Yokohama BluEarth-4S AW21 vs BluEarth-AllSeason 2

Not every driver wants the hassle of swapping tyres twice a year, and Yokohama has built an entire strategy around that preference. The BluEarth-4S AW21 and its newer sibling, the BluEarth-AllSeason 2, both promise year-round security on UK roads. And, while both do an admirable job, the latest iteration is designed to address the areas where the outgoing model falls short.

First out of the gate was the BluEarth-4S AW21, Yokohama's debut all-season fitment for passenger cars. Rather than starting with a summer tyre and bolting on winter capability, Yokohama leaned on its cold-weather engineering heritage, pairing a wide, flattened tread shape with angled water-clearing grooves and a compound that stays supple as temperatures drop. As a result, the BluEarth-4S AW21 boasts full Three-Peak Mountain Snowflake certification.

Building upon that reputation, the BluEarth-AllSeason 2 uses AI-assisted modelling to reshape the tread and boost the tyre's contact with the road surface, while a reformulated silica compound targets stronger wet-weather grip. A lighter belt construction also trims rolling resistance, giving the newer tyre an efficiency edge alongside the snow performance it inherits from its COLD TECH-based winter engineering. It's aimed squarely at the passenger car, SUV and EV market Yokohama expects to keep growing across Europe.

Here's how the two stack up against each other, and what Blackcircles.com customers make of them.
 

Yokohama BluEarth-4S AW21 Overview

The Yokohama BluEarth-4S AW21 is billed as an all-season passenger car tyre, built to carry drivers through changeable UK weather without the need to switch tyres between summer and winter.
The tyre's core technology is a silica end-locked compound, engineered to stay flexible as temperatures fall so the rubber can keep working the road surface even in cold or lightly snowy conditions. Yokohama pairs this with a flat, wide tread contour for stability, alongside divergent V-grooves and crossing narrow grooves designed to clear water quickly from the contact patch and protect against aquaplaning.

That winter-focused engineering has earned the BluEarth-4S AW21 the Snowflake mark, Yokohama's recognition for genuine cold-climate performance, and independent testing backs up its reputation on snow and in the wet: it has recorded shorter snow-braking distances than premium, mid-range and budget rivals alike in comparative tests, and owners consistently rate its wet and dry grip highly.
The wider tread and generous shoulder blocks also give the tyre a confident, planted feel on dry roads, rounding out a package built for genuine year-round reliability rather than excelling in just one season.

Available across a broad range of sizes from 14 to 22 inches, the BluEarth-4S AW21 remains a strong choice for drivers who want one dependable set of tyres capable of handling everything from summer heat to winter frost.

Yokohama BluEarth-AllSeason 2 Overview 

The Yokohama BluEarth-AllSeason 2 is billed as the next generation of Yokohama's all-season passenger car tyre, built for drivers of everyday cars, SUVs and electric vehicles who want true year-round capability without compromising on performance.

At the heart of the tyre is a redesigned tread pattern, developed using Yokohama's AI-assisted HAICoLab modelling to increase the tyre's contact area with the road by around 5%. That extra contact patch translates into real gains: according to Yokohama's own development data, the BluEarth-AllSeason 2 delivers a 32% improvement in dry handling and an 11% improvement in dry braking over its predecessor, alongside an 18% improvement in wet handling and 12% shorter wet braking distances. A reformulated, silica-rich compound helps drive that wet-weather leap, while the refined V-shaped tread channels water away efficiently enough to lift aquaplaning resistance by 17%.

The tyre hasn't lost sight of winter capability either. Yokohama's COLD TECH-based winter technology carries forward the snow confidence the range built its reputation on, with development data showing a further 7% improvement in snow handling. Longevity gets a boost too, with tread life up 35% on the outgoing model, while a lighter steel belt structure helps cut rolling resistance by 8%, making the tyre noticeably more efficient to run. Taken together, it's a substantial step forward across the board and shows Yokohama sharpening nearly every aspect of performance for this second generation.

Available across 74 sizes spanning 15 to 21 inches, you shouldn’t struggle to find a fitment that matches your vehicle, either.

Tyre Label Ratings

Tyre label ratings are regulated, and they are the only performance figures on either tyre that have been tested to a common standard.

They cover three things:

• Fuel Efficiency — graded A to E
• Wet Grip — graded A to E
• External Noise — a decibel figure and a class

Please note, ratings vary between sizes and fitment types for each model.

Yokohama BluEarth-4S AW21 Awards & Recognition

Since launching, the Yokohama BluEarth-4S AW21 has picked up recognition from independent certification bodies, particularly for its cold-weather credentials.

Key commendations and accolades include:

• TÜV SÜD Certification: Certified by the German technical testing authority after a rigorous benchmarking programme covering wet, dry and snow performance, including aquaplaning, wet and dry braking, snow traction, rolling resistance and noise (2019)

Yokohama BluEarth-AllSeason 2 Tyre Awards & Recognition

As a newly launched tyre, the Yokohama BluEarth-AllSeason 2 hasn't yet had the chance to feature in independent testing or collect industry accolades.

Unveiled to the media in Iceland in June 2026 ahead of a European sales launch in September 2026, it’s likely the BluEarth-AllSeason 2 will continue in the 4S AW21’s decorated footsteps.

Conclusion: Which Tyre is Right for You?

Rather than a straightforward face-off, comparing the BluEarth-4S AW21 and the BluEarth-AllSeason 2 is really a look at how far Yokohama's all-season engineering has come in a few short years, and what that means for drivers deciding between them.

The BluEarth-4S AW21 has spent several years earning its stripes as Yokohama's first foray into all-season tyres, and it's done so convincingly. Its silica end-locked compound and directional V-groove tread were designed to hold their own through UK winters without sacrificing warm-weather composure, and that engineering has since been validated by TÜV SÜD certification across a comprehensive set of wet, dry and snow benchmarks. For drivers who want a proven, road-tested option available right now, in sizes from 15 to 21 inches, it remains a dependable choice.

The BluEarth-AllSeason 2 takes everything the AW21 established up a gear. Yokohama's AI-assisted tread modelling and reworked compound technology are behind some striking development figures: dry handling up 32%, wet braking distances cut by 12%, aquaplaning resistance improved by 17%, and tread life extended by 35% versus its predecessor, alongside an 8% cut in rolling resistance for better efficiency. On paper, it's a substantial leap forward across nearly every performance metric that matters.

There's just one catch: the BluEarth-AllSeason 2 has only just been unveiled, with UK availability not landing until September 2026. That means it hasn't yet had the chance to rack up independent test results or real-world reviews the way the AW21 has. If you need capable all-season tyres today, the tried-and-tested AW21 is a great option; if you can wait, the AllSeason 2 looks set to raise the bar considerably once it reaches the market.
