Yokohama BluEarth 4S AW21
WatchThe Yokohama BluEarth 4S AW21 is an all-season touring tire that prioritises cold-weather reassurance, with drivers commonly praising its wet grip and light-snow confidence. In independent testing it can deliver strong snow/ice stopping power, but it struggles to match class leaders in key summer metrics. Overall, it feels like a winter-leaning all-season option rather than a balanced year-round benchmark.

All Tests
View Test ResultsThe Yokohama BluEarth-4S tire 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 tire 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 tire 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 tire is criticized for production residues on new tires, which unnecessarily impact the environment during initial use.

Questions and Answers for the Yokohama BluEarth 4S AW21
Ask a questionNew XC60 4x4 (235/55/R19 V) comes with Latitude road tires 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 tire 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!
Despite its mid-low ratings in all the tests, do you know something more about the Yokohama BluEarth 4S AW21 thanks

Top 3 Yokohama BluEarth 4S AW21 Reviews
The Yokohamas seem more winter oriented and they are overall decent, I have not noticed anything unusual, except for the road noise which is a bit of a killer. They legitimately howl like banshees :D I am not going to buy these again mainly because of that.
Autumn into winter is were these tires are great! The wet grip is excellent and feels like a normal summer tire. 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 tires suffer from this hardening of the tire surface into the 3rd year of use. I doubt I would buy these again due to this.
