I've a rear wheel drive V6 and these tires are average in the dry and a complete waste in the wet.
They came already fitted to the car, so thought I'd give them a go. Jut ordered some Pirelli as I'm so unimpressed.
They don't age well, they have gone a dull rubber look after only a couple of months (about 3000 miles), so they spoil the look of the car. (yes I clean and detail).
In the dry, they're ok. Not great, but ok.
In the wet they're a complete nightmare. Having a torque'y rear wheel drive car means you have to slow right down. I have to go slower than 1 litre Micra exiting a roundabout, they offer no grip at all on a damp road. The traction control light is constantly on, even when in safe mode.
these tires would suit a company car on a commuter route. They'll do the job at a great price, so for those drivers and aspects I would recommend.
For a car with any grunt or even any rear wheel drive car I would avoid like the plague in the UK. They're not for twisty roads, roundabouts or even a hint of moisture

The varied reviews on the this tire are insane. Some calling them dangerous to the best tire ever driven on to date. My review is based on driving at legal speeds. Average 80 to 120kph.
On my Irish dry roads, the car handles well and confortable giving good feed back steering through the corners and braking. In heavy rain, I slowed down and again the tires are fine. On greasy wet main roads, the tires were giddy accelerating away from lights, fighting for grip as I put my foot down. So if you don't want spin - don't race! Once I adjusted my driving style to the tires, they were acceptable.
In summary, my view is that once these tires are that driven legally, they are good for the money on a family car driving safely. Its like the Top Gear corner Follow Through - different cars and drivers can go at different speeds. (Bring back the old Guys!) But if I had the money and did my research and wanted to enjoy the full potential of my car and all its power, I would go for the drivers tire- Michelin Pilot Sport 4. If I want to maximise fuel economy and long life I'd drive on the Michelin Primacy 3. Both the same price, but different handling qualities. In my view, Mid range brands are just made to suit peoples budgets.

For the money these are great tires. I think the best budgets around. In the dry they are very good, with comparable grip levels to my previous kumho ku39's. They also have great rim protection, far better than the kumho's, I was shocked!

As others have said they aren't good in the wet, not at all. Now if you drive slowly in the rain like I do then these tires are more than safe, however if you do fancy giving it a bit you will find these instantly slip (atleast they do in my rear drive 330d). But that's not a problem for me, as I drive cautiously when the roads are wet.

Other little niggle are the sidewalls. They are soft and you can feel the tires flexing under hard acceleration, its not massively bad, but noticeable.

These are great tires considering these were half the price of the kumhos, Wear seems good too.

So i bought these tires for my 2014 mustang gt and i must say it has been
The biggest mistake i have ever made !!!
After 16000 miles the right front tire started showing threads!
So i tried contacting my dealership who informed me that
There was nothing they can help me with and that those tires have no warranty
So now im here ready to sew accelera and my ford dealership (gosch ford temecula ca) all together
If u want to be safe do not buy these tires a bycicle tire wuldve lasted longer!!

First off I'd like to mention I am trying these tires out as an experiment to see if I really need to spend a lot of money on Pilot Super Sports. The Bridgestone re050a 205/40/17 that came stock on my car were very grippy. I exceeded .95 G's in a few very nice roads here in California. I have had those replaced while they were still in good shape. They had 4000 miles on them of mixed driving with 8/32 of wear on fronts and 10/32 on the backs. I do not wish to ruin them on my daily drive. So that is where the Accelera Phi-R comes into play. The tread wear is 400 so they will take the beating for the time being. I took them up GMR (Glendora Mountain Road) which was beautiful for a drive 85* f and absolutely no one in my way. The Phi-R tires are a little slower to respond then the stock re050a. They are also much quieter in a straight line! More comfortable too giving it that heavy car plushness. But around corners they grip, communicate, and rip! Easily pushing .9+ G's in some hairpins. They get louder the harder you corner and I could not seem to break them loose. There was a faint hint or under steer in the first couple corners because they were brand new and the mold release was still covering them. After that they were fantastic and had no off characteristics. So in short they are UHP tires, not a MP tire. Nicer ride, but slower to respond. Better wear life, but unnoticeable reduction in grip. I will be taking this car with these tires for a 300+ mile trip up the California coast on PCH and will come back to make better correction of these notes.

These came on my insignia vxr and I have to say they are awful. At first I was disappointed with the car as the tendency to under steer and the front wheels to skip in the wet. Under hard acceleration if you hit a tiny puddle of man hole cover they snatch the wheel in a violent and dangerous way. I've just swapped them for pilot super sports as I've always gone for pilot sports in the past on my other cars and found them great but the size of these makes them double what I've paid before. It was certainly paying the price for because now I realise that it wasn't the car that disappointed me, it was the tires.

This is the second set of accelera tires fitted to my ford mondeo titanium x sport (1997 cc) and I do around 50k miles per year and I have to say that for commercial use on mostly motorway carriages I can't fault these especially when you consider the price. I notice most of the adverse reviews are from owners of high performance cars who feel the need to corner harshly on roundabouts and since I'm not a simple boy racer I will be happy to fit another set to cover the next 30,000 miles.

At first these tires were fine, really pleased having dropped the run flats ... and then it rained! Wow, I've never thought about a tires wet performance before, and I'm a confident, and often spirited driver. At first they were terrifying in the wet, very little wet progressiveness, huge understeer, wagging back end, often lost traction on roundabout's ... quite a few brown moments! I'm not sure if they've improved, or my driving style has grown into them, however I have learnt that its certain types of wet road surface they dont like. They do seem a lot better these days; however I wouldn't buy again, as the backs ran off fairly quick for mainly motorway miles.

I have had two full sets of these 225 45 18 tires, first set covered 35,000 miles, very good, second set much the same, handle very well but tended to break away on hard cornering, will buy and just have again.

Had these on a 62 plate Smax. Kept going out of balance, later worked out why. At motorway speeds for an hour the car would begin juddering and get progressively worse. After allowing tires to cool in a service station for 40 minutes, the judder would be gone, only to return again an hour later. Heat was making these very dangerous tires deform. I will never use them again. Have now swapped them for falken brand which are about 30% dearer, but much better in grip/handling and have no heat deformity.

Wet grip = Horrendous. The back end has come away and oversteered on roundabouts in the wet on a few occasions. This was driving at speeds I usually would have with the Hankook Venus V12 EVO K110 tires (HIGHLY RECOMMEND) I had fitted prior to the Epi Accelera PHI tires. Unexpected yet a good laugh nonetheless. Tokyo drifting around roundabouts! I also had an instance where I exited a roundabout (no drifting on that occasion! Boo!) onto a dual carriageway with a slight uphill gradient, I put my foot down in 2nd at low speed to get up to speed and also to leave some cock end in a pimped up BMW 320d E92 behind due to him being provocative via tailgating my the rear wheels lit up and the car snake tailed... regained traction easily enough and the roads were damp to be fair. It was either that or I'd have brake tested the little shit for being so irresponsible. I'd have won with the 4 piston Brembo monobloc's on all 4 corners. It wasn't like I was driving like a granny! Must have had the Porsche/BMW inferiority complex. To conclude; great in the dry, shit in the wet. So if your car is RWD be careful moist/damp and wet roads!

I can't believe how a tire can differ so extremely on different road conditions.

These tires are surprisingly well balanced on dry surfaces. They perform amazingly good even when pushed their limits. Everything is rosy until you start driving on wet/rainy roads. Even though I was recommending these tires to my friends because they are made by the same factory who were used to produce Continetal Sport Contact 2 and the design is the same, they have nothing related with the Conti's. These tires are the worst and most dangerous tires I have ever driven in my life. They have literally 0 grip and braking is an horror story. Several times I went in really dangerous situations because the tires couldn't cope with the emergency braking.

If you value your lives or your family, please don't buy these tires.
