Yokohama BluEarth-A AE50

Due to the recent covid lockdown, I have not been able to drive much so it is a bit too early to provide a proper assessment. There have been no problems so far. The road noise is a bit louder than I was expecting but then again I am only comparing them to my last set of tyres. Those were Yokohama Geolandars that I replaced after 66,000 miles and eight years because they started to perish, even though they were still road legal. I hope the BluEarth range performs as well as the Geolandars.

3/5

Yokohama BluEarth-A AE50

I would say the tyre has good grip, however when driving over 60 it is much more noisier than the last one.

4/5

Yokohama BluEarth-A AE50

I drive every day and nearly all of my driving is done on country roads. I was very pleased with how these tyres performed even with the snow. I do tend to put my foot down a little heavier then I should, but with my old tyres I used to have a lot of wheel spin, whereas now that has basically gone. For the last ten years I've had Yokohama tyres on my last six cars, and would always be left impressed.

5/5

Yokohama BluEarth-A AE50

These tyres are great for road use, with dependable grip regardless of the weather, and they are quieter than the usual multi-purpose tyres that come with the Outback. They do, however, need higher than normal air pressures, as they can look a bit deflated.

4/5

Yokohama BluEarth-A AE50

The tyres meet my expectations. This is my second car and I don't do many miles in it. I drive carefully and don't push it to hard on the public roads, so I can't comment on how these tyres affect drifting round roundabouts like some reviewers. Overall, I would buy them again.

What Does 185/45 R17 Mean?

185/45 R17 tyres are found on Smart cars, especially the Brabus fortwo and forfour models and on Renault's Twingo GT. The digits are easy to understand. 185 means the width in mm, 45 indicates the aspect ratio, meaning the sidewall is 45% of 185mm, which gives an 83mm sidewall for the front while these rear-engine cars have a wider rear tyre, and R17 refers to a 17-inch radial tyre. This brings the overall diameter to 598mm. We have 185/45 R17 at Tyres.co.uk.
