The Best All Season Tyres for 2024

6th of 7 tyres

Very high levels of grip in snow, best ice braking, lower purchase price.
Low levels of grip in the wet, long dry braking, very high rolling resistance.
The Yokohama BluEarth 4S AW21 is another tyre that is better in the snow and ice than the dry and wet. It's not a bad product, and it was very good in the snow, but perhaps a bit too good for an all season tyre as it was firmly outclassed when not in winter conditions.

2024 ADAC All Season Tyre Test

14th of 16 tyres

The Yokohama BluEarth-4S tyre receives an overall adequate rating for driving safety. It shows significant weaknesses on dry roads at high temperatures and misses good ratings on both wet and winter surfaces.

On dry surfaces, the tyre offers barely adequate steering feedback and lacks precision. The driver must make frequent corrections due to delayed steering response and inconsistent cornering. The test vehicle tends to oversteer early in dynamic maneuvers, resulting in an adequate rating for limit behavior. Braking distance is rated as satisfactory.

On wet roads, the BluEarth-4S performs satisfactorily. It narrowly misses a good rating in braking tests, while its aquaplaning resistance and handling are clearly rated as satisfactory. The tyre struggles to effectively combine longitudinal and lateral forces and tends to under- or oversteer relatively early.

In winter conditions, the Yokohama achieves a satisfactory result. It scores well in snow braking but only satisfactory in traction and snow handling. The test vehicle offers satisfactory steering precision, but with a narrow and low performance limit. Ice braking performance is also rated as satisfactory.

Environmentally, the Japanese-made Yokohama BluEarth-4S receives a satisfactory rating. It achieves only satisfactory scores in projected mileage, wear, and efficiency. The tyre is criticized for production residues on new tyres, which unnecessarily impact the environment during initial use.

Questions and Answers for the Yokohama BluEarth 4S AW21

2018-12-11 - New XC60 4x4 (235/55/R19 V) comes with Latitude road tyres that are no use to me. I live on Dartmoor hence mud and stones plus some ice and snow. I need a sturdy all season tyre capable of a bit of off road but also capable of dealing with poor road conditions with gravel potholes and stones. Strong sidewalls. Currently using Yokohama Geolandars which last for ever but probably aren't the best in snow or in the wet. Looking at Scorpion Verde all season FSL with rim protector band. But the Verde is runflat M&S which seems like a good idea but how good on stones off road? Any suggestions - most other makes only have an H speed rating - I should have V though I'm not likely to exceed 130!

I'm afraid I'm currently out of my depth when it comes to SUV. This test includes both all season and AT tyres which are legal winter tyres and will give you an idea regarding the balance of performance.

2023-12-27 - Despite its mid-low ratings in all the tests, do you know something more about the Yokohama BluEarth 4S AW21 thanks

I'm afraid not, all the data I know is on the site.

Top 3 Yokohama BluEarth 4S AW21 Reviews

Great looking tyre with plenty of all round uniform tread.

Given 70% while driving a Suzuki vitara s 1,4 boosterjet (215/55 R17) on mostly town for 10 easy going miles

The first 2 years with these tyres was brilliant! Smooth drive quiet with very little road noise noticed. Summer months the tyres were fine not very sporty, noticed as the temperatures got up to 30°c they felt very soft going around corners.
Autumn into winter is were these tyres are great! The wet grip is excellent and feels like a normal summer tyre. When the snow arrived I was really impressed how much grip they gave going up hills even braking on snow was very good. Into the 3rd year of ownership and cracks started to appear on the tread blocks where it contacts the road, also noticed that road noise has increased with the ride feeling harsher than before. Seems like most all season tyres suffer from this hardening of the tyre surface into the 3rd year of use. I doubt I would buy these again due to this.

Volkswagen (225/45 R17) on mostly country roads for 1,000 spirited miles

I can't comment on snow and ice grip as yet but dry and wet grip perfectly acceptable (Golf MK 6 1.2 TSI) through some spirited driving. Only downside is steering feel when manoeuvring - tyres give very odd sensation but nothing so bad that would stop me buying again

Given 95% while driving a BMW 435d (225/45 R17) on a combination of roads for 2,000 easy going miles

They have been excellent over the winter months, they feel very solid on seriously wet roads and motorways and when it has been icy there hasn’t been any slip or loss of traction when accelerating or braking. No use in snowy conditions or warm hot weather as yet. Very glad I swapped my Primacy 3’s, nice in the dry but to me they didn’t feel solid particularly on wet motorways, these are a vast improvement in the wet.

OE tyres G95A by Yokohama, M+S designed with not that good performance on wet. Tyres are somewhat designed for "all terrain" use, Geolandar series, so it was not a surprise. Then I switched to G055 M+S tyres over again, good tread wear, good in the wet and in the dry, sufficient in the snow as the G95A was -the AWD proved axcellent and overtaking winter tyres equipped cars-. Last I put on weather control A005 from Bridgestone, very good in dry and et, but too winter oriented and soft compound, tread wear not an asset at all -blistering noted on the edges after 30,000 km, trew them away. I drove 80,000 miles with the liste tyres, then I put on the 4S AW21, giving credit to Yokohama first real all season tyre. They are developed from a summer tyre as far as I know, I hope this is true as the tread depth is not excessive. So far so good, wet and dry performance is very good, cornering in the wet is excellent wiht my car. Only lihgt snow tested, but I do not pretend that much as I rely on the AWD and even a fair performance becomes a good performance thanks to the symmetrical AWD with the viscous centre diff and limited slip, so the snow and ice ratings are not a reason of choice for me. First impression was they are a bit better than the Bridgestone A005, but performance may dramatically change according to tyre size and vehicle, on my car this tyre by far outperforms the bridgestone A005, althouhg my expectation was not to that direction.

Given 51% while driving a Skoda (205/60 R19 H) on a combination of roads for 14 average miles

I fitted 2 YOKOHAMA "BLUE EARTH" tyres to the front of my car May 2017.After only 14,632 miles one had a crack running the full circumference of the outer tread next to the outer wall. I found it very difficult to contact YOKOHAMA and l still had no reply after 3 weeks. AVON ZV5 same size fitted to the same position on the same vehicle reached 21,145 .Fitted to the rear 28,000, performance wet and dry roads was very similar to that of the YOKOHAMA.
