AW21

Previously I drove on Firestone Multiseason 2, which are my point of reference. Unfortunately they have dry rotted prematurely so I have opted to go for a different brand (on a side note the car was stored in harsh conditions so I can understand that that was the main issue).
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.

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.

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.

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.
