The Turanza EL400-02 and Turanza EL400 w/UNI-T are Bridgestone's Standard Touring All-Season tires developed to meet the Original Equipment and replacement tire needs of drivers for their sporty coupes, sedans and vans. Turanza EL400 tires are designed to provide a luxury appearance, long wear and responsive handling along with dry, wet and year-round traction, even in light snow.
Bridgestone's Ultimate Network of Intelligent Tire Technology (UNI-T) features three core elements: CO'CS, a Computer Optimized Component System which allows design and manufacturing processes to work more cooperatively, leading to a more effective tire that doesn't significantly sacrifice one area of performance for improvements in another; O-Bead, a rounder bead structure that minimizes overlapped joints in the bead area for improved ride; and L.L. Carbon (Long Link Carbon) which helps the rubber compound resist microscopic tread tearing related to wear.
On the outside, Turanza EL400 tires features their tread rubber compound molded into a symmetric tread design with straight circumferential grooves to balance dry and wet road traction with noise comfort and hydroplaning resistance. On the inside, the Turanza EL400 features twin steel belts for strength and stability with a polyester cord body to enhance ride comfort.
*Specific sizes featuring UNI-T technology are identified as such on the Sizes tab, as well as on the tire's Specs tab.
Los neumáticos Turanza EL400 y Turanza EL400-02 de Bridgestone pertenecen al grupo Turismo Estándar Para Toda Estación y han sido desarrollados para cumplir con las necesidades de conductores de autos deportivos cupé, sedán y vans en cuanto a Equipo Original y neumáticos de reemplazo. Los neumáticos Turanza EL400, han sido diseñados para proveer una apariencia lujosa, características sobresalientes de desgaste y mayor maniobrabilidad; sin hacer concesiones en tracción sobre superficies secas y mojadas, durante todas las estaciones, inclusive en superficies cubiertas con poca nieve durante el invierno.
La tecnología UNI-T de Bridgestone consiste de tres tecnologías fundamentales: CO'CS (Computer Optimized Component System) ) es un proceso computarizado que optimiza el diseño de bandas de rodamiento, la forma de la carcasa, los materiales y la construcción para lograr el máximo rendimiento del neumático; O-Bead elimina la unión traslapada en el cable del talón o alambre de aro, utilizando un cable único y continuo. Esto crea un neumático más redondo, lo cual mejora el andar; Long Link Carbon (Carbón de cadena larga) es un material de refuerzo mejorado que aumenta la resistencia al desgaste y disminuye la pérdida de energía del caucho.
La construcción externa del Turanza EL400, presenta una mezcla de caucho moldeada en una banda de rodadura con diseño simétrico. Canales circunferenciales rectos encuentran el balance entre tracción sobre superficies secas y mojadas, niveles de ruido más bajos y resistencia al deslizamiento en agua (hydroplaning).
Internamente, correas gemelas de acero proveen fortaleza y estabilidad, mientras que, una capa de cordón de poliéster aumenta el confort del andar.
*Tamaños específicos que cuentan con la tecnología UNI-T son identificados, como tales, en las páginas de Tamaños y Especificaciones.

Why Gamble With Winter Tire Selection When Four of a Kind Always Beats Two Pair?(01:56)
Some drivers still doubt the industry's requirement for equipping front-wheel drive vehicles with matching winter tires all the way around. To address those doubts and demonstrate what can happen when mixed tires reach their limits on hard-packed snow and ice, we did some tests at our local skating rink.
Feedback consistently shows the Toyo Open Country A/T III excels in dry traction (9-10 scores dominate) and wet performance, with strong hydroplaning resistance. Winter capabilities shine in snow and deep snow, though ice traction earns slightly lower but still positive marks (7-10 range). Drivers praise its rugged stability and responsive steering for off-road use, while ride comfort earns consistent 8-10 ratings. Noise levels are manageable for an all-terrain tire, though some note occasional hum. Treadwear receives widespread praise (8-10 scores), with many highlighting durability across mixed surfaces. This tire delivers confident performance in its intended off-road/all-terrain role, balancing aggressive capability with everyday drivability.

...Water traction is fantastic, I have no idea when people write it's not good. I have tons of sipping and drive careful and never had it slip...
This tire is simply incredible! I would buy again. It’s very quiet, almost difficult to even notice the sound unless I’m looking for it . I am driving a Standard load version, took about 1-2.5 oz to balance each tire! Butter smooth in the roads.It truly feels like a highway tire but with the advantages of the all terrain. I couldn’t be happier. Toyo made a great tire with this one. Sidewall looks cool and mild aggressive patterns. I super dig the style and tread. Water traction is fantastic, I have no idea when people write it’s not good. I have tons of sipping and drive careful and never had it slip. A+++ tire! It’s the best fit for my 2019 tundra I’ve ever found.

I really like fact that the road noise is down to a minimum compared to the BFG KO2. It has much better wet traction also. I did notice that I lost some gas mileage, which is weird since I went from a E load rated tire to a C load rated tire. All in all I am very happy with my purchase.

...I noticed in snow when turning into may begin to slide but straighten back up and it grabs immediately...
Off-road ability is great. I've had no problems with loose gravel, sand, and mud. I noticed in snow when turning into may begin to slide but straighten back up and it grabs immediately. For me I do anywhere between 500-2000 miles a month. From the starting 12.8 32nds depth having done about 7000+ miles im at about 10 32nds remaining. However, one of my tires are now starting to cause vibration. Looking back I think it was a bad tire because the amount of balance weight added to that tire was rather high compared to the other 3. Hoping I'm just a rare occurrence but will likely have to buy another pair to stop the vibration that one is causing.

I have been happy with the performance of these tires...
I bought a set of used Toyo tires, due to wanting the Jeep 392 wheels they were mounted on. They still had fair/good even tread. With winter coming on at the time, I wanted a new set of treads. Since I was impressed with the style, tread depth, weight of tire, and low noise, I decided to buy a new set of these Toyo Open Country AT III's. I've done mostly highway/city driving , one winter trip in the mountains, and some minor off road at farms/parks but nothing that any tire would have issues with. I have been happy with the performance of these tires, I would like to see how they handle more off road conditions and time will tell on that. I was in a heavy downpour recently on a trip and didn't notice any hydroplaning at speeds up to 50-60mph, there was quite a bit of water on the highway at that time, and for safety I did lower speeds in some of the tighter mountain curves, while everyone else was traveling slower. Great set of tires so far. I also like the 11.5 width keeping the tire within the fenders so I'm not flinging dirt and rocks on my doors and at others.

...On road I've got no complaints. I was even surprised that there was very little road noise...
Purchase these tires for my trail hawk and so far I'm extremely happy with my purchase. I've only had them for a few months so we will see how they rate once I get more time to play with them. Cosmetically, they're exactly what my Jeep needed. Functionality wise, so far so good. Had a chance to take them out in a muddy farm field and they worked like a charm. On road I've got no complaints. I was even surprised that there was very little road noise. Can't wait for the snow to start flying and see how they hold up to the weather in the NE.

I am pleasantly surprised that they are even quieter than my previous tires and the ride is so much smoother...
I replaced my 4 Michelin tires which had 40Kmiles even though the tread was still 5/32", within safe limits. But I wanted a better tire for the snowy weather here in Buffalo NY. These Toyo tires are much more aggressive in snow but I was worried that they would be noisy. I am pleasantly surprised that they are even quieter than my previous tires and the ride is so much smoother. Also I noticed easier cornering and steering in general. I love these new tires and looking forward to how they handle in the winter.

This tire... seems to wear well
This tire seems to be an attractive addition to the stock tires and does not degrade performance actually gives a smoothie ride and very little road noise Overstock substantially increase traction I say it's an overall good tire and seems to wear well

...That being said I have just a touch over 60,000 miles on these tires & they do still have decent tread & even wear...
My main issue with the tires is almost a year after having them installed, they started to dry rot. I went back to the shop I purchased them from & they reached out to Toyo & I was told that dry rot was to be expected and pretty much told me “it is what it is”. I’ve had several sets of Toyo’s mt’s and even a set of rt’s without any issues with dry rot. I just wasn’t expecting that with the at3’s. That being said I have just a touch over 60,000 miles on these tires & they do still have decent tread & even wear. I rotate them every oil change & they are starting to get a little noisy but I guess I can’t complain too much, I just really didn’t expect dry rot in a reputable brand of $1600 tires

Are Front-Wheel Drive and All-Season Tires Enough for Winter Driving?(02:33)
Drivers living in the northern U.S. have already discovered a set of dedicated winter/snow tires increases their vehicles' wintertime capabilities enough to reduce their driving times, tension and stress. However, if you're among the skeptics who still question if the added traction is worth the expense, watch this video.
Testing on Ice: Winter / Snow vs. All-Season vs. Summer Tires(03:38)
First we tested all-season and winter / snow tires on our snowy test track.
Now watch as we compare the difference between winter / snow tires, all-season tires and summer tires by evaluating acceleration, stopping and cornering capabilities — this time using an ice rink as our test track.
