I live in Northern Illinois, during winter snow conditions Red Light "Snow Drag Races" are an integral part of driving around here in the snow belt, before you complain about illegal and dangerous street drag racing, you should know that these so called "races" are actually very safe and usually undetectable by anyone watching, they last only a short distance and (usually) ends before any speed limits are violated. Because of the limited traction these impromptu "acceleration tests" look just like any other two cars getting up to speed after the lights turn green. You would think that all wheel drive would be the deciding factor in one of these "tests", but while AWD is needed, it is the type of tires used that is the most important ingredient. I have found the Blizzak ice tires, and they must be the softest "Multi-Cell" formulation only available for lower speed rated vehicles and also only low weight non SUV types get the super soft compound. However, when you are driving a car that can run on these specialized winter tires I have never been bested while accelerating in low traction conditions, so far I have won 100% of the time, no matter the competition, AWD Jeeps, with or without giant Mudder tires, big wheel trucks, Police cars. (Yes, I do regularly beat cop cars, it's not illegal to accelerate quickly up to almost the speed limit in the snow.), It seems that most people go with all season tires, even if they do get winter only tires, they (so far), cannot out accelerate my car equipped with the "low speed" Blizzaks. I do not think the Multi-Cell formulation can be used on heavy or high performance cars because the compound is too soft and they would probably get too soft and start to "Chunk" off pieces at higher speeds, so you probably won't be able to get these for a Model S or X. You probably are thinking that I feel that I would win against an AWD tesla, but I do not think that, the weight and electronic traction control on a Tesla would probably easily out accelerate my car, I am pretty sure of that. I wanted to share my personal experiences with snow and ice traction, and winter ice tires on my car, (2010 WRX), I have found that running Blizzaks gives my vehicle maximum traction possible. Blizzak tires are available for SUVs and heavy, high performance cars, but not with Multi-Cell technology. They behave a little like foam rubber, if you were to wrap foam rubber sheeting around your shoes, you could walk on black ice with excellent traction, that's the basic mechanism behind these tires, they really dig in. Only the Blizzak WS60's features Tube Multicell TM Compound and Nano Pro-tech technology developed to deliver snow and ice performance without studs. All the others are regular snow tires.
From the official Blizzak web site;
Multi-Cell compound removes a thin layer of surface water to improve grip using millions of microscopic pores. This compound also allows the tire to remain flexible in freezing temperatures, improving traction and available grip. The high Sipe density of our snow tires improves traction in the wet, snow, and ice by increasing the number of biting edges.
Snow Tires Winter Tires: Bridgestone Blizzak | Bridgestone Tires
I am not doing a commercial for Bridgestone Tires, they really are that much better compared to other brands. If Blizzaks with Multi-Cell technology could be formulated that could be run on AWD Teslas, that would be a way to increase Tesla's already amazing winter traction even more, perhaps some day this will happen.
