The BEST TIRE for your Brompton.

Brilliant video. There are discussions about the adverse effects of too high a pressure - energy loss due to vibrations induced by the road irregularities. I run my Marathons at the lower end of recommended pressure. Cheers

[@2Bikes4Adventure]

@oe59 ,you are totally right. Depending on road surface, you can reach a point where higher tyre pressure just creates more vibration and starts having a detrimental effect on overall rolling resistance. The optimum pressure (which varies according to surface and load) is that “sweet spot” we are all looking for. This could make an interesting follow-up video: Ideal Brompton tyre pressure

I drive also a Brompton with Kojak tires without puncture. There is one tire from Schwalbe missing: The Schwalbe Winter tires with spikes. I've been using them now for two seasons and they are worth mounting if roads are often covered with ice.

you are right, I used this video to justify my continental purchase but London roads are just full of shitheads who throws glass on the streets, 3 day new continental got punctured by glass. and every time I travel near canal roads I make it a point to check the tire to remove the glass before it sticks in too deep and make a puncture. will try marathon plus soon

[@carywatmore]

I watched this video a few times and finally tried 75 psi for my front Marathon Racer and 85 psi for the rear MR. I’m 56-57kgs and the ride was so much better. I do brush my tyres when they pick up stuff. Perhaps that’s why i haven’t had a puncture from the road. One feedback on Continental Contact Urban i do have it to check for bulges along the side walls - there have been a few reported cases of bulges and even cracks - even if you inflate to 100 psi every week and check that the brake shoes are not close to the tyre - ie well seated in the middle of the rim’s braking surface.

You can but in comparison, schwalbe are better. - Marathons (+)/ Racer are better for Gravel/ off trail use. You feel the semi slick of the Urban in Sand, Snow and mud don't grip that much. (Obviously) - if carrying Cargo is your thing, taken a Schwalbe tire. The Low pressure of the tire ain't good for heavy weights on the Bike. Overall ... great Tire for EDC use and faster Rider.

Hi Pam And Gilbert. You should try velotto brand tires (korea brand, made in indonesia), they are very light weight (±150 grams) very slim, attractive, and quite durable too.

[@luvinfunvan]

Really nicely done video, good work! It should be noted however that the estimates on rolling resistance are strictly lab environment. Much like those on some third party websites and do not reflect real world testing by organizations like BQ. Time and again it has been proven that higher volume, lower pressures provide much lower overall resistance and much higher efficiency. I can certainly concur anecdotally that running Primo Comets (the last of the great high volume 16 tires) at 60psi produces significantly faster and less tiring arrival times. The bonus is better comfort and off-road traction on gravel paths. I’m hoping that someone will bring back a high volume 16” tire like the Primo or even better Scorcher again.

[@2Bikes4Adventure]

We agree. In this video, we didn’t want to go too deep and start discussing “Berto’s 15% tire deflection rule” or the advantage of wider/shorter vs narrower/longer footprints. Maybe in a follow-up video if this one raises enough interest.

I think the optimum setup would be a Marathon/Marathon Plus on the rear and a sportier tire on the front but for simplicity and not to worry, I use Marathon Plus front & rear.

[@2Bikes4Adventure]

Putting the most durable and puncture-proof tire available (M+) at the back is a wise decision.

[@adrianlw2750]

I have thought about that mix as an option but not yet tried. My Brompton came with the standard Marathon Racer tyres which I found worked well for my predominantly leisure non-urban rides. I replaced both with Marathon Plus for this last winter, even though Brompton do not recommend that tyre for the bike. I have got on well with them. The fender/mudguard clearance is only just acceptable though, but the fold was unaffected. I cannot honestly say that I noticed any speed/effort difference of any importance to me. The confidence factor rose significantly as regards puncture resistance though. Perhaps only one caveat from my experience, the Plus are not as grippy and also tend to “tramline” more over some road features which means that in the wet extra riding care is desirable - for an experienced rider this is not a problem in my view as road surfaces knowledge/understanding will be a given. Fitting the Plus is all about correct technique and this was simply not an issue for me.

[@jacc88888]

@@adrianlw2750 interesting to read about the marathon plus having less grip. This is quite concerning for me as I want a tyre that has the best possible grip in slippery condition when on my Brompton. Do you have any recommendations? Puncture resistance is also important to me but not as important as safety.

[@adrianlw2750]

@@jacc88888 - as best possible grip in slippery conditions is your priority, I would be inclined to stay with the standard Marathon Racer as the “Plus” doesn’t fit that brief as well in my view. Carry a spare inner tube at all times and be 100% familiar with getting the wheels off and back on. Alternatively, you might consider a “Plus” for the back wheel only and see how you get on, perhaps using 90 psi rather than 100 psi. Depends on your weight/luggage carried at the back really. I’m a 80kg rider and luggage is only carried at the front. 90 psi is fine for me but I prefer to keep at 100 for the marginally better rolling resistance. Reduced pressure may improve confidence and will tend to reduce tendency to tramline. Hope this helps.

[@gd3593]

Love the detail you guys go into, really helps us make a good choice - just the other day I swapped out my Marathon Racers for Conti Urban Contacts and boy what a difference! don't think I could ever go back - they're faster, more comfy and grippier. Just one question though, I only weigh 55KG and have pumped up the front tyre to 80 psi and 90 on the rear - is there a scientific formula to calculate the optimum psi based on a person's weight?

[@2Bikes4Adventure]

Interesting you mention the swap to Continental Urban. We are now presently touring for the first time on those tires as well (having switched from Schwalbe Marathon). We will likely discuss our conclusion in a follow up video. Concerning ideal pressure, in addition to total weight, the road surface condition plays a very significant factor. It’s basically a compromise between comfort, pinch flat protection and rolling resistance. It would also make a good follow-up video. Until then, the pressures you are suggesting seem comparable to ours.

[@gd3593]

​@@2Bikes4Adventure I think you're right about the ideal pressure, many factors to consider, including subjectivity in the absence of actual scientific data - I'll play around with the pressures to find that sweet spot!

Not sure about the GCN test, but proper tire pressure has many variables, including rider weight and bike load.

Wow. This was way more detailed than I expected. I was hoping for more of a bike trail handling type video, but you may already have a few of those in your channel which I am now going to be checking out. We have been riding our bikes over the decades (a mix of full size and folders) on pavement and hard pack gravel (rail trails, etc) and considering Bromptons due to the small folded size (we are going to be going Fulltime RV in about 18 months and space is a huge concern). I still don’t know what to expect on the smaller wheels on mostly gravel trails.

[@2Bikes4Adventure]

There’s a good reason why Brompton’s tag line is “made for cities”. Its small wheels would likely struggle with anything tougher than a hard-pack (rail-trail type*) roads. A dirt road with discernable small rocks would necessitate constant course corrections (and vibrations) preventing any significant forward momentum. In wet condition, it would become even worst. Unfortunately, there are no easily available Brompton compatible tires that would solve that issue (its frame/brakes cannot accept wider tires). *Something like the GAP-C&O trail in the USA would be fine

[@sssxxxttt]

@@2Bikes4Adventure I believe wider tires will not help much on coarser roads. You will struggle keeping a direction. Maybe a reason cross country MTB's have gone from 26" to 29"

Indeed. Wouldn’t mind some options in the 40-349 range however (Ex.: Greenspeed Scorcher). Brompton equipped with Schwalbe Big Apple would be something to try on (dry) gravel trail as well.

One afterthought. If you are riding the Brompton Electric, some of the values change a bit as for instance, the motor helps overcome the rolling resistance.

You raise a good point concerning E-Bike. The Kojak and Schwalbe One are NOT rated for Electric bikes. Schwalbe Marathon, Marathon Plus and Racer are rated E-25 (regular “25km/h” Pedelecs like the eBrompton) Continental Contact Urban are rated E-50 (Faster S-Pedelec)

[@austinswallow]

You don't mention the Tannus tyre, a solid tyre (made in Korea), these are available in 32-349 size, in a range of colours. I have been using these on my Bromptons for about 4 years or so now, being solid they are always fully inflated to mimic 100psi. The big advantage of a Tannus tyre is of course, they do not ever puncture, a very BIG plus for me - 3 punctures in a week on a Schwalbe Marathon Plus did it for me, I have not looked back. Slightly heavier than the Marathon Plus, but, the tyre pump is redundant, so removed from the bike. Tannus claim that the tyres have a life of around 6,000 miles, the rear tyre is about half that. Can be expensive, but when adding the cost for replacement inner tubes (assuming repairs are DIY), then not as expensive, if the puncture is repaired by a cycle shop then they start to look much cheaper. The other disadvantage is that the tyres are hard work to fit, it is a struggle to get the tyre on - it is held with pins that engage with the rim, once on, that is it! I would not wish to return to a pneumatic tyre such is the sheer satisfaction of total reliability (I always seemed to get a puncture when it was raining and at the furthest point away from my return home - why was that?) and that is a joy to be had. Also, a colour other than regular black is great, although in my experience, the tyres all turn a greyish colour through use. Thanks for this, I like these videos you do on the Bromptons, the best folding bike by far!

[@2Bikes4Adventure]

When the sea has flooded the cycle track, I have ridden through the waves a few times without any concerns! Comfort-wise, I just don't even think about it, I don't worry unduly about kerbs (a lot of our pavements are now shared with pedestrians) and our roads are full of potholes (terrible neglect).

Love the vid . I’ve been using marathon tyres for 4 years and I love them . My question is what is the perfect tyre pressure for riders weight . I’m 170 kg I run my tyres at 110 psi but I’m breaking spokes if I lower tyre presser I get tyre slide around corners are there wider tyres better suited for riders weight

[@2Bikes4Adventure]

Hi Steven. The Brompton maximum load is 110kg (the limit has more to do with the steel frame/weld constraints than tire characteristics). Having wider tires ( ex.: 40mm / 1.60”) would permit lower pressure (and reduce likelihood of spoke failure), but unfortunately, such tires won’t fit on a Brompton. So, with standard 37mm tire, high load will require maximum pressure.

Having had two punctures of my Plus tyres in past year which penetrated halfway down the side of the tyre I’m thinking the theoretical protection offered by the thick gel inside the Plus isn’t so effective from that direction. Of course, I don’t know how many punctures I’ve avoided. But I’m now wondering whether the Racer’s harder nylon membrane would have prevented penetration by thorns. Changing the Plus is hard work at home. On the road I cycle on the ‘flat’ Plus and that doesn’t seem to damage the tyre (though the inner tube gets shredded). Somehow I doubt the Racer would stand up to sidewall abuse like that!

It goes without saying, sidewalls are always less protected than the main treads. Not sure the Racer would have fared better in such a situation. The next level of protection may be an airless tire (like the Tannus). We have never tried them, but some subscribers seem very satisfied with them.

@@2Bikes4Adventure but it does suggest the Plus’ advantage might be overstated. The Plus relies on its thick gel to absorb the object, but this looks to be only half as effective at 45 degrees. The Racer’s nylon coat appears to have equal effect at any angle. In your graphic the testing appeared only to be exerted at 90 degrees from the horizontal. It would be interesting to compare Racer and Plus at other points of entry eg 45 and 67 degrees.

Hi Peter, One of the references we used in our video is www.bicyclerollingresistance.com . Each tire evaluation involves 20 punctures, 10 on the centre of the main tread and 10 on the sidewall (2 different needles are used, one blunt, one sharp (so, 5 punctures each per location)). Sidewall puncture score for the Marathon Plus is 21 (thread is 129). Racer sidewall score is 13 (thread is 97).

@@2Bikes4Adventure thanks, that covers both angles (literally!). Plus markedly better in all situations for puncture protection. QED.

Excellent analysis, thank you. Have you any experience with the Continental?

[@2Bikes4Adventure]

We haven’t try them yet.

Hello ♥️, why don’t you do a Tanus tire on a brompton review pros and cons?! Or a Tunus Armur combination with these tires for best protection and speed That would be awesome and unique specially with your informative way of reviewing ! There is no such a video about Tanus tires or Tanus Armur on brompton.

Excellent suggestion

[@Trenchant468]

Love your videos! I’d be very interested to get your perspective on adding fatter tires (needing bigger rims), such as the Schwalbe Big Apple, and if you think the Brompton outfitted this way would be off-road worthy?

[@2Bikes4Adventure]

Brompton owners wishing for larger tires face 2 problems: 1. Front fork and rear triangle clearance cannot accommodate much more than 37mm wide tires (BigApple are 50mm). 2. Limited to non-existent choice of larger tires in the 349mm radius format (BigApple 16” are 305 mm). Installing new rims (305mm) and new brakes would be required to install BigApples (www.kinetics-online.co.uk/folding-bikes/brompton/brompton-wheel-sizes/)

@@2Bikes4Adventure I knew you would know. Some of those mods (from Scotland-Oy!) would be perfect. Now I have to decide if I should keep my truly great Bike Friday with the large fold format, or strive for a modified Brompton. That assumes I could ride it on light trails.

[@2Bikes4Adventure]

@Happy, we never had the chance to try a BikeFriday (is yours a NWT?), but with its 20” wheels and wider gear range, we would guess it’s better suited for long distance touring (and even a little bit of off-road) than the Brompton as long as you are not planning too many intermodal trips.

@@2Bikes4Adventure Yes NWT e-bike (not optional for me) with 32"x24"x12" fold. I n my search I focused on a bike I could lift, store, and transport, for light trail riding, not distance touring. And I really dislike riding with traffic. (It's so new I've only ridden it about 1 mile, and not yet on gravel or trails.) But now I'm considering how limiting the larger fold is for urban uses, metropolitan travel, and entering establishments. I ruled out Brompton due to proprietary parts, narrow 16" tires, and electric which can't go on planes. But now I'm thinking maybe a Brompton with the right mods...? (I'm beginning to appreciate why real bikers have several bikes.) For the record, the ride is great on the NWT-only slightly twitchy, 18 gears, and the electric is seamless. I was less enthused when I rode an e-Brompton, but it was just around a city block as a trial.

@Happy, the solution is to find the right balance between compact size and riding quality. Depending on the primary use case, the answer will likely be different from one rider to the next. Obviously, having more than one bicycle facilitates somewhat the decision process.
