    I bought the tyres in August 2013, I drove about 30 thousand km on them. At that time they cost less than 300 PLN each, which is one of the cheapest, so I did not expect anything from them, but I am very surprised with their quality. I have a positive opinion about the grip on both dry and wet surfaces, they don't squeak, they don't slip when starting off or when braking, unfortunately they are not very durable, but that's probably why they grip so well. I think they will last for another 20 thousand km at the most, and then I will have to change them, although I would like to point out that I mainly use the car on highways at high speed. I should also add that they are relatively quiet, they don't throb at all, even after a considerable mileage. Being new, they did not require excessive weighting, also after a whole season a minor adjustment was enough. For those who drive fast, I would add that 250km/h does not make much of an impression on them.

    Purchase made rationally in view of driving style. The tyre is quiet even at high speeds. In wet conditions it can break traction on a curve when accelerating hard, but even 3x more expensive Pirelli tires react like this. This is my second set of oriental tyres, the previous ones were from Taiwan and after 30k they still had about 7mm on them. I am not keen on labels or brands, so I bought Phi. The quality/look/price ratio is sensational. If I had the opportunity I would love to test them on a track to feel the limits of grip. In civilian use nothing bad happened on the road. I really recommend it, because I think that 3-5 years are more than enough for a small man and it lasts about 50-60 thousand km. One disadvantage in my opinion: 7 mm tread in the middle, about 4-5 mm on the sides. I don't know about other brands in 225/45/18 size, because maybe this size is like that, but if other brands have 8 mm tread.

    This is the third set of summer tyres in my car, first there were OEM Dunlop tyres, then Bridgestones. I've covered 4500 km on these tyres and I don't see any major differences compared to the branded ones. Right after fitting them, for the first 50 km they made a slight noise in corners, then it went away. There were no problems with balancing, they fitted very quickly on the rims and nothing disturbing happened. The fastest I could do was 180 km/h in the dry and 150 km/h in the wet. And I can tell you that they are a sensation. They drain water very well in the rain. They are minimally louder than the previous ones (maybe because I listen to them more now), but not really loud. If they are ever available again, I will buy them for sure. You won't buy anything better for the price, and in fact I think paying a horrendous amount for branded tyres is cheating the manufacturers. Regards

    hello this site scared me at first.since i buy everything at OPONEO.they are pro/very fast delivery never had a single problem even for the assembly centres BRIEF PERFECT I started by putting some on my 7 e38 series two in the front at the beginning and then two more in the back as I was very I highly recommend.I put four on my 2010 a8 / 4.2 quattro audi a8 / 4.2 quattro in 255/35/19 and they are perfect not to mention the price which has nothing to do with the michelins and others.... I will soon be recommending 4 of them for my clio dci My only doubt is that the price of the accelerators will increase. OPONEO AND ACCELERA DESERVE TO BE KNOWN. I have no shares in them......

    I bought them because of the price and because I like to experiment. For the price, because I like to drift and I don't want to have to worry about the cost of the tyre every time. I like experimenting because I think that even an unknown brand has the right to be tested. As far as this tyre is concerned, as soon as it was fitted in the dry I was impressed, even though it wasn't a continental or a pirelli it seemed honest. Then the rain came and all the tyre's limitations came to the surface. It has no lateral grip and even if I don't accelerate, even with the controls on, the car drifts even at very low speeds. If it rains every now and then in your area, do NOT buy it.

Product description

Accelera PHI 245/40 R21 100 Y XL

The Accelera PHI is an economical solution designed for use in sports cars. In order to ensure a faster driving experience, the designers have used an innovative rubber compound, which offers optimal performance at high temperatures, allowing for the tyre to be used for longer. This means that the tyre does not wear quickly and maintains its optimal performance specifications for longer.

The special, asymmetric tread design with additional reinforcement ensures resistance to mechanical damage and deformation at high speeds. The tread design also features simple grooves responsible for good steerability and protection against damage. The reinforced shoulders maintain driving stability in all weather conditions. The tread grooves allow for effective water dispersal, as well as reducing tyre temperatures at high speeds, minimising the risk of aquaplaning and maintaining optimal safety levels.
