The Tire Reviews Score is the most comprehensive tire scoring system available. It aggregates professional test data from multiple independent publications, user reviews, and consistency analysis using Bayesian statistical methods, weighted normalisation, and recency-adjusted scoring to produce a single, reliable performance rating.

Methodology & Configuration
Scoring Process
  1. Collect Test Data: Gather results from professional tire tests across multiple publications. Minimum 1 test(s) required.
  2. Normalize Positions: Convert test positions to percentile scores using exponential weighting (factor: 1.2).
  3. Apply Recency Weighting: More recent tests are weighted higher with a decay rate of 0.95.
  4. Incorporate User Reviews: Factor in user review data (minimum 5 reviews). Weight: 15%.
  5. Bayesian Smoothing: Apply Bayesian prior (score: 7, weight: 1.5) to prevent extreme scores with limited data.
  6. Calculate Final Score: Combine all components using normalization factor of 1.1. Max score with limited data: 9.5.

Given 20% while driving a Audi A4 (225/45 R18) on mostly town for 10,000 average miles
I have a very bad experieemcw with these tires. I changed all four tires of my car thinking this will be great choice. But eventually all four failed pre matuarly due to reinforcement damage and loose rubber. I wrote this matter to federal factory as well. But they seems not willing to listen. So my advice is if any one willing to go for federal tires, think twice. One Image of the failed tire attached below.

Very noisy tire. To the point of being irritating.

Given 38% while driving a Toyota MK3 MR2 Roaster (225/45 R17) on a combination of roads for 600 spirited miles
Unstable at highway speed and especially during higher speed cornering. Never lost grip wet or dry, though it felt like the tire itself was made of gooey mush. It was as if some suspension part had come loose. It hadn't. Will never buy again. Swapped them out before 1000 miles. Fortunately was able to get credit toward new meat.

Given 73% while driving a Jaguar xf premium luxury (225/45 R17) on mostly country roads for 3,000 average miles
These tire were fiited on the car when I bought it, so not my choice, but I was pleasantly surprised by how well the car handled and road noise was minimal.

Can't comment on wear as they came off after less than 3000 miles to be swapped for winter rubber, but they've been put in the loft and will definately be going back on next summer. Certainly there is no noticeable wear on them yet and they look like brand new tires still.

Having looked up the price of them, I was expecting them to be truely arwful but was actually quite impressed.

Could not believe how quick the tread wore out on these and will never go for this brand again....also pretty noisy.

Given 59% while driving a Peugeot 206 1.6 xt (195/55 R15 H) on mostly country roads for 333 easy going miles
I accidentaly run over a buss curb in 50km/h so my right front tire blow its steel cords, so they are sticking out on that tire 10mm by 20mm. Law says its illegal so I have to change that but there was no tire in that size anymore, discontinued tire. So I have to go and get two new ones.
8kg tire rubber weight, 330aaa rubber for that size, ranges from 230-340aaa in the sizes

Given 37% while driving a Honda Fit (Jazz) (225/45 R17) on a combination of roads for 28,000 average miles
Fighting like hell to get 28,000 miles out of this tire on a Honda fit.
this tire is virtually a scam, at 20,000 I had a tire separate so bad it was unrunable.Had to buy another Formoza, Schawab only gave me 25%. Now at 28,000 I have steel cords showing on two more tires and the 3rd old tire has a band separating. (shakes at 60 mph) but still trying to get every short changed scammed dollar out of these tires.

Spend Your cash on a better tire...like Yokohama or something don't buy these.

Given 21% while driving a Renault Clio III 1.2 55kW (225/45 R17) on mostly country roads for 5,000 average miles
These are the worst tires I have ever bought, £52 a corner and I have worn them out in 5000 miles, my Continental PC2's lasted me 15k. These Federals are dangerous in the wet even when new with very little grip and in the dry still questionable levels of grip.

Given 54% while driving a Suzuki Swift 1.3l 2007 (185/60 R15 H) on mostly country roads for 10,000 spirited miles
The wear on these tires has been minimal over 10,000 miles suggesting a hard rubber compound that gives reasonable performance in the dry. In the wet, the feedback is good, but unfortunately the tires are telling you that they have minimal grip which translates to significant understeer at relatively low speeds. I would not want to brake hard in the wet and always drive defensively to avoid the possibility. They have M+S stamped on them which used to mean Mud & Snow when I was a lad. I'm not sure what it means now but whilst the tires are ok on fresh snow their performance in slush or on ice is poor. As a budget tire for driving around in the dry they are fine but any hint of wet weather requires a large adjustment in expectation and speed.

Given 66% while driving a Honda CRX Si (195/65 R14) on mostly country roads for 30,000 spirited miles
So I have these on a crx si with a zc swap, exhaust, lightweight flywheel, racing clutch, and an intake, the cars def. Not slow, with that said these tires handle everything I throw at them with this car, I drive tons of miles per day for work in very mountainous conditions, they handle well in dry and wet, not too Much noise that I can tell, I havnt even rotated them yet so the wear is a bit uneven, the fronts still have about 60% tread and the rears have 80%, with 30k hard miles on them. I wouldn't reccomend for someone looking for a higher performance tire, but I'd deffinately reccomend for someone looking for a decent reliable tire.

Given 46% while driving a Mazda 3 Series (215/45 R18 W) on a combination of roads for 10,000 spirited miles
I've now had these tires for just about 6k and because of a puncture, I'm replacing both fronts. Just as well as they're terrible! The dry grip is ok, but there's little feedback to tell you when grip is about to run out - just LOTS of road noise. Wet grip is exciting and care is needed even at low speeds. The real pain is the wear - 6k on the driven wheels and I reckon there's no more than 3mm of tread left. A poor performance from a budget tire. Here's hoping the Falken 452's I've ordered do much better.

Given 70% while driving a Mazda 3 Series (215/45 R18 W) on a combination of roads for 10,000 average miles
It's early days since I put these on the front of my Mazda 3MPS so there are things I haven't offered an opinion on just yet. In general, the tire feels sure-footed, dry or wet, and provides plenty of feel and grip. I haven't pushed too hard yet, so I'll write another review when I have and also offer info on wear etc
