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.

Questions and Answers for the Firestone TZ300

Ask a question
October 20, 2016

In the tire reviews is it better to have a wear value higher or lower? The wear percentage value means the tire will wear faster as long as the value is higher?

The lower the value, the worst the wear. 1% would be the worst experience with wear, 100% would be excellent wear.

Given 61% while driving a Opel insignia (225/45 R17) on a combination of roads for 8,500 average miles
Have it on Opel Insignia. Good tire in a dry condition but in wet and rain is really bad. Braking catastrofic, be very carefull. A little bit noisy but confortable. M.

Given 63% while driving a Hyundai Coupe 2.0L (225/45 R17) on mostly country roads for 0 average miles
Just replaced my old Michelin tires for these on my Hyundai Coupe. The tires or good, not brilliant but just good. I find cornering is ok, although when pushed they can be slightly unpredictable when compared to my last tires. There was a big noticeable difference here. My main criticism is straight line speed where they become quite didgety and to be honest quite scary. Steering goes very light over 85mph, and this is not down to my suspension set up as the previous tires didn't do this. Overall a comfort tire rather than a sport tire but thats what they are being marketed as. I might change them over next year back to Micheline or Vredestein tires if i keep the car.

Given 59% while driving a Ford Focus MK3 (205/55 R16) on a combination of roads for 16,000 easy going miles
not sure what most of the categories mean when trying to mark the tires but just want to add my feelings regarding wear .... mine have lasted only 16,000 and im no Nigel Mansel !

Just wondered if I should have gone back to Firestone and report this meager mileage ?

Given 77% while driving a Ford Fiesta (195/50 R15 V) on a combination of roads for 10,000 spirited miles
Very good overall tire, Very good dry grip as well as in the wet, only loses grip in the wet when really pushed.

Not bad for road feedback but in my opinion not as good as previous Kuhmos

Wear is good though, done 10k on them so far and only about half worn

Given 86% while driving a Skoda Octavia (205/60 R15) on mostly country roads for 5,000 spirited miles
Marks given are relative to the OE Dunlop tires that have been on the car since new. I was never really comfortable with the OE Dunlop 2000's but I migrated to the Dunlop 200's to keep consistency with a view to exchanging after 3 years. As it turned out, we kept the car so when the time came I looked for something better. I used this site to cross reference good reviews vs what the local garages were stocking and I picked the Firestones. Well, they are soooo much better. I live in Scotland so it is all twisty-turny A-Roads with the odd down-pour to deal with. Firestones ace the Dunlops in every respect. They make driving the car fun. And when my other mode of transport is a 1200cc motorbike, that's high praise indeed.

Given 56% while driving a Renault 19 (185/60 R14 H) on a combination of roads for 6,500 average miles
Good tire in the dry and average in the wet.
In summer days when the tarmac is hot the tires are very noisy and start to loose grip which leads to understeer in sharp corners or roundabouts.
The front ones are wearing even but a little faster than expected.

Given 84% while driving a Alfa Romeo 156 2.4 JTD mjet (225/45 R17) on mostly motorways for 18,000 spirited miles
Alfa 156 2.4 20v. With it's very heavy engine (and my "keen" driving probably) it's incredibly hard on front tires. T1Rs did about 12k, Sportrac 3 managed 10k (!). I tried the Firestones through needing something a bit longer lasting, expecting to have to compromise on grip. Nope!

Really really good tires for the price. Quiet, good firm sidewalls so positive handling when pushing on, almost as good in the wet as in the dry and have managed 18k on the fronts! The rears have loads in em yet.

I've just decided to put another pair on as I can't find anything to suggest another similar priced tire would be any better.

One caveat - they're not that good in the snow due to the channelled tread design. There are no blocks to "bite in". The Toyo T1Rs I had were superb in snow, if not so hot the rest of the time....

Given 80% while driving a Vauxhall Astra (185/65 R15 R) on a combination of roads for 129 average miles
2003 Astra fitted with Firehawk from new. I'm not a speed merchant but usually 80 + on good roads. Replaced front tires at 45,000 with equivalent Firestone in 2006! Replaced all round at 87,317 miles with TZ300 88H in Feb 09! now replacing front again at 129,000! can anyone beat that? Poor road surfaces now make more road noise.

Given 70% while driving a Ford Puma 1.7 (225/45 R17) on a combination of roads for 20,000 spirited miles
Good tire to start with, have these fitted to my 1.7 Puma but they are not wearing well. Not even done 20,000 miles. Yes I dont hang around, I dont wheel spin though! Other tires have lasted much longer. If you dont mind changing tryes sooner rather than later then for the price they arent a bad option.

Given 70% while driving a Toyota Avensis (205/55 R16 W) on a combination of roads for 15,000 easy going miles
Driven 15k on these Firestones on my Toyota Avensis. Although it's not used up yet, the fronts are wearing a lot faster than I'd have expected at this point (yes tracking alignment has been checked, and wear is even). They do seem to behave very well at least.

Given 100% while driving a Opel Zafira TDCI (225/45 R17) on mostly motorways for 50,000 average miles
Amazing tires for the price. I have used every brand of tires, no one is so silent. Amazing in wet and dry roads. I advise to buy with no fears.

Given 30% while driving a Peugeot 407Hdi (215/55 R17) on a combination of roads for 2,000 average miles
These have got to be the worst tires I have ever had. The road noise is terrible. It sounds like there is a motorbike without a silencer sitting on my rear bumper. Had them 3 months and going back to Pirelli P7's.

Given 84% while driving a Mazda MX5 (225/45 R17) on mostly country roads for 8,000 spirited miles
Whilst not having a charismatic name these are an excellent mid range buy. Price good and good value for the money. Performance perfectly good for normal and spirited road use. Not tried on track so cannot speak for them there.

Given 86% while driving a Rover 214 Si (195/50 R15) on mostly motorways for 800 average miles
Brilliant tires.

Installed a full set of 4 tires the morning before a trip down to Newquay, Cornwall (250ish miles from Birmingham).

I'll be breif: Extremely quite. Extremely 'sticky' (good grip). After 800 miles (after getting home) they barely look used.

They do seem to help eat up the petrol though.

Would definately recommend.

These have been rubbish on our Golf, put a new one on the rear after a flat, the other tires same make TZ200, have done 8K on top of the TZ300 and its BALD...crap tire, will not recommend or buy again less than 10K on school runs, wife only does 8K a year mileage...rears going bald before the fronts - totally un heard of.
