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.

Top 3 Maxxis Supermaxx ST Reviews

Given 54% while driving a KTM 790 Duke (180/55 R17) on a combination of roads for 3,100 spirited miles
Dry Grip - really impressive for the price point. Never any drama and very consistent grip all the way to the edge of the tire.

Wet Grip - again, incredible for the price. Great feel of grip levels and never sliding all over the place for as long as you're sensible with that right wrist.

Road Feedback - while the road feedback was great in the wet due to the low grip threshold, this completely changed in the dry. Whilst I had a rough idea what was going on, it was never a feeling of complete security especially when pushing the tire. While grip levels to the edge of the tire was never an issue, feel was. It almost felt like you would hit a barrier where the tire would just stop communicating what the front end is doing, leaving to a constant feeling mid corner of "oh sh*t am I about to lose the front?" For proper spirited riding on the road, this can be almost scary at times.

Handling - while the handling wasn't bad, it also wasn't great. Tip in was incredibly sluggish, and this is what makes it lose points big time. Once it is tipped in, mid corner adjustments are easy and actually quick pleasant, but quickly flicking back and forth on these tires feels like more of a workout rather than fun. I find that a real shame.

Wear - the worst point of this tire, and downright embarrassing for how Maxxis advertise it. A sport-touring tire, that gets mileage as if it were a hypersport tire, terrible. While sure it has a lot of grip for what is a sport-touring tire, I'm 3100 miles in and at the rear it's at the wear bars and it is incredibly squared off. When much nicer (but also far more expensive) hypersport tires get similar mileage whilst also being far far more enjoyable to ride, I seriously expect better. Not only that but at this point of wear levels, the poor road feedback only gets worse. The front is still doing alright though, it seems like the typical 2x rear for every 1x front.

Comfort - actually quite a strong point of this tire, it feels wonderfully comfortable over harsh bumps given its decent mid corner support.

Buy Again - absolutely not, while the £175 price for a pair of 120/70/17 180/55/17 tires is great, you can also get Maxxis' Supermaxx Sport MA-SP tires for the same price, which are a far more sporty offering whilst having a duel compound tread, likely leading to even better performance at the same sort of mileage. However, for just £100 more or even less if you can get a good deal, you can find the likes of Metzeler M9-RR's or Pirelli Diablo Rosso 3's. Far better tires which will also should get you more miles both front and rear. I've personally (now that I have worn out the rear) picked up a cracking deal on a pair of Avon 3D Ultra Evo's for just £175, I'm not even going to bother saving some money and buying another rear to make the most out of the front tire, I really feel these Maxxis tires are spoiling my bikes handling.

Given 79% while driving a (225/45 R17) on track for 2,000 average miles
i had these fitted two years ago due to the appeal of the cost. although i don't typically do much mileage on my Gsxr these have been used for commuting, weekend rides and occasional track use first impressions was the more sporty nature of the profile for a sports touring tire, they seem to hold up well even on a wet novice trackday at Outlon park. i believe these were the original choice of tire for the Chris Walker track school and its easy to see why as these seem to offer good consistent grip in all conditions. the only downside is they seem to take time to generate heat. in terms of wear im roughly 2,000 miles into these and wear seems consistent (however as mentioned i do a lot of novice track days on these)

Given 76% while driving a Triumph Sprint RS (180/55 R17 W) on mostly country roads for 5,000 spirited miles
This was my second st of Maxxis St. After the last set I was going to buy something more premium, but I was skint; and these only cost £130 a set.. If anything my opinion of these tires is even better than the first set, Grip and handling at this price, or anywhere under £200 is unbeatable. These were fitted to the review bikes at the launch of the KTM 790, and non of those hacks had anything bad to say about these tires, despite some initial reservations. They are honestly the best tires I have ever used in the wet that are not just purely wet focused. They were developed with the assistance of BSB legend Chris Walker, and he did a great job. However, they are only a single compound tire, and they wear like buggery. My bike has just got an MOT advisory for the rear after less than 5000. You can tell they are a soft compound by the tearing on the edges after any enthusiastic cornering ;-) I would highly recommend these tire if you don't do a high mileage, and ride anything under 130HP I am going to try Avon ST, next.

BMW R1200RT (190/55 R17) on a combination of roads for 3,000 spirited miles
Like most riders, if I was loaded I would have replaced the excellent Michelins on my GTR1400, not loaded, I found a YouTube video with (I think) Chris Walker and his mates testing the ST tires on a circuit on several bikes, including an equally heavy / powerful ZZR1400. Well these guys tried their best to get the bikes moving, and regardless of what they did, the tires held up. The following day journalists who were at the track to the bikes on the roads with the used tires, they loved them too. I invested £130 in a pair, scrubbed them in, and on Scottish Highland roads (where I now live) pushed them more and more to see if I done the right thing or sell them off and go back to the dealer tires. Shouldn't have doubted myself, great in the dry and equally confidence 'making progress' in the wet. All I can say is blòody great tires and will put a pair on my new bike R1200RT for my NC500 in under 24hrs in June 2021. Definitely money well spent.

Good in the dry, wears very quickly in the centre for a sports touring tire. As soon as it squares off its horrible picking up any imperfections on the road. In the wet absolutely no feel & if it's cold as well the front slips, rear slides & if neither of these are happening the you've no idea what they're doing. They're cheap but cheap doesn't make up for how they feel in the wet

Standard Oe tires on ktm 790 duke works well once the heats in the tire and between 12-20 works best have had them break traction a few times. Super hard carcass tread pattern old tech. Wear rate looks quick. Will switch over asap

Decent tire in warm weather, gives you good feel and feedback when there are nice and warm. Tends to step out on me in colder weather and made me lose a lot confidence in the tires. Got 3500miles on the back and it's almost done for, tire wear could be a lot better! There better tires price/quality wise on the market in my opinion.

Given 100% while driving a Suzuki GSF 650N (160/60 R16) on mostly country roads for 1,000 average miles
I bought these tires to test them.
Th tires are excellent with very very good hangling. These are more sport tires than touring tires. The curving and leaning are more natural and easy than with my old Bridgestone bt 20.
In wet condition the tires are perfect. They are very soft and have excellent grip. I expect to last enough (10 - 15 K) is good for me. I prefer new tires more often.

Given 70% while driving a Triumph Sprint RS (180/55 R17 W) on mostly country roads for 5,000 spirited miles
These are very stiff tires, and quite hard to fit by hand. Once bedded in they are superb on the road, very precise and grippy. They are far superior in the dry to Michelin PR 3, and at least as good in the wet , and at less than £130 a pair they should be my first choice for replacement. Unfortunately the rear is squared off and almost down to the wear bars at less than 5K despite avoiding motorways. Like someone else says a 2CT version is needed to make these a serious touring tire. If you can get them cheap and don't do a huge milage they are recommended. And don't rule them out for novice trackday use.

Given 63% while driving a Kawasaki ER6F (160/60 R17 W) on mostly motorways for 5,500 spirited miles
These Tire's offer plenty of grip in the dry and aren't to shabby in the wet either. I commute all year round on mainly dual carriage ways so the middle of the Tire takes a hammering. My only gripe with this Tire is its not dual compound. I've manged just 5500 miles out of the rear and its shot, if I compare it to my last Tire a Bridgestone BT023 which is dual compound I got 10,000 miles out of the rear.

I fitted these Tire's as a bit of the an experiment to see if the budget sports touring Tire could compete with the big boys , Unfortunately in my case with the type of riding I do it doesn't, it's false economy for me to go for a cheaper Tire, half the mileage but not half the cost. If spend a few quid more upfront and get almost double the mileage its dual compound all the way for me!

Good tire but as I say Maxxis would need to bring out a dual compound sports touring tires if I was to consider fitting them again.

Given 54% while driving a Ducati St4s (120/70 R17) on mostly country roads for 4,000 average miles
After 4000 miles it has gone out of shape and rubbing on the front mudguard with 2mm of tread left. Very poor.

After reading review I thought I would give them a go. Bought a pair from MyTires at a very good price and fitted them myself. First impressions were very good, smooth and good stability but after only 1,800 miles I noticed the rear was well worn and now after 2,100 miles it is down to the legal limit of 1.6mm and this is supposed to be a sport touring tire! I don`t think so.
