Yeah back in the days of rear wheel drive vehicles that went through snow weighed alot more then the S2000 and if Sports cars are for winter why dont they have Winter Formula 1 racing let Michael Shumacher do best lap times in the Snow you guys are funny S02s in the snow= no traction keep the car in the garage and dont risk driving in the snow you may get in trouble or hurt someone else so dont take the risk if you have another vehicle thats FWD or 4x4 use it and be careful I work in a Emergeny room and accidents are not pretty BE smart

There is a temperature at which the tire compound component will turn sharply harder. In polymer science, this is the glass transition temperature (Tg). A tire is typically a mix of a half dozen rubber constituents, so it's all in the mix.
The temperature of the tire is generally based on the heat gained (by sidewall flex, tread flex, and surface friction) minus heat loss (mostly through convection to the ambient). If you're driving in the rain, slush, or snow, the more significant heat loss is through conduction, which really pulls the temperature down!
Therefore, you can't directly compare the tire compound's Tg to the temperature outside, at least not after the first mile or so.
"All-season" tires have a tread compound that has a low Tg, and therefore will have more predictable behavior under varying temperatures. However, there will be a degree of compromise on ultimate performance of the tire. How well this compromise is minimized is based on a tire manufacturer's tread compound development efforts.
For instance, here's an article from a few years back. This particular tire fits our S2000:
Introducing the AVS dB - the Quietest Ultra-High Performance Tire to Hit the Streets
August 17, 2000 - Yokohama's new AVS dB is making noise in the marketplace because it is so quiet on the street. The AVS dB (Advanced Vehicle System Decibel) is the ultimate high performance tire that meets the demands of today's drivers. By combining outstanding wet traction, ride comfort , low noise levels and all-season traction, Yokohama pushes the limits of current design and technological philosophies and sets the AVS dB apart from any other tire on the market today.
The quietness of the AVS dB is the result of a sharply honed balance among several tread design elements. The tread features tusk grooves that are narrow at their open end to reduce noise levels caused by trapped air. These same tusk grooves are placed at a 20 degree angle which is optimal for breaking up noise patterns and channeling water from under the centre portion of the tread. A subtle wave pattern in the tusk groove walls
prevents distortion of the groove during road contact and minimizes noise caused by escaping, compressed air. Narrow grooves in the shoulder restrict the space required for
airflow noise. Finally, the tread blocks vary in size and position to create a self-canceling effect on the footstep noise that is common among ultra-high performance tires.
Borrowing form the recently introduced AVS Sport, The AVS dB inherits an aggressive, proven tread pattern. The continuous centre tread block of this unique design, maximizes rubber-to-road contact, eliminates tire squirm and reduces noise. This continuous tread block provides a stable base for traction and handling on dry surfaces and reduces noise associated with segmented blocks.
To achieve ride comfort without compromising high performance handling, Yokohama engineers developed an all new casing design to control tire flex. Active Flex Control (AFC) technology allows the AVS dB to change its flexibility as operating conditions change, acting like a soft tire to absorb bumps and reacting like a stiff tire when cornering loads are applied. AFC technology provides greater vertical flexibility allowing the tire to easily absorb shock, creating a smooth ride. As cornering loads increase, the shape and new construction work together to generate increased lateral stiffness, greatly improving steering response and handling capability. The result? Outstanding ride comfort as well as ultra-high performance handling.
A new carbon based compound technology is used to expand the AVS dB's range of operating temperatures. This compound allows the AVBS dB to remain pliable at low temperatures while at the same time generates high grip at high temperatures. The result is all-season grip.
The AVS dB is equipped with a Rim Protector Bar (RPB), built-in wheel protection against potholes and curbs. AVS dB's side wall features a bar of hardened rubber, which delivers the most functional protection available for this class of tire.
High technology belt construction provides shock-absorbing capability but retains rigidity when high lateral loads are applied. New belt cord and specially treated nylon combine to give this performance combination capable of pleasing sports car and sport sedan drivers alike.

I assume you are talking about the S-02.

I have driven my S2000 in snowy conditions only once and it wasn't pretty. It lost traction very easily. If you must drive in these conditions get the proper tires (you are asking for extreme problems with the SO2s) and put a 100 lb. bag of sand in the trunk. Also, remember, you are limited by the low ground clearance and you may damage the under carriage if you hit really snowy conditions.
