Driving a Tesla Model S on Winter Tires

Published

on

Winter Wheels InstalledThe snow has already begun to fall here in New England which means that my new set of Tesla winter wheels and tires will be put to good use very soon.

Tesla Model S Tire Cheat SheetIn preparing my Model S for the winter, I also put together a quick Tesla Model S Tire Cheat Sheet which outlines where the jack points reside on the car, recommended tire pressures as well as the torque rating for the lug nuts. The cheat sheet was given to my tire guy which hopefully served as a good reference point.

The installation was simple and quick. The tire place used two heavy duty hand jacks to lift the entire left side of the car, take the tires off, put on the new ones and then repeat on the right side. They used an air wrench to take the nuts off and put them back on before lowering each side.

The air wrench was limited to 100 lbs/ft torque and they hand tightened to the recommend 129 lbs/ft torque after all four wheels were on and the car was back on the ground. DIY’ers can follow along through this great video that describes the entire wheel swap and TPMS reset process.

Driving on Winter Tires

The Nokian Hakkapeliitta R2 winter tires have provided a different type of driving experience all together. The tires feel “squishy” and definitely not as tight on the road as it does with the factory tires – expected. Everything I read about the Nokians indicated that I would expect poor traction for the first few hundred miles (300 miles is a good rule of thumb) so I decided to play it extra safe and avoid any type of quick acceleration and quick turning during the beginning phase. There’s no question that the winter tires were more slippery during the initial “break-in period”, but after surpassing the 300 mile-market point, I started pushing them a bit harder to see how they behave on both wet and dry conditions.

Some Tesla Model S owners have had concerns with tire slippage during acceleration on dry pavement as seen in the video below.

Summary

Although I didn’t experience tire slippage during hard acceleration and quick deceleration on the Nokians, extra caution still needs to be had when driving your Tesla on winter tires especially when there’s no snow left on the ground, either because it got cleared or melted away.

Overall I’ve been happy with the new Nokian winter tires and I love the look of my new TST wheels (my dedicated winter wheels) . I’m looking forward to driving the Model S once there’s more snow, ice and slush on the ground. This is where the Nokian winter tires should really begin to shine, but more importantly carry me through a harsh New England winter in one piece.

Pirelli unveils its first-ever replacement tire for EVs: the All Season Plus with Elect marking

Pirelli, the Italian tire maker, announced today the introduction in North America of its first-ever replacement tire for electric vehicles: the P Zero All Season Plus with Elect Marking.

The Elect marking on Pirelli’s tires indicates several distinct advantages. First, the tire has low rolling resistance, which increases driving range and reduces energy consumption, making stops at electric vehicle chargers less frequent. When coupled with a high-range vehicle, like the Lucid Air Dream Edition or Tesla Model S All-Wheel Drive, the Pirelli Elect series decreases road contact, making the vehicles more efficient. When non-Elect P Zero All Season Plus tires have been fitted on vehicles, the Pirelli product has shown a reduction of rolling resistance by 15 percent, translating to direct improvement of the EV battery life cycle.

One of the most important and distinct advantages is also the reduction of road noise, creating a more peaceful a quiet experience in the EV’s cabin. In electric vehicles, road noise is more noticeable as the lack of a loud combustion engine, which drowns out these noises in a gas-powered car, provides more noise within the cabin. This was a main focus of Tesla for several years, as many consumers had stated road noise had gone to nearly intolerable levels. Tesla eventually worked with tire manufacturers for insulated rubber and made changes with its build processes to alleviate some of the cabin noise complaints.

Road noise won’t be a concern for those who utilize the Pirelli All Season Plus, as it features the company’s PNCS, or “Pirelli Noise Cancelling System.” Pirelli developed this technology to reduce interior noise thanks to a sound-absorbing material applied to the inside of the circumferential wall. It offers improved driving comfort, which is another feature appreciated by EV drivers. Tires equipped with PNCS have shown a 5 percent reduction in cabin noise versus the leading OEM competitor.

Another incredible advantage of Pirelli’s Elect tires is the immediate grip it provides for EVs, helping support the notoriously fast acceleration of electric powertrains. Along with the traction control and launch grip advantages, Pirelli’s tires support the weight of a battery-powered vehicle, the company said.

Pirelli continues to develop new tires and technology for EVs, especially as the automotive industry continues to show a massive transition to more sustainable powertrains. Pirelli was the first tire manufacturer to homologate a dedicated technology for EVs. It also has the highest number of homologations of tires for electric vehicles.

“Developing a tire specifically for electric vehicles requires a number of considerations you do not encounter when working with internal combustion engines,” Ian Coke, Chief Technical Officer at Pirelli North America, said. “Electric vehicles are heavier, have more powerful and faster acceleration off the line, and require lower rolling resistance.”

Pirelli developed a new compound formulation that increases abrasion resistance of the tire, which compensates for the high torque and increased weight, which EVs both have. The tire is built to offer “long-lasting performance in every condition,” the company said.

The new P Zero All Season Plus Elect will fit some of the most popular EV high-performance models and will be available from 18 to 20 inches. In addition to the clear EV vehicle benefits, the new P Zero All Season Plus Elect comes with a 50,000-mile limited treadwear warranty.

Tesla launches Model 3 Track Package with ‘Zero-G’ wheels and race-focused brake mods

Published

on

By

Tesla has launched a new Model 3 Track Package for racing enthusiasts looking to maximize track performance of their all-electric sedan with Zero-G Performance wheels and race-focused brake and tire modifications.

The new performance package is being offered for the Tesla Model 3 Performance variant at $5,500 and includes stickier Michelin Pilot Sport Cup 2 tires that are popular among track junkies, high-performance brake pads and racing brake fluid.

“Optimize the track performance of your Performance Upgrade Model 3. Track Package is a complete hardware package designed to give you maximum cornering force, braking performance and high-speed stability for the best lap times,” reads the description on Tesla’s online Shop for the upgrade.

Tesla Model 3 Track Package Includes:

  • 4 x 20″ X 9″ Zero-G Performance wheels
  • 4 x Tesla logo center caps
  • 20 x Lug nut covers
  • 4 x 245/35ZR20 XL Michelin Pilot Sport Cup 2 tires
  • 4 x tire pressure sensors
  • 1 x front and rear high-performance brake pads
  • 1 x track-focused brake fluid

Included in the Model 3 track package are a set of 20-inch diameter “Zero-G Performance Wheels” in a “square set up”, whereby all four wheels and tires are of equal size. The upgraded Zero-G wheels in a 20″ x 9″ set up are 0.5 inches wider than the factory 20″ x 8.5″ Model 3 Sport Wheels. Combined with wider and stickier rubber from the Michelin Pilot Sport Cup 2 tires, drivers are able to negotiate more aggressive cornering speeds in their Model 3 Performance as well as higher entry speeds.

While Tesla’s single-pedal driving capability through regenerative braking means that a driver rarely needs to use the brakes, the demands of track driving at high speeds into turns on a race circuit require the heavy use of brakes, often leading to brake fade due to higher brake temperatures.

Tesla’s Model 3 Track Package includes high-performance front and rear brake pads that are designed to withstand more aggressive braking and higher temperatures, paired with Tesla-branded, track-focused brake fluid.

Model 3 Performance owners looking to purchase the $5,500 track package can coordinate shipping and installation with their local Tesla Service Center.

Shipments for the Model 3 Performance Track Pack is expected to begin in April 2020.

Tesla adds Model 3 snow chains for 20″ Performance wheels to online store

Published

on

Tesla Model 3 snow chains for 20″ Performance wheels have been added to the company’s online store.

The Maggi Trak Sport 214 snow chain is a unique type of self-adjusting and easy-to-install chain that utilizes four clamps and one fixing point for installation. Rather than wrapping the chains around the inner portion of the tire, the outer wheel side of the drive wheels is used as the single fixing point over complex inner side attachments. Excellent traction and durability in snowy conditions are to be expected from the aftermarket addition. Previously, snow chains were only available for Model 3 with 19″ wheels in a dual motor and rear-wheel drive configuration and were produced by a different manufacturer.

Tesla’s store also notes that the Maggi Trak Sport chains are only approved for Model 3 Performance 20” wheels and Tesla-approved 235/35R20 tires. Additionally, they should only be installed on the rear wheels. For $290, the snow chain package includes a nylon protective bag, one pair of chains, and an installation guide, and delivery is anticipated to take 2-3 weeks.

According to the manufacturer, the self-adjusting nature of the Maggi Trek snow chains ensures a perfect grip between the chain and the tire tread. The gripping unit design has a smaller profile that won’t compromise the minimal space between the outer tire and inner wheel well, resulting in a safe and quiet drive. The Maggi Trak Sport snow chain system is also available for the Model S.

Watch the video below for how to install the Model 3 AWD Maggi trek snow chains, as demonstrated on a Model S:
