    End of discussion which tyres to choose for cars with multi-wishbone suspension, where the rumbles by slight usage can occur. It’s the best tyre in the world. It’s the opposite of summer Michelline tyre. The Michellines are built to win the tests. They are quiet, the resistance of trundling is small, the car consumes less fuel, but the Michellin is a tyre for grandpas – after driving 9400 miles it’s not possible to drive on wet surface with Michellin Primacy! On the other hand, BRIDGESTONE is awesome! Even after driving almost 19 000 miles the tyre is good during the rainfall, even though the usage is visible. The car consumes 0,5l more fuel, accelerates worse, max speed is also worse, but safety, but holding in the turns and during the rainfalls – great! Besides, it fits to every car. You can mount these tyres to Porsche, best BMW’s and Subaru in stock, so the 050A has got quite a recommendation! It’s funny for me, how the opinions on this portal differentiate. To everyone – it depends on how you drive! You can wear out the tyres in two days driving aggressively on the tour in a car with a power over 500 HP and also you can drive for 3 seasons 15 000 miles each.

    I think that the tyre is great. I’ll start with a disadvantage, which is a remarkable weakening of comfort. Driving on unevenness is sometimes very uncomfortable despite switching the suspension on comfort mode! There are also advantages of that fact. The car holds well by fast wheel moves, during hard breaking with ABS on I managed to miss a suddenly changing lane car! On wet, they lose the grip very late, on dry it’s obvious, because they are Bridgestone. Earlier, I had Bridgestones included to my Almera (but probably worse type and all-season’s) which was a tragedy. I sold them after 2 months, because I didn’t even want them to keep ‘just in case’ because they were dangerous. This model restored my trust for that brand. But it’s too rigid for me, so I’m changing for Continental Premium Contact 2 or Pirelli Cinturato p7 and I want a higher profile. If someone likes aggressive driving and hard safe suspension, then I recommend, but if someone has originally hard suspension, then for our roads I’d think about it. If we had German roads, I would probably stayed with those tyres.

    In Vectra, I had originally 215/55R16H tyre size - Bridgestone Turanza ER-30. With the new speed index W I bought Potenza RE050A. Behavior: accuracy, accuracy, accuracy - these are the main features of this tyre. In comparison with the previous one, the vehicle understeer disappeared somewhere. The reaction to turn the wheel is much more direct. Steering wheel stays stiff when driving straight ahead. The grip on the wet surface comparing to the previous one has improved, but this difference is not very large because of the narrower size which I applied. In terms of comfort, subjectively speaking, it is even better, though I was expecting worse. Car stopped swinging. With this tyre, unevenness is consumed at a time. There are no, as before, additional glides. The impact is perhaps harder, but no gliding compensates for this. The noise increased a little, but this is not a loud tyre. It’s just not particularly quiet.

    I decided to add my two cents, because the opinions of some Internet users should not be taken into account. 1. It is difficult to assess the values of a tyre in moderate driving – the chinese rubber is enough for that. Bridgestone RE050A work very well, but they are better. 2. Grip on wet roads also depends on the width of a wheel - the larger, the more carefully you should ride - wider sizes (over 225) require skill and caution. 3. Sport tyres are not hard, as some ‘smart guy’ wrote. Achieving a better grip is a price for faster usage. These bore one season driving fast, powerful car, so they are good. It’s a good compromise between hardness and abrasion. Overall, they are very good tyres, although currently I’m looking for something better. But we have different requirements and for calm drivers I do not recommend more expensive tyres - you will feel no difference.

    Made in Poland. The tyres shaved after driving 3100 miles. They have so much tread as new ones and they are already rubbish. Noisy at highway speed and interfere during phone calls, the steering wheel shakes in hands, not to mention the annoyance. I made a complaint with Bridgestone, of course, it was not successful, citing the abnormal tread wear for one of the following reasons: tyre pressure, suspension design, geometry settings, driving style, vehicle load, etc. This tyre model is factory-fitted in my car (BMW 320d), and is intended for such usage. Car was regularly serviced at BMW, where they confirm that the manufacturer always denies a responsibility. Because of this adventure, I will not pick the Bridgestone again, and for certain I will be heading in the direction of Pirelli and Continental.

Product description

Bridgestone Potenza RE050A 305/35 R20 104 Y RUN ON FLAT ZR

Bridgestone RE050A is summer-season tyre which has been optimized for regular passenger cars. The responsiveness and handling on dry roads is superb, and so is the grip and traction on wet roads too. In wet conditions, circumferential grooves quickly remove excess water, so the tyre has better tread-to-road contact and this reduces aquaplaning risks. A strong modern-day mix is used, and this repels mechanical damage, whilst also reducing rolling resistance, and carbon emissions and boosting fuel-efficiency.

Benefits of the Bridgestone RE050A:

  • Fuel-efficiency.

  • Reduces aquaplaning.

  • Excellent traction.

This tyre is produced by Bridgestone, which are one of the biggest tyre manufacturers in the world.

Bridgestone Potenza RE050A summer tyre is classified as premium tyre, which means that it provides modern technology and maximum performance.
Now, you are looking at the tyre with the size of 305/35 R20.
The tyre is currently available in sizes from 15 to 20 inches.
This tyre has a speed index of Y - the maximum speed at which you can drive on this tyre is 186 mph. The load index of this tyre is 104 - the maximum load that can be carried by the tyre is 900 kg.
The labelling of the tyre includes the following classes: E (rolling resistance), C (wet grip), 73 db (noise level).
The presented tyre has the following features:
  • RUN FLAT function (enables you to drive after air pressure loss)


The Bridgestone Potenza RE050A tyre in size 305/35 R20 104 Y, according to the manufacturer's information, has the following drivability qualities:

  • E
  • C
  • 73 dB
E C 73 dB

Fuel efficiency (rolling distance)

Fuel efficiency is rated from A to G on a colour-coded scale. The highest fuel efficiency rating is A (green; the lowest rolling resistance), while the lowest fuel efficiency rating is G (red; the highest rolling resistance). Rolling resistance influences fuel consumption and vehicle emissions; the lower the resistance, the lower the fuel consumption and exhaust fume emissions.

Wet grip

Wet grip is the tyre's ability to adhere to the road surface in wet conditions. The EU rating focuses only on the wet braking performance of the tyre. Wet grip is rated from A to G, where A represents the best braking performance and G represents the worst. It is one of the most crucial safety parameters.


Tyres contribute to the amount of noise a vehicle generates. Choosing a tyre with a good noise rating will lower the impact of your driving on the surrounding environment.
