Review Summary
Based on 157 user reviews
Drivers' experiences with the Accelera PHI are highly mixed, but the dominant theme is very weak wet performance. Many budget-focused users report acceptable dry grip, stable motorway manners, decent comfort/noise, and surprisingly good tread life for everyday or steady driving. However, a large number of reviewers describe poor wet grip, long braking distances, and unpredictable handling in rain-often labeling the tyre unsafe on more powerful cars or in aggressive use. Overall value is praised, but wet-weather limitations are a major concern.
Strengths
- Low price/value
- Decent dry grip for everyday driving
- Long tread life for motorway/steady use
- Quiet/comfortable ride for some
Areas for Improvement
- Very poor wet grip and long wet braking distances
- Unpredictable handling in rain (oversteer/understeer)
- Aquaplaning and loss of traction at modest speeds

Latest Accelera PHI Reviews
Marketed as a "Budget, dry weather, performance tyre". Well, there is one word that I can use to describe them. DANGEROUS!
First thing I noticed was the weight of them and how "floppy" the rubber was. I've used rubber bands that feel more robust than these tyres. You can comfortably carry them with your little finger and I honestly think that you could turn them inside out without too much effort.
Fitted to the car, I will admit that in the height of summer when the road surface is well into the 40 degrees, the tyres performed OK. That being said, there is little to no feedback from the front axle but you can train your brain to over ride the uncertainty and blindly trust that you will have the grip. Its a concerning feeling but the grip seems to be there in most situations (if its a very hot day). The low speed feel of the tyres is poor, steering feels spongy when negotiating a parking space for example. You can sense the tyres side walls squishing and moving about as if you had a bouncy castle wrapped around your wheels.
Cooler weather is where these tyres become utterly perilous! I got the car out early this year and went for a blast yesterday. 12-15 degrees out but dry and sunny. We went for a blast down some epic B roads that I know well and I have driven down them in haste many times. These tyres almost killed us. The braking performance is absolutely shocking. We had just been through a twisty section, we'd been driving spiritedly for about 20-30 minutes so the tyres should have had plenty of temperature in them. The final long straight down to a tight right hander, I felt confident in the cars ability so I pushed it a little more than I normally would be nothing crazy. I hard braked, in a straight line, while rev matching down shifts, prior to the corner which resulted in a sudden and total loss of traction on the front axle. Thankfully there was a tarmac farm drive ahead so I had somewhere to run off. I could not believe the distance that it took to bring the car to a stop. I was just a passenger at that point. Cadence braking brought nothing to the party, it was like hitting black ice. Now this car has just had an MOT, a 4 wheel hunter alignment, all of the bushes and suspension components checked over and tyre pressures exactly as specified by Porsche. The only thing that could have caused this is the tyres.
Its not the first time that this has happened either. Last year, in the height of summer I was about to miss a turning and thought, "its ok, I can scrub enough speed off and make the turn", there was nothing behind so I hit the brakes hard. The front axle lost grip and we slid straight passed the turning. At the time, I thought I was just being over ambitious but now I think that these tyres are just outright dangerous.
I've never driven the car in the wet so I can't comment on wet weather performance but if this is anything to go by, I can only imagine that they are lethal. I honestly don't know how they are allowed to be sold in the UK. They literally cant perform their primary function.
Do not buy these tyres if you value your life. Certainly, do not buy these tyres if there is even the slightest chance of having to drive in the cold or wet.
I will be removing them and throwing them in the bin before this car turns another wheel.
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 tyre with a 30 profile.
I paid £74 per tyre + fitting (£22 per tyre), so £182 for two, fitted.... A Michelin of the same size would set me back over £280, per tyre, fitted! I'm not expecting these budget tyres to grip like a Michelin or similar premium brand and neither should anyone else. I'll save the £380+ for two tyres thanks.
Wet weather performance is where this tyre 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 tyres, and the grip not the highest, so that would suggest that the tyres 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 tyre 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.
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 tyres are a false economy, spend the extra 30 quid or whatever on decent tyres 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 tyres 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!!!
I have no idea how these tires work on public roads, but I have done drift and rally with them and will continue to....
