating allows the tire to give a little and form around the snow and have more surface area to grip...

Cape, the inflated/deflated tire diagram you have is true, but in warn weather... unless they keep your roads super duper salted and cindered.

BigV... where do you board at?

What kind of cars have 15" wide rear tires?

I have a 1970 Dodge Challenger and a 1973 Plymouth Roadrunner. The reason behind the wide tires is due to the high HP generated by the engine would make the tires slip more than anything else on fast take-off's. Now, that being said, it only works on dry pavement. I couldn't even think of driving these cars in the winter let alone with those tires on.....

The logic of wide tires offering more traction is only valid on dry pavements. There's another little factor called friction coeeficient that comes into play. You ABSOLUTELY need to increase tire pressure in the winter to reduce the surface area and increase the PSI ratio (car's weight : total contact surface on ground).

If you snowboard, you'll understand that the width of your board has been engineered to give you the maximum acceleration, best control possible. If you board was only 4" wide, it would sink in the snow, but although control would increase, speed would be reduced. If it was 24" wide, you would be ableto go at much higher speed, but would have much less control.

If you're a hockey player, then you know why they use skates, and not snowshoes.....

Try it out this winter in a parking lot after a snowstorm. I know that I'm 100% correct on this one. Trust me!

Go to a web site for ice and snow racing and you will see they use really skinny tires
