ACCELERA 651 SPORT XL BSW

In size 225/40 (r18), their tread width is comparable to other makers ~205. Well, does it matter? Yes, in the sense that when you install them onto an 8.5 wide rim, you'll notice that you're stretching the fit, and the sweating starts. Installing a tire alone with a basic tire machine is no longer possible. If I had known this, I would have happily gone for at least 235 wide so MAYBE they would match the 215-225 tires from other manufacturers. I have the tw100 model, if that matters.

As with all things each of us has different experiences. I bought these Accelera 651 Sports as the price was great. They went on my Mini Cooper S, 2006. Initially I thought they were very good. I bought them in January 2024 in the cold weather and they performed very well. The DOT put them at November 2023 so was happy there too.
Jump to 6 months later and they started to feel a little spongey. They were wearing quite a bit, I think they are a soft compound so fair enough but I was definitely not getting the handling I first had. Turn-in was slower. Once turned it kind of felt like the car moves a little and then grips. Jump to the next winter and the grip had disappeared to a frightening level in the cold. I get it's a summer tyre but it was way better the previous Jan. Very slippy. Especially as I'm FWD. When my MOT came up the following January. Tyres 12 months old and about 6300 miles, 14 from DOT I had advisories for the rubber perishing on all 4 tyres. On looking myself I could really see it. That's 12 months and done. I won't personally buy these again. Maybe if you're going to the track and want something cheap to wear out in a day.
I've now just put 4 Eagle F1 Ass 6 on so fingers crossed.

The Accelera 651 Sport is marketed as an All-Around multipurpose semi-slick; capable of enduring the demands of performance driving while also providing good road manners. I did not find this to be the case.
This review comes after having had two sets of these tyres(2k miles each) in their 200 Treadwear compound fitted to my 290hp big turbo Abarth 500; each time only enduring one trackday before being rendered useless. Tyre temperatures were monitored and pressures were set to 30PSI hot, front and rear for trackdays. 30PSI cold for road use.
Dry grip was comparable to a budget road tyre, non-existent and inconsistent. On track they displayed a significant oversteer bias with inconsistent front axle grip and really rather soft sidewalls for a semi-slick. The surface of the tyres wore quite heavily on the inside edge, suggesting they are not suited to aggressive front end alignments in "grip" use, front axle camber was set to -3.5 degrees, backed off to -1.7 after multiple laps. Rear axle camber was -0.5, rear tyres wore reasonably evenly.
In the wet these tyres offer about 70% of the grip they have in the dry, suggesting the tread pattern is really rather good at evacuating water and the compound is not too terribly temperature sensitive.
Speaking of temperature, these tyres withstood multiple heat cycles with no real drop in performance over their lifespan, so(as suggested by the website) would probably make very good rear axle tyres for high power drift cars. Minimal feathering was observed by the end of each trackday.
On the road, these were extremely noisy(even more so than any other track tyre I've ever used), wore at an accelerated rate, were very squirrely in the wet at 50% and below tread depth and despite having soft sidewalls for track use were extremely stiff on the road.
I would recommend the 651 Sport if you are needing an *extremely* affordable semi-slick on the rear axle of a front wheel drive track car or are trying to encourage oversteer in a FWD track car. Otherwise, you would be better served by the Nankang NS2R 180TW tyre in similar sizing which has longer life, better grip, better feedback, is less sensitive to aggressive geometry and has similar heat management.

Bought these after switching from a Miata. I didn't want to spend $800+ on autocross tires, and knew some people who ran these at autocross.
In the dry, these tires grip. Hard to say objectively, since I haven't had any other 200TW tires on the E46 but these tires out gripped my NB Miata on Falken RT660s (measured by speedometer around the same 4 leaf clover). I felt that they handled both fun road driving and autocross very well.
In the wet, these things love to hydroplane. If you get into any standing water, slow down. Though, that's kind of expected with the cheaper 200TW (had similar problems on a set of GT Radial SX2s) segment. I never had these problems on my Falkens (admittedly they were 50mm narrower).
Tire wear was also not great, but I suspect that was partially due to my alignment settings.
They are much louder than my winter tires on the same car, but not a deal breaker for cheap 200TW tires.
For the price, I don't think you're going to beat these. Grip way better than my old GT Radials, and are dirt cheap. Unless you're ultra competitive in your class, I say go for them.

I have used these tires now for about 2 years now. I was worried at first as I'm NOT a huge fan of trialing out tires from what I know works! I tried NS2R's and they were rubbish in light cold mornings and nearly crashed as they slipped out on me after a 30 mile drive! so those went and will NEVER get touched again!
Im a die hard Vredestein fan, from the sessanta's to the vorti's they do it all inc track days but do have limits on track days! its my go to tire for road use ALWAYS!!!
So after some heavy reading and reviews I decided to trial these 651 sports out for summer. when I got them on and they got worn in I liked what i was feeling with the stiff sidewall and response was great. I was mostly using them for my track wheels but on the roads so I knew what to expect from them.
Dry handling is epic! they handle well and grip like you want them to, there is no moving of the tires sidewall so everything is direct and precise.
Wet handling is also pretty good to be fair, IT DOES HATE standing water! but what track tire don't! they can handle well in the rain and once i got over my fear for my first wet drive they really shocked me as to how well they grip in the wet and brake under real hard testing without being able to lock them up much, you will see some cornering grip loss of course. if you go over 80mph they can float a bit on the water surface if its raining hard. light rain seems to not bother them really
I generally get 1, 9 month use out of the fronts ( 10k miles ish ) and then i can re use the rears next year BUT they do crack easily the following year you use them so you will possibly not get 2 full years from them without replacing them sooner, that's the ONLY downside really for the price. I swap rears to front the next year and then replace after a few months for new ones and then the rears to the front again and so on and so on.
it works out cheaper to buy good road tires for 2 - 4 years vs buying these for normal road use over 2 years. so bare this in mind!
But since this is a track tire you likely will need it for 1 year and that's all if you get them to last.
I find these do follow road gaps more then normal tires but that's ok and just keep hands on the wheel more.
I would and do buy these again and again each year for my non OEM wheels i run most of summer time. its a great tire to run and use and you really wont be disappointed in them. Wait for sales if you can as they do 20-30% sometimes off the tires which is nice and makes them even more of great value to run
