  • Overall - Finishing bottom of the table in nearly every test secured the Accelera its last place, however EVO noted it wasn't as bad as some of the other budgets tested in previous years. As is the norm with budget tires, it was capable in the dry but lacked grip, composure and safety when the surface changed to wet.

    Questions and Answers for the Accelera PHI

    2016-06-26 - Are the Accelera PHI tires run flat?

    We're not currently aware of a runflat version of the Accelera PHI tire.

    2016-08-24 - What side is the front of the tire?

    The PHI will have "outside" written on the outside, or front, of the tire.

    2016-10-18 - What is the estimated mileage for the Accelera PHI 225/45 R18? I have a Kia Soul Exclaim (2011) and am looking for four new tires

    The mileage of the Accelera PHI depends largely on your car and driving style. It's best to look at other reviews posted to match your driving style and vehicle.

    2021-05-03 - I recently purchased a 2019 Nissan Sentra equiped wiht 205 55r16 accelera tires. Approaching 70 miles p/h the care experiences a significant and uncomfortable vibration. Do you have some suggestion to make for this issue?, could it have something to do with the tires itself?

    There is a chance the tire could be out of shape, but it's more likely to be a wheel out of balance. I would suggest getting the wheels balanced at a local tire garage, and while they're balancing the wheels they can also inspect the tires.

    Given 67% while driving a Opel insignia (245/45 R18 W) on mostly country roads for 20 average miles
    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.

    I switched to Accelera PHi from Hankook Vensus purely on budget, prior to that i had the Bridgestone Potenza R003 in 18 inch tire. The Accelera performed reasonable, considering I do 800km per week. it is definitly a hard compound tire and the noise is pronounced at 110km/ph on both concrete and bituman roads. all up 30,000km got out of them, that is 5-10k kilometers better than Bridgestone and Hankook.

    For the price this is a good tire. In the dry grip is equivalent premium brands, however the lack of feedback and occasional slides in the wet do not encourage you to push your luck in the rain/standing water. I believe in a magazine test the tire showed inferior (longer) braking distances in the wet but it is very difficult to tell this in reality.

    For the average driver these are adequate and at the price they are good value.

    The rubber must be quite a hard compound as tire wear has been slow.

    Latest Accelera PHI Reviews

    Given 53% while driving a BMW m2 (265/35 R19) on a combination of roads for 10,000 spirited miles
    You can find a lot of reviews online about these tires, and most of them extremely criticize the performance in various conditions. I switched to Acceleras due to the fact I'll be changing wheels from 19'' stock to 18'' APEX SM-10. As the rear tires were running low, I decided to spend £70 per tire instead of £300+ for Michelins when I'll need to replace them in 6 months anyway to accommodate the wheel change. Considering that I still use Cup2's at the front axle, the Acceleras deal with everyday driving ok. The dry grip is about 30-40% lower than Michelin's depending on the surface of the road, it doesn't bother me as I'm used to cars that feel a bit more alive and most people will not notice the difference until you need to pull out from the side road or get on the busy roundabout. Motorway - is a bit sketchy, the car does not feel as solid or planted at speed when changing lanes, and I'm not talking about going supersonic... that from 60mph+. Definitely will not be able to switch lanes aggressively or the back will swing around you. Wet grip - now this is really subjective, as we all do different driving. Personally, I use my car every day and commute from M25 J16 to M1 J10. M25 in the rain is sometimes scary and I'm sooo grateful I kept the Cup2's at the front. The Acceleras like to skid a bit when going over paddles, same in town, the car will struggle to accelerate even in a higher gear. I'll bring one example, I was overtaking on M25, going 60mph, 6th gear, put my foot down to overtake, and the rear goes. That's partially due to the M2's torque but you get the point... Had a chance to use them during my latest road trip to the lake district, snowy/icy road is definitely something you MUST avoid if using these tires. I was sliding at 3-5 miles per hour with no throttle applied. Managed to get to the top of the Honister Pass, but trust me when I say a little bit of poo came out... The tire is fairly controllable at the limit and beyond, just be aware - you'll get to the limit much much sooner than you think, you can push it a bit, not as much as you would with a £300+ tire but this characteristic lets you have some fun at lower speeds, and you'll not feel sorry shredding this budget rubber as they're soo cheap to replace. In terms of wear, they cope quite well, used them for around 5 months (10 000miles of commuting including 2 road trips to Lake District) and the latest MOT shows around 5.2mm. I can't speak for comfort or noise as having good or bad tires in the car with bucket seats, roll-cage etc doesn't make much of a difference. In a conclusion, It's difficult to say if I would recommend them to anyone, but I'm sure they have some application. Highly depends on what is your car and what is your driving style etc. I can't say anything negative as I knew they will not provide as much grip in various conditions, they just worked for me and saved me money. If you have a slower car, and you drive from A to B I think this tire would work well for you. Not going to wear as much and the price is great for what it is. Just be aware of the conditions on the road, wet grip, and most likely massively increased braking distance. For anyone else, more powerful cars, or someone who likes to drive their car a bit more aggressively - please don't buy it unless you have a valid reason behind it... if you need to save money, or just would like to slide a bit on the track without spending a lot on tires, go for it. But everyday use will affect the performance of your car by a significant margin and you will need to be aware of the conditions on the road at all times.

    I really am not sure what the people giving positive reviews of these tires are thinking, but I had four brand new ones for the dealer. I have zero confidence in these tires to deal with anything other than the most mundane driving. Straight line at 30 miles an hour in the dry, you'll be fine. I have found in the wet under even the slightest acceleration the front end is squirming around, cross a road marking or white line and they seem to just aquaplain over it, even if it's dry. When alone in the car I decided to test them out, you need to know what your tires can get you out of and within 1 minute had managed to get the back end out, accelerating out of bend at 10mph. Having just come out of a 2018 C-Class coupe, so far I am not enjoying the BMW driving experience and I can only think this is down to the tires, shockingly bad. With the winter coming up I will be switching these up for something more reliable. Regardless of the drivers saying 'don't race' as if that's a way to make the tires safe - I don't race - you need to know that if you need to accelerate away quickly, brake sharply or need to get yourself out of danger another way, that the tires are going to let you down. Zero confidence in these to do that.

    These were fitted by dealer prior to picking up car as the existing ones failed mot for tread depth. Obviously the dealer went for the cheapest he could get.... Dry performance is ok BUT these tires are downright dangerous in the wet! Spin up when accelerating in 1st, 2nd, 3rd, 4th on a damp road, even when feathering the throttle. Slow speeds on damp roundabouts will see the front understeering terribly. Spend all the time driving in the wet as if driving on ice. Simply dangerous!! So now I'm having to fork out circa £600 for better quality tires despite the current set only having about 5K on them. Never had a tire, budget, intermediate or premium that is this bad... AVOID!!!

    I had these tires on the rear of my 2.7 Boxster when i bought it, And contrary to the smug reviewers re lack of talent plus I'll never understand owning a premium car and putting on budget tires The back end coming round on you at 20 mph on a damp, not wet, but damp roundabout has nothing to do with talent, and all to do with shockingly bad & dangerous tires, and not that great in the dry to be honest. There was no date code on these, so they could have been quite old, they still had 4mm tread, I believe they may have been updated now so I have no experience of this new compound, but safe to say, if you have these older tires, get rid asap before they cause you an injury or worse. Now on trusty PS4's like my last car which I went though 3 sets with many miles of great grip in all weathers.

    Initially I was impressed, that didn’t last long. Wear is average at best and dry grip will never compete with a premium brand but it’s satisfactory. Wet grip however is a different story. If you drive with your kids in the car you don’t want these tires, wet stopping distance is horrendous. And the final straw was when my car developed a lot of wheel wobble the investigation found one of my tires after less than 2000 miles (3000km) was out of shape meaning the wheel could not be balanced and vibration unavoidable. Fuel economy was aldosterone down around 10%. I’m now back on Michelin all round and the car is transformed.

    Given 80% while driving a Tesla Model 3 Performance (225/45 R17) on mostly motorways for 1,000 average miles
    After 25k with the factory Michelin PS4s (very good tire eight until the end but chuffing pricey) I switched to acceleras after a good experience on my previous car, an E61 530d. The tires last a long time and contrary to opinion do not throw the car into a ditch. I suspect this has more to do with driver talent and awareness of risk. Their wet performance is certainly not as good as a premium tire but then I increase my spacing in the wet. Within days of the new set of tires we had a bit of snow. Although not a winter tire (it has all season written on the sidewall) and moderate braking/acceleration could break traction, they we fine and the tires combined with all wheel drive allowed me to gently make progress up hills when others where spearing off the road. The public road is not a race track and I wonder what many are asking of their tires. Personally I'd go for the acceleras and invest the saving in an advanced course. Better observation will significantly out break the better premium tire. As an example a famous motor industry presenter wrote off his pride and joy 911. The blame was apparently with the idiot that chose a bend to make a three point turn however track driving techniques don't require you to be able to stop within the distance you can see. Stories aside, these tires look good, perform adequately and at £41 a corner, they are awesome

    Absolutely abysmal tires. Complete trap in dry or wet. I purchased a Mercedes CLS with these already fitted. Someone obviously didn't value their life or their passengers! Don't scrimp on tires or safety folks! It's the first and last thing between you and the tarmac! First found out how bad these were with a wet road, sleet conditions doing 70 with kick down. The rear end gave way and car veered left,then right - just managed to correct and regain control or Have No doubt I would be mincemeat. First thing I did was take this off and put Michelin Pilots on!

Having read the tire reviews I was expecting the worst but no,I have nothing so far negative to say about them. Grip is not an issue, handling and feedback, wear and comfort in a working truck well you are not going to achieve this at all. So yes I will buy again and be happy to do so, absolute bargain.
