1. Bridgestone Alenza A/S Ultra - Best All-Season Tire

Let’s get this list going with the Alenza A/S Ultra from Bridgestone. With the Alenza A/S Ultra, Bridgestone’s engineers had the goal of an all-season tire that can deliver traction year-round with the handling, low noise, ride comfort, and long wear of a Grand Touring tire. The Alenza A/S Ultra is designed around a polyester casing reinforced by two wide steel belts and a nylon cap layer package for high-speed stability and luxurious ride quality, along with a silica-rich tread formulation that delivers long wear, noise reduction, and unbeatable wet-weather grip. The Alenza A/S Ultra’s tread features include lateral grooves and wide circumferential grooves that divert water away from the tire’s contact patch to avoid hydroplaning, a dense network of 3D sipes, and Bridgestone’s Snow Vices groove design for consistent traction in wet or wintry conditions. The Alenza A/S Ultra’s solid center rib delivers great steering response and on-center stability at highway speed, and its tread pitch is computer-tuned to help negate certain resonances and frequencies and keep road noise to a minimum. Bridgestone backs the Alenza A/S Ultra with a generous 80,000 mile manufacturer’s treadwear warranty.

With an average SimpleScore of 9.6 out of 10, the Alenza A/S Ultra offers excellent handling (9.0), traction (9.1), and longevity (7.2).

2. Yokohama Geolandar X-CV - Great All-Season Tire

Next up, we’ve got the Yokohama Geolandar X-CV, an all-season tire that’s specifically engineered for the driving dynamics and performance of today’s SUVs and crossovers. The Geolandar X-CV boasts an all-season tread pattern with four circumferential grooves, a staggered pattern of 2D and 3D sipes, and a silica-infused rubber formulation for improved wet-weather grip. With those tread features, the Geolandar X-CV gets a SimpleScore of 8.6 for traction. The braking properties, cornering, and steering response of the Geolandar X-CV are all pretty impressive, too, with its stable internal construction and rigid, reinforced shoulder that’s reinforced to stand up to the forces and inertia of cornering. SimpleScore for handling: a very strong 9.1. Yokohama backs the Geolandar X-CV with a 50,000 mile warranty. That's some pretty great warranty coverage for a longevity score of 8.4, according to SimpleScore rankings. We should also mention that this is a tire with a cathedral-quiet ride, thanks to a five-pitch tread pattern that’s randomized and tuned to negate certain resonances and frequencies and mute road noise.

3. Pirelli Cinturato WeatherActive - Best All-Weather Tire

Next, we’ve got an all-weather tire from Pirelli, the Cinturato WeatherActive. For many drivers, the all-weather tire category might still be unfamiliar. In contrast, all-weather tires have a lot of similarities with their all-season counterparts; they’re also built with an emphasis on improved performance in winter conditions. That’s all without real tradeoffs regarding handling, braking, ride quality, tread life, road manners, noise levels, and cornering dynamics. For decades, Pirelli has been a favorite of drivers everywhere for its innovation, value, and quality, and the Scorpion WeatherActive is a tire that lives up to Pirelli's reputation. The WeatherActive is a newer iteration of the proven Scorpion family of tires; it’s certified with the tire industry’s Three Peak Mountain Snowflake rating for severe winter service. On the pavement, the Scorpion WeatherActive delivers braking and cornering that are light, nimble, and precise with a stiffer sidewall, 3-rib directional tread pattern, and a shoulder that’s reinforced to handle the g-forces of hard cornering with minimal deformation and tread squirm. In wet conditions, the Pirelli WeatherActive fights hydroplaning with a zigzag central groove and angled grooves that channel water and slush through and behind the tire’s contact patch. You’ll love the dead-quiet ride of the WeatherActive, too; its tread pitch is computer-tuned and randomized to keep road noise to a minimum on the highway by canceling certain resonances and frequencies. The tread compound of the Pirelli WeatherActive has durability for damage resistance, great wear properties, and long miles, but it stays pliable for winter grip In subfreezing weather. Pirelli covers the WeatherActive with a 60,000 mile limited manufacturer tread life warranty. After putting together all the numbers for the WeatherActive, we came to SimpleScores of 9.8 for traction, 9.2 for longevity, and 9.5 for handling – the kind of scores that show the Pirelli WeatherActive to be not just a great performer but a great value all around.

4. Nokian Hakkapeliitta 10 SUV - Best Winter Tire

“Hakkapeliitta” is a word that most Americans probably haven’t run across… in case you wondered, it's Finnish for that country’s 16th-century cavalry troops. Finland-based Nokian (yes, the same parent company as Nokia phones) has decades of experience in winter tires that can meet the challenges of safely getting a driver through a tough Scandinavian winter. Here at SimpleTire, we’ve been fans of Nokian tires and the Hakkapeliitta 10 SUV for some time. If an ice storm comes through and leaves your roads skating-rink slick, you’ll probably find that studded tires are the only thing that can safely get you from point A to point B and back again. The Hakkapeliitta 10 SUV is pre-drilled to make it easy for a tire shop to install studs (check your local and state laws for the legality of studded tires). Its stud pattern is strategically designed to deliver the best traction with minimal impact on the pavement while keeping noise to a minimum. Its tread pattern incorporates a system of angled, sweeping grooves and a dense network of sipes for consistent and stable control and traction. Its rubber formulation is engineered to stay flexible for grip in subfreezing weather, bringing in a SimpleScore of 9.9 for traction. With those credentials, it shouldn’t be surprising that this tire is Three Peak Mountain Snowflake rated for severe winter service. Longevity is also a real plus with the Hakkapeliitta 10 SUV, thanks to its tough internal construction, durable Aramid-reinforced sidewall, and a long-wearing rubber compound for a 9.1 SimpleScore in that category. The rigid sidewall, shoulder, and tread face all help with cornering and braking, enough for a SimpleScore of 8.9 for handling. We should note here that the Nokian Hakkapeliitta 10 SUV is also designed for low rolling resistance, saving fuel over the tire’s service life.

5. Falken Azenis FK460 A/S - Best UHP All-Season Tire

Just about every tire in the Falken product line has made a great impression on our team here at SimpleTire for some time now, and the Azenis FK460 A/S is no exception. The Falken Azenis FK460 A/S is a premium tire you can feel confident about for its versatile grip in all kinds of weather, with its advanced 4D Nano tread compound. In most cases, it’s just intuitive that tires will lose traction as tread depth wears down. Still, the innovative Emerging Grooves tech of the Azenis FK460 A/S is designed to widen the grooves and open them up for extended performance even as tire depth gets shallower. The Canyon Groove design and circumferential grooves with chamfered edges are designed for dependable control in wet or wintry conditions; they all work as a system to deliver the grip you need for a traction score of 8.6. Thanks in part to the wear properties and durability of that 4D Nano tread compound, Falken covers the Azenis FK460 A/S with a 50,000 mile manufacturer’s treadwear warranty, enough for a SimpleScore of 9.1 for longevity. Braking performance, steering response, cornering, and road manners are all nimble and dead-on with this tire, which results in a SimpleScore of 8.8 for handling. We can’t forget that the Azenis FK460 A/S is composed and quiet on the highway, with acoustically tuned grooves to keep road noise to a minimum by cutting wind noise and muting pattern noise. The overall SimpleScore for the Falken Azenis FK460 A/S is a very strong 8.7.
