I have now purchased and destroyed 12 of these tires in the same 16" size as I use them for rallycross in Texas. These tires normally last 18-20 laps and are great before they come apart. You pay a good price for a tire that lasts only as long as you want it to. Now, I also run the 651 Sport and those also wore down fast at the track a little too fast. I do run Toyo Prox R888R and those seem to last a little bit longer, but are 3x the price!
I have no idea how these tires work on public roads, but I have done drift and rally with them and will continue to....

I'm not sure what everyone is complaining about... These tires work fine.. My car is RWD 270 bhp... No problems... The funny thing is, the Phi's are on the front, I have an even lesser Accelera tire on the back and yet I have no issues, the car is controlled, grips well and the feedback is good. From a stopped launch to pulling quickly out of a side road, I've not had any issues. I haven't had any understeer from the fronts, they communicate well. In the wet and in icy conditions again, no traction issues. They are stable on the motorway no wandering or instability.

The only thing to note is the road noise is a little higher than you'd expect but not a big issue and the ride is a little harsh although I'd expect that from any tire with a 30 profile.

I paid £74 per tire + fitting (£22 per tire), so £182 for two, fitted.... A Michelin of the same size would set me back over £280, per tire, fitted! I'm not expecting these budget tires to grip like a Michelin or similar premium brand and neither should anyone else. I'll save the £380+ for two tires thanks.

These are the worst tires I've driven on in recent years. They were fitted to a seat ibiza my son bought after just passing his test, the dealer thinking he was doing a good turn supplying the car with 2 new front tires. On the front the car understeerd like it was on ice, I genuinely thought I was on a diesel spill the first time I went round a wet roundabout. Awful wet grip and dangerously so for a new driver just coming into winter when the road will mostly be wet. As the car had decent branded tires on the back I thought I'd swap them round even though mixing tires on the driven end of the car is not a great idea, one avon and one toyo were swapped to the front and the accelera tires on the back. Now the car had good traction on the front but even at moderate speeds the lift off oversteer was unpredictable and sudden and a less experienced driver would be all over the place and probably off the road backwards. I had to shell out nearly £170 for 2 decent tires for him as he didn't have the money to get new ones right away. I could not of slept at night knowing my son was driving on these death trap tires.
Just to be clear, I've driven hundreds of cars over 40 years and I would say I'm a hard but not stupid driver, I've had everything from v6 capris to gtr's, I know how to control a car and I can say without question these tires are a false economy, spend the extra 30 quid or whatever on decent tires and save yourself an insurance claim. I read someone's review saying if you drive slow enough they're fine. Well you could argue that if you drive completely slick tires in the rain you'll be fine if you go slow enough. The problem is things happen that are beyond your control, you may need to stop in a hurry for whatever reason and If the car in front of you is on decent rubber and you're on these, trust me, you're hitting the back of them or going off the road.
DONT BUY!!!

No grip ,feel disconnected from the road would never recommend these ditch finders to anyone

Recently fitted 4 of these tires and these are incredibly quiet, above average grip in wet and dry (we had a short spell of rain recently and the car was perfectly stable). These replaced a set of Continental's i had on previously and I'd say the Accelera's are a bargain for what you get.

Absolutely, without doubt the worst tires that I have ever encountered. Pleased to say that I didn't fit them, but they were fitted (brand new) to a car that I bought. Both front tires were below the legal limit within 3 months (3000-4000 miles) of moderate driving. I drive a Kia Sportage auto, so I'm hardly racing about and giving the tires a hard time.

Total junk at best, dangerous at worst.

I bought these online as i had a discount code, and my car had brand new acceleras on the front tires already so bought a matching rear set. I had just bought the car, and it needed some rears, so instead of going for premium which would have been 4 times the price per tire at this size, i bought these, as i didn't fully trust the car at the time, and didn't want to spend £1k on tires just yet. I've had good experiences with budgets before, so not afraid to try them. In the dry they are absolutely fine, a little noisy, ride is quite firm on the tires, but i don't mind that. The tires state all season on the side, although most reviews treat them as a summer tire, and the tread pattern looks like a traditional summer tire to me.
Wet weather performance is where this tire struggles, wet weather braking being the only noticeable downside, initial bite in the wet upon braking is not very strong, and just takes that little longer than you'd expect. So factor that in.
As i mentioned the ride is firm on these tires, and the grip not the highest, so that would suggest that the tires are of a very hard compound which should last a long time.
For the money they're good, and for most applications i would say they're fine. They look and feel like a very robust tire aimed at longevity rather than peak grip, i think the bad reviews here are by FWD hatchbacks that drive them hard, which is just not what they're for.

One of the worst tire which i hv seen frm my age 17 to 37 years , in just 3600 km my car tire got slapped and bcm a healthy airy shapeshop vendor or Retialer or Tire Showroom Owner said this s out of warranty because this s Cinese tire but on this ISI maark is there, no warranty guarranty , i hv 6 cars so i will not prefer this tire to anyone

I have only 145 miles on these tires but I had comfort while driving and road noise was little to none.I pushed them to triple digits in the dry and wet and they felt solid.Other than a slight vibration which I suspect wheel balancing could be better, but the tires are decent for the price.

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 on the car when I bought it. I do NOT recommend these tires. Not great in dry weather and downright dangerous in the wet (which is quite often in the UK!) Cant get new tires quick enough

DON'T buy these tires. Worst experience ever - not worth it. Dangerous in wet and zero comfort.

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.
