Schwalbe Marathon Plus tyres for a Dahon?

After repeatedly getting punctures on my Mu P8 which currently has Marathon Racers (quite worn out now) I've decided to replace them with Marathon Plus' because of their superior puncture resistance, but I've a few questions:

Are the Marathon+ the same size as the Marathon Racers? The reason I ask is that the Mu's wheels are quite narrow so I'm concerned that a bigger/wider tyre may not fit the wheel properly and/or may interfere with the mudguards.

Also, I've heard that Marathon Pluses are difficult to fit - any comments from M+ users?
Finally, what's the ride and handling like?

TIA

Johno

Marathon PLUS Tread HS 348, 710 grams, 45 - 70 lbs pressure, ETRTO 47-406 20 x 1.75
Racer Kevlar bead , tread HS 366, foldable, dual compound, 290 grams, 50 - 85 lbs pressure, ETRTO 40-406, 20 x 1.5

the racer is a complete different tire ..... in the kevlar version 400 grams lighter than the plus .... I only recomend the Plus for the hardest and most ridicoulous glass thorn old metal nasty commute ( where you have to arrive in time ) ..... It will slow you down , no question. Of course having said that if you repair the tube more than once a week than its the perfect choice....

But if you are at the end of your current tires and have had 3 punctures in the last 3 months than I wouldnt take that tire but a fresh set of tubes and new lighter tires...

So you'd recommend sticking with lighter tyres, maybe even sticking with the Marathon Racers?

We've been riding on 1.35" Marathon Plus tires on our custom Bike Fridays for about 1 1/2 years - mostly city riding where there is always lots of nasty stuff by the edge of the roadway. Zero flats to date. Neither the wife or I think they are SLOW. Guess once you get to 65 (and past) going faster than everyone else just isn't in the cards.

We have very cheap, 1.75" Kendas on our Pocket 8 BF's, and they did very well on the 8-10 miles we rode on the C&O Towpath on Saturday.

Possibly the problem is that we have never ridden on light, fast tires. Maybe in the next lifetime!

Whether to choose Marathon Plus depends on how and why you use your bike.

I was getting a puncture every one to two weeks. Getting a puncture meant I would almost certainly miss the train and end up repairing the flat or replacing the tube in the dark and/or in pouring rain and inevitably getting dirty hands and arriving late to work.

Yup - Marathon Plusses are heavy (however, they seem to roll pretty well) but I've only had one puncture in 2,000 miles.

I think they are a little harder to fit than some tyres but not difficult.

It's all about trade offs.

I have Marathon Plus on my tourer. Admittedly weight isn't an issue on a touring bike, so you might like to take that into account. However they roll well, the ride is fine and they are superbly tough. I've used them for about 4000 miles without ever having a puncture. They are tight to put on, but if you never puncture, putting them on and taking them off isn't an issue.

no I dont recomend that in general ...... I only gave you some facts to compare ... and maybe a hint whats YOU prefer to do ...
As I said for a commuter who has to catch a train or be on time everyday ... for a world traveller who runs through thorn infested roads .. there is no substitute .....

and yes they roll pretty well when they are going .. but compared to lighter tires like the racer or Kojak or Durano they will not accelarate and feel like molasses compared tot he nimble feeling of a light tire ....

I sell both .... but this is a very personal choice ( almost as bad as Saddles) therefore I usually dont suggest anything ...lol

Although I haven't tried marathon plus in 20" sizes, for the 700c sizes it's advisable to stick to one of the wider sizes.

they have a very stiff sidewall and the built in liner makes the tire spread out, so mounting 28mm is extremely difficult.

wider tires will give you more sidewall to work with, so they'll be easier to mount, and offer better comfort because the tires have more room to deflect.

one other thing, it's preferable to have a wide rim for these.

I had the standard Marathons 20" x 1.5 on my bike (until a couple of Conti Sports arrived today) . They are excellent for city use and I've had no punctures so far. I ride the bike about 120 miles a week, plus a little more on my training rollers with the Marathons fitted.

They are comfortable, and weigh I think 435g, only 100 g more than the treadless Sport Contacts I've just fitted. I like the Marathons if you can get them, for daily use, they don't seem to have much in the way of excessive rolling resistance to worry me and they are comfortable. Bike is a Vitesse D7.

Your Marathon Racer is a 40-406 - 20" x 1.5 tyre, the Marathon is also a 40-406 - 20" x 1.5 and will fit but you might find it 'fat'. It's much heavier.

The Marathon Plus is a skinnier 35-406, 20" x 1.35. I don't think you'll have problems fitting them if you got nylon tyre levers, and patience, but I haven't tried. I did fit the 'tricky' wire bead Contis without any problems.

The Continental Sport Contact 28-406 20 x 1 1/8 will also fit, 90-102 psi - 5.5 - 7 bar) and weighs only a little more than the M. Racer. They come with replacement tubes with Presta valves (in the UK) . The M. Kojak gets good reports but I haven't tried them. But tyres are such a personal choice, it's hard to make recommendations.

The Marathon Racer though is a lightweight at 275g. Whatever you whack on there, if it's heavier or slower, you'll notice the difference.

Jur is pretty good on tyres, PM him?

Someone at work mentioned the Conti's Sport Contact which appear to have a good balance between performance and durability so I'm also considering those, but I've just had another puncture on the same wheel as last week so now I'm also leaning towards getting the Marathon Plus just for the rear wheel.

Next question: is it advisable to mix tyres between back and front i.e. Marathon Racer on front and M Plus on rear?

My fairly fast commute through London is 13 miles each way.

I've just read Sehdon Brown's tyre sizing guide and must admit it's confusing. My Dahon's wheels have an ETRO labelled as 20" 406x17 where Sheldon's info states that the numbers are the other way around i.e. 17 406

Given that the numbers are ETRTO numbers and not ETRO as per the Dahon's wheel, I'm guessing that Mr Brown's info is correct?

I'm still confused about how to work out which tyres will fit my bike's wheels


Can anyone help or advise?

TIA

That video had me asleep before the tyre was on.

Yours truly also posted a youtube viddy on how to remove a Marathon Plus from a Birdy wheel, one of the hardest combinations I can think of. Look mum, no tools!

http://www.youtube.com/watch?v=7xZ6Lybtc8Q

with some description in this thread:
http://www.bikeforums.net/showthread.php?532204

On Marathon Plus, I have gotten about 10,000km on the rear on my Birdy which is very good mileage indeed from a rear. It was showing the blue layer when it finally blew out a sidewall one day.

I hated the Marathon Plus. It wallowed terribly. I also got punctures, about 2 or 3. The blue stuff on the 1.35" narrow Plus was not enough to deter glass shards. They got through on the edge of the blue strip.

I'm pretty certain the Marathon Plus will fit your wheel. Width is pretty forgiving.

Mudguards are usually somewhat adjustable in case there is interference.

For puncture-proofing, I use Slime tyre liners, and that I find works best. EXCEPT these tend to cause punctures from the cut ends; so these need to be sanded down to very smooth.

406mm diameter, 17mm width

minimum size you want is 20x1.125 (406x28) and widest you want is about 20x2.1

As others have said, they ride pretty well but are a bit heavy. Have them on my BF NWT and on a regular Trek hybrid.

That being said, in less than 1700 km of riding, my rear tire was punctured by a 2-inch straight nail. It went from the tread right through to the opposite sidewall. Ouch...

That's a good point about the narrow Plus - my current Marathon Racers are 1.5" so I was considering the 1.35 but in light of your experience, maybe I'm batter off getting the 1.75 (one-sixth wider than current tyre) and hope it'll not interfere with the mudguards.

Thanks for your feedback, much appreciated

I took the bike out today with Conti Sport Contacts fitted, and Slime in the tubes. First impressions; bike is noticably quicker than it was on the Marathons. Handling is nimbler, and comfort is only slightly compromised. The bike ( Vitesse D7) feels rather like my Hammerhead did - that combination of ease of pedalling, responsiveness, and road feel.

Puncture resistance? I think for a daily commuter, I'd keep the Marathons - I'd hate to miss a train in the evening. As the Dahon is my fitness bike, I'll leave the Conti Sport Contacts fitted.

They are decidedly fast and fun.

(I know the brake pad needs adjusting )

After taking into account all the feedback I've had from you all (many thanks), I decided to order a Marathon Plus 1.75 for my rear wheel - that'll mean that I'll have a Marathon Racer 1.5 on the front and the 1.75 Marathon Plus on the back wheel which bears most of the rider weight.

Hopefully that combo will work fine for my commute and I'll hopefully be getting far less - if any - punctures on the rear wheel.

Thanks again

It occurred (a bit late!) to me that you could get a good idea of fitment by setting the mudguards to maximum clearance and measuring the clearance between the current tyre and the guards, giving you an estimate of whether the new tyre would fit.

Let us know if you have a problem, likely nothing that a bit of tool-wielding couldn't fix.

I think most 20" dahons come with 1.75 as default.

I've had marathon plus tyres on my GoBike for a while now, they add a lot to the bikes weight, & I still got a puncture in Toulouse, France.
IMHO Big Apples or BA liteskins would be better.
