Tire Width Question for NWT
 
Hi all, currently using 20x1.35 Schwalbe Marathon Pluses on my NWT and noticed that BikeTiresDirect has a pretty sweet deal on Marathon Pluses but they only have 20x1.75s. Will these make any sort of difference in my riding?

Right now, short rides of 24-60 kms on pavement but looking to ramp up to 200+ again on same, unloaded. Loaded touring is possible in the future on a variety of paved roads.

Thanks!

There are 2* different so-called 20" wheel sizes and they are not interchangeable. One is ETRTO 451 and corresponds to 20" x 1-1/8 up to 20"x 1-3/8. Anything 20" x 1-1/2 or wider is actually a smaller wheel, ETRTO 406.

Sounds like you have 451 wheels on your NWT and the tires BTD has in stock are 406 size.

* Actually 3, but the ETRTO 419 size is one I've never seen in practice. For the gory details, see Sheldon Brown's excellent exposition of tire sizes at http://sheldonbrown.com/tire-sizing.html

Thanks dorkypants for the reply. I went and checked on my tires and they are 35-406 and HS 348.

So, according to the Schwalbe site, the 35 refers to a width of 35 mm and a tire inner diameter of 406.

It should fit.

I believe Bike Friday claims that 20 x 1.75" fits on a NWT although it is pretty clear to me that bigger tires could fit ... judging from a set of Primo Comet 20 x 1.75" tires on my NWT at the moment.

Thanks invisiblehand, most comforting to know. Along with doing some more reading online and looking at the BF site itself, I went ahead and ordered a bunch of Pluses and a Durano. :)

Anytime IronMac.

A bunch of them! You must be planning on a lot of riding!

The main difference of using Marathon Pluses will be the feeling that you are towing a couple bricks on the end of a string behind your bike. Don't do it - especially if LD riding is in your plans. To ride 200kms+ a day you need an efficient bike and Pluses are anything, but efficient.

Get some Greenspeed Scorchers. I use them on my NWT & Tikit - they are fast, comfy and zero flats for me in 4 combined seasons [NWT + Tikit] of city riding.

Everyone who's tried my bikes has bought Scorchers and loved them.

Vik, yeah, you mentioned that in another thread. I would have tried out the Scorchers but BTD did not have them on sale so I got the Durano instead.

invisiblehand, as for buying a bunch of tires, I wanted to maximize the savings from the BTD sale so I got 3 Pluses and 1 Durano. I think that that should be good enough for a few years. With any luck, my next tours may be up to Malaysia or better yet Cambodia (I'm in Singapore for the next little while). There may also be a tour down in the US next year (highly, highly doubtful) or RAGBRAI in 2012.
