The Tyre Reviews Score is the most comprehensive tyre 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 tyre 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.

(160/45 R17) on mostly motorways for 18,000 average miles
Hi I'm a 100 mile a day commuter that breaks down to 70 miles motorway and fast A roads around a constant 80 mph and 30 miles a day through London 20mph
If I'm lucky I currently ride a er6 but had these on my 600 hornet they are a great all round tyre last for ages the ones on my er6 have done 17000 miles so far and there's still life in them they haven't squared off too much I'll probably change them at 20000 or there about a the stock tyres that came with the bike were rubbish handling and were worn out in 8000 miles these Avons are the business take it from me ( someone who actually rides their bike)

Latest Avon Storm 2 Ultra Reviews

Given 66% while driving a Honda CBR1100XX (225/45 R17) on a combination of roads for 3,000 spirited miles
Felt compelled to comment on these tyres as i bought a pair based on the rave reviews on here about all round grip & particularly about how long they last. Ivehota honda blackbird which these tyres were also recommended for so igave them a go. I have ran lots of other sports touring tyres & usually get around 4500mls from a rear & thats a mixture of pillion, loaded with luggage & jyst solo riding. I taken with the reports of the longevity of these tyres as im always after more miles so i gave them a go. I agree with most reviews & i found the dry & wet grip very very good & the bike always felt poised & keen as the triple compound wears the tyre evenly so it tetsins its roind profile rather than the flat middle section you get on most tyres when they start to wear in the middle, those are the possitives & all very good. On to then a najor negative & i haveyo say a real dissapointment! I ride progressively & the rear gets used edge to edge & the power put through all areas of the tyre, it lasted less than 3000mls ?!?!? Thats shocking given the hype of 8000 plus miles by sone reviews. Thats also been mostly 1 up with no luggage on this tyre. Thats shocking, ive hot more miles than that out of pure sports tyres. If you coast along & dont put much power throug it then it will last longer but i sippose any tyre would. So in conclusion yes theyre good but theyre cheap for a reason, they dont last 5 minutes which for a touring tyre is pants, sports tyres will give you much more grip & last about the same miles but if your after more miles spend more money on a set of michelin pilot roads or metzler Z8's same grip & stanility but twice the milage. Conclusion, initialy really good but very very poor distance for a so called touring tyre. I wont be buying them again

Given 83% while driving a Suzuki Bandit 1250 SA (180/55 R17 W) on a combination of roads for 10,000 average miles
Own a bandit 1250. used mainly long summer tours when all mileage is put on. I replaced worn out Dunlops at a mere 4000 miles in 2013. Put on Avon Storms. lasted until now (June 15) and 10,000 miles later. That is 3 European tours and my return recently from Italian Lakes and alps. Just purchased another set, Ultra 2 that should be even better. I reckon almost £100 cheaper than Pilot Roads that tempted me. As an all purpose sports touring tyre worth a punt. You can get a pair or well under £150 as I did !

Given 100% while driving a Kawasaki ZZR1200 (180/55 R17) on a combination of roads for 4,000 average miles
Owned this bike for 5 years, tried all sorts of tyres, Avon storm 2 ultra is simply the best all round tyre.

I ride Yamaha xjr1300 and have used these tyres for the past five years going through two rear and one front tyre a year - give great road feedback great in the wet and don't think ill change from Avon storm any time soon -

Given 77% while driving a Kawasaki ZX6R (170/60 R17 W) on a combination of roads for 12,000 average miles
A lack of grip in the rear in severe rain alerted me to the fact the rear was close to the wear limit. Having checked the mileage the rear had done almost 12000 miles! The front has done 6000 miles and still has life left.

The tyres have served me well on a mixture of commuting and weekend rides. I did lose the front in rain under heavy braking but can I attribute that to the tyre? I don't think I can but how any other tyre may have handled the situation I can't answer. For the price and life these tyre are a good choice for sport touring.

Given 89% while driving a Kawasaki ZZR1400 (190/45 R17) on a combination of roads for 0 average miles
Said I would never buy avon tyres don't now why but I always did,
anyway I bought a zzr1400 two years ago with them on, and I will be replacing them with the same tyre storm ultra 2, how wrong was I,
I am now going to feel like a fool by saying mine have done 12,000 on both, up to now and still going looks like another 2,000 left in them crazy I know,
and I do ride as the zzr14 wants to be ridden hard most of the time, I have had not issue's with the storm 2 in the wet or dry that any other tyre would not have done, recently I have been up and down motorways the rear has squared off, but all tyres do that, I am more than happy with these tyres I tell it as it is and I am no dreamer.

Given 94% while driving a Suzuki GSX 1300 RK4 Hayabusa (190/50 R17 W) on mostly country roads for 8,000 spirited miles
i've had two superblackbirds and now on my 2nd hayabusa, this is the best tyre i've ever had on a bike like this, i tour europe, plus hard cornering and acceleration, nothing else comes close for stability and even wear and longevity, if you don't get on with this tyre, you're riding the bike wrong. love it, excellent road contact and feel, this is one of only a couple of tyres i trust, they even warm up quick, (never trust any tyre until its warmed up) been riding 32 years. now up too 12,000 miles on current pair, expect another 2-3,000 yet, very happy with them

Given 89% while driving a Kawasaki 650 Versys (160/60 R17) on a combination of roads for 6,000 spirited miles
Im on my second set of these tyres now,i was so impressed with the longevity of the first set i had that i decided to go for them again.I weigh 16stone and i got 6000 miles out of the rear,it hadn't really squared off either,it still held its round profile after that mileage but the rubber was past the indicators on the grooves so i renewed.I Could not fault them in any way,in the dry they stick like glue and are very reassuring in the wet,never had and movement at all and ive ridden in a lot of rain this year.

Given 64% while driving a Triumph Sprint Sports (170/85 R17) on a combination of roads for 4,000 spirited miles
Replaced worn out Conti's. Agressive/Spirited riding all year round (within limits!) Toured Ireland last summer - better than the same trip on Conti's in the spring. When new/warm wet grip is ok - non existant in cold British winter, to be fair the Conti's were the same year before - conclusion they only work if warm. Fitted as a pair, just got 4K up on them and puncture in rear - bout 2K left - Looking for something else now, not bad but not great, pricey for an "OK" tyre, not sure which way to go now.

Given 59% while driving a Honda ST1100 Pan European (160/70 R17 V) on mostly country roads for 3,000 spirited miles
I have used these for the last time, the tyres do not suit the St100. The front tyre cause a steering wobble and can become dangerous at times, ie one handed whilst lifting the helmet visor. These initally felt good when compared to the cross ply tyres used previously, but when compared to the competion not that great.
