    Questions and Answers for the Yokohama BluEarth 4S AW21

    2018-12-11 - New 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!

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

    OE tires G95A by Yokohama, M+S designed with not that good performance on wet. Tires are somewhat designed for "all terrain" use, Geolandar series, so it was not a surprise. Then I switched to G055 M+S tires 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 tires 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 tires, then I put on the 4S AW21, giving credit to Yokohama first real all season tire. They are developed from a summer tire 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 tire size and vehicle, on my car this tire by far outperforms the bridgestone A005, althouhg my expectation was not to that direction.

    I fitted 2 YOKOHAMA "BLUE EARTH" tires 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.

    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.

    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 - tires give very odd sensation but nothing so bad that would stop me buying again
