The Ecsta Sport A/S is Kumho's Ultra High Performance All-Season tire developed for the drivers of sporty coupes, sports cars and performance sedans who want satisfying driving dynamics without giving up a quiet, comfortable ride. Designed to be proficient in the rain, while still combining the responsive handling and high-speed traction expected of a year-round performance tire, the Ecsta Sport A/S can be used in dry, wet and wintry conditions, even in light snow.
The high-grip resin compound of the Ecsta Sport A/S uses a performance-focused mix of silica and polymers to improve dry grip, handling, and wear life, which is then molded into an asymmetric tread pattern optimized for driver comfort and control. The outside shoulders has been stiffened and strengthened to help resist deformation during cornering and aggressive driving. Rounded block edges disperse impacts from uneven roads, and K-Noise Defender technology inside the grooves uses airflow-disrupting dimples to minimize noise and enhance comfort. The high silica content in the compound improves wet traction, and four wide, circumferential grooves and open shoulder slots help evacuate water to increase hydroplaning resistance. Zig-zag grooves offer grip in snowy conditions, and 3-D interlocking sipes provide the biting edges needed for traction in snow and on ice while minimizing tread block movement.
Utilizing two polyester plies for the casing helps the Ecsta Sport A/S balance comfort and durability, and the two wide, steel belts are reinforced by a single, polyamide cap ply that aids steering response and provides high-speed capability.

Are EV-Specific Tires Better than Popular Non-EV Tires? – 2025 Test 1 (34:07)
In the first test of 2025, we run it back with EV vs non-EV tires with an eleven-tire, five-category grouping. Using our pair of Teslas, we delve into efficiency, road characteristics, wet and dry handling/braking, and of course, the overall rankings when combined! Including a final chart with tires from 2024 added! Sit back, relax, and enjoy the first test of 2025!
Feedback consistently shows the Bridgestone Blizzak LM005 delivers excellent winter traction, with snow and deep snow performance scoring 9-10 consistently. Ice traction earns mostly 7-10 ratings, though a few users report challenges on sheer ice. Wet traction and hydroplaning resistance are strong (7-10), while dry handling receives praise for stability and responsiveness (7-10). Comfort and noise levels are generally well-regarded (7-10), with some noting minor road noise. Treadwear scores vary widely (0-10), with multiple users citing premature wear as a concern. Winter-focused drivers highlight its confidence-inspiring grip, but tread longevity may disappoint those expecting extended seasonal use.

...Initially, they delivered everything I expected from a premium winter tire - excellent traction on snow and ice, a smooth and quiet ride, and solid handling in wet and slushy conditions...
I am base in Utah and do a lot of driving to ski - early mornings and in the evenings - generally when road conditions are not ideal. I had high hopes for the Bridgestone Blizzak tires when I first bought them. Initially, they delivered everything I expected from a premium winter tire — excellent traction on snow and ice, a smooth and quiet ride, and solid handling in wet and slushy conditions. I felt confident driving in harsh winter weather, and they performed exceptionally well for the first couple of months.
However, after just around 5,000 miles, I noticed a significant decline in performance. The tread wore down much faster than I anticipated, and the grip on snow and ice wasn’t nearly as reliable as it was initially.
If you’re looking for short-term winter performance, the Blizzaks are fantastic. But if durability and longevity are important, you might want to explore other options. I wish they had lasted longer because they performed so well at the start, but the rapid wear makes them hard to justify for the cost.

...Without these tires my Dodge Challenger R/T Scat Pack Widebody would be parked during icy and snowy weather, but not anymore!...
I am extremely happy with the winter performance of the Bridgestone Blizzak LM005 285/40R20 tires which are mounted on aftermarket 20 x 10.5 wheels with a -9 mm offset. Without these tires my Dodge Challenger R/T Scat Pack Widebody would be parked during icy and snowy weather, but not anymore!
My comparison is the night-and-day difference in performance between these Blizzaks and the 305/35R20 Pirelli P Zero or Cooper Zeon RS3-G1 All Seasons which were or are currently mounted on the OEM 20 x 11.0 wheels.

...The Blizzak is the best winter tire I have had including Pirelli Scorpions, Goodyear ICE and Michelin Pilot Alpin 5. The tire loves deep snow around the house as well as light snow on the freeway in and out of town. Ice, it does as well, or better, than the others (Scorpion was an excellent ice tire) tires I have had...
Best winter tire I have owned. We spend much of the winter in Tahoe at 6,800 ft elevation and we get a lot of snow most winters. The Blizzak is the best winter tire I have had including Pirelli Scorpions, Goodyear ICE and Michelin Pilot Alpin 5. The tire loves deep snow around the house as well as light snow on the freeway in and out of town. Ice, it does as well, or better, than the others (Scorpion was an excellent ice tire) tires I have had.
Dry weather, traction is good but I take it easier on them as I know they are not going to wear as well and I change them out every year in the fall and spring. Overall, highly recommend this tire for anyone in snow country. I only wish they made this tire for my Cayenne Turbo.

Excellent dry road performance too. The only difference from a summer tire is less precise handling and steering precision compared to a summer tire, still orders of magnitude better in those categories compared to other snow tires...

...But on dry, cold conditions, it was as good as the summer tires that came with the car. Slightly noisier, but great performance accelerating, cornering, and braking.
I ended up trading the car a few weeks after replacing the tires so I have limited experience with them, and none in snow/ice. But in dry, cold conditions, it was as good as the summer tires that came with the car. Slightly noisier, but great performance accelerating, cornering, and braking.

Surprising dry performance for a snow tire. Less grip in corners and easier to kick out the back end. An aggressive 1-2 shift can break the rear end loose at relatively high speed...

Best operated with traction control on all the time, but overall a great option for those who need a snow tire but don’t want to sacrifice their driving experience.

...So far, after just 500 miles, I'm not finding anything about these tires on the Lexus to disappoint... the tires are smooth, stable and perform well with ice and snow.
I have a lot of experience with Blizzaks on several vehicles, so when I got this Lexus NX 350h AWD recently I had no doubt I would have Blizzaks installed for winter driving. So far, after just 500 miles, I'm not finding anything about these tires on the Lexus to disappoint. Will update later with more miles driven, but so far, the tires are smooth, stable and perform well with ice and snow.

...The standard 245/45R19 all season have a bit more rubber and thus a smoother ride but less performance.
Still need to drive them for longer and more to know for sure. They are not technically rated for my vehicle but they hand better on it due to less rubber. The standard 245/45R19 all season have a bit more rubber and thus a smoother ride but less performance.

...They were more than acceptable in the snow for a low profile 255 width tire, but the treadwear is horrible. I blew through close to half the tread with less than 5K miles of city/hwy driving.
I had been happily running Dunlop Wintersport 3Ds for years on a M3 and a few RS4s, and always got at least 3 winter seasons of use. They were no longer available so I tried these. They were more than acceptable in the snow for a low profile 255 width tire, but the treadwear is horrible. I blew through close to half the tread with less than 5K miles of city/hwy driving. I mounted them this season on a 2021 S4 and they are probably the loudest tires I've ever had. I will be trashing them after this season..

These tires wore down way too quickly, compared to 4 other sets (Michelin X Ice and Bridgestone Blizzak) I have had over the past 15 years. The front tire shoulders wore down to bald after just over 5,000 miles... This is only a sample size of 1 set, but the tire wear is atrocious...
These tires wore down way too quickly, compared to 4 other sets (Michelin X Ice and Bridgestone Blizzak) I have had over the past 15 years. The front tire shoulders wore down to bald after just over 5,000 miles. Granted, this is my first EV, so it''s about 200 lbs heavier than the heaviest car I have owned. This is also the first set of "performance" winter tires I have had. The other winter tires all fared well after at least 5 winters.
However, I have not changed my driving style much over the past 15 years of driving in New England. If anything, I am slowing down a lot as I get older. I would assume that "performance" winter tires would not wear any faster than regular winter tires. If anything, they should wear slower because they are a less soft compound. This is only a sample size of 1 set, but the tire wear is atrocious. It seems like the other reviewer with the A6 Allroad found similarly quick wear.
